    Hanlon Concrete manufacture and supply ready mixed concrete and cementproducts for Ireland's commercial and large-scale industrial construction

    customers, as well as providing a prompt Readymix delivery service for thesmaller domestic home build customer and small and medium scale builders in

    Ireland.

    Our large fleet of Ready mix cement mixers, artic's and cement trucks ensureswe can respond and deliver the required volume of Readymix regardless of thequantity required. Our concrete delivery schedule means our extensive fleet of

    6.5 cube bottles can be deployed to deliver for example a 2500 square metrehouse with the 25-30 cubic meters of readymix concrete foundation required in

    succession and on schedule for the construction work.

    Comparatively with the introduction of one of our artic trucks into the delivery

    schedule, with a capacity of 11 cubic meters of Ready Mix, we can deploy ourcombined fleet of 6.5 cube bottles and 11 cubes in a truck, ensuring supply of

    Readymix foundation on an industrial scale, capable of providing concrete forthe largest of commercial construction jobs.

    Our ready mix cement delivery locations cover deliveries to counties; Dublin,

    Kildare, Wicklow, Meath, Westmeath, Offaly, Laois and Carlow in the Leinsterregion of Ireland.

    Aggregate bins

    We have four number aggregate bins each holding 75 tons of materialThis allows us to tip the aggregate material into the bins with a dump truck

    directly from the pit thus doing away with having a man tied up on a loadingshovel all day.

    Aggregate weigh hopper

    The capacity of this hopper is 13000kgs. It has four number load cells for

    accurately recording the correct weight.

    Aggregate Holding hopperThis has a holding capacity of 8000kgs and has a butterfly valve at bottom of

    hopper which is directly over the mixer.

    Pan Mixer

    This is a Teka 4500 with an maximum output of 3meters cubed of ready-mixper batch.

    It has two number discharge doors which means that two lorries can beunderneath at the one time so that when one is loaded it will automatically

    proceed to load the second lorry once his mix type has been entered into thebatching loading sequence in the computer.

    Cement Silos

    Cement Silo 1:This is a twin outlet single split silo with an overall capacity of 180 tons of

    cement.

    The two cement screws feed up to a cement weigh hopper in the batchingtower.

    Cement Silo 2:This is a single silo with a capacity of 120 tons. This can give us the option of

    being able to use other cementitious products (eg GGBF (Ground GranulatedBlast-Furnace Flag).

    This will allow us to be able to deliver for special design specification workwhich the N.R.A. sometimes request or on special construction projects where it

    can be required.

    Cement weigh hopperThis is positioned directly over the pan mixer and has three number load cells

    for accurate recording of correct weights.

    AdmixturesWe have a three compartment weighing vessel which caters for six different

    admixtures of our choice which again are in close proximity to the pan mixerand which is plumbed into the water discharge pipe to the mixer.

    Ready-mix is the most commonly used product inthe construction industry. It can be used for many

    projects and can be delivered to sites ready forimmediate placement.

    Concrete strength is measured in newtons. It

    can be got in varying characteristic strengthranging from 10n to 60n

    Water cement ratio has a major part to play in

    determining the strength of your mix and can

    be explained as follows.

    Concrete has three main ingredients which arecement, aggregate and water.

    Cement and water paste together is a suspension of

    cement particles in water. The more therefore youdilute the paste [ie the higher the water/cement

    ratio] the greater will be the distance between the

    individual particles in suspension and following onfrom that the more porous the hardened paste when

    excess water has evaporated.

    From this then derives the fact that the quantity

    and the quality of the paste to a very large degreegoverns the fresh and hardened properties of

    concrete and ultimately the strength of a given mix.

    In summary the most significant factors in concrete

    are:Unit water content

    Unit Cement contentUnit Water cement ratio

    Unit Aggregate properties

    Workability of fresh concreteAdmixture

    Unit Water

    The unit water of the mix determines the strength

    obtained for a given cement content and for a givenaggregate content and all together this is called a

    mix-design. Water determines the consistency of the

    overall mix. It is the ingredient which decides thedrying and shrinkage of a given mix although other

    factors ultimately also have a bearing on this as they

    are also water related.Aggregate Properties

    The grading of aggregates influence the amount

    of paste necessary to fill the voids between the

    aggregate particles. Good consistent gradation in theaggregates is recommended for consistent quality

    and workability.

    This is best achieved by varying the percentageof sand in the total aggregates per meter cubed.

    A good mix design will have the lowest sand

    percentage for the necessary workability andplacement of the concrete. This will result in the

    minimum water requirement and therefore the

    maximum strength due to the fact that the largest

    amount of course aggregates is used.

  • 7/31/2019 Batching Plant Operations

    4/17

    The shape of the aggregate also influences theproperties of the mix. Angular course aggregate

    require a higher percentage of sand [and then more

    water] then do rounded aggregate in concrete

    of equal workability but having said that properconsistent graded washed sand is far more important

    then aggregate for water requirement and

    workability.

    Cement contentThe strength of concrete increases with increasing

    the cement for a fixed water content, But also a stifflean-mix can have a higher strength then a standard

    wet mix if the water content of the lean-mix is low

    enough to give a lower water cement ratio then thewet mix.

    Water cement ratio

    This is best expressed as previously explained earlier.

    Cement/water paste is a suspension of cementparticles in water. The more water you apply to a

    given cement content the more voids appear in the

    suspension particles and the more porous it becomeson maturity.

    Workability of fresh concrete

    The workability of a concrete mix is closely alignedto the requirements necessary to place the concrete.

    The workability should always be kept to the

    minimum necessary to place the concrete. This

    has to be balanced of course against the properworkability to place the concrete and to get the

    proper compaction necessary for a proper finish and

    for durability.Workability can be measured by taking a slump test

    of the actual concrete prior to placing.

    AdmixturesCan and are used to improve certain qualities in

    concrete mixes. The common ones used are:

    Plasticiser

    Retarder

  • 7/31/2019 Batching Plant Operations

    5/17

    Air entraining agent

    Plasticiser

    Reduces water requirement and improvesworkability. It can act as a retarder and may effect

    strength in the early hours of development but will

    compliment the final compressive 28day strength.Retarders

    This admixture retards the setting time of ready-mix

    concrete and may also lead to low early strengths.Air entraining agent

    Entrained air in ready-mix reduces the water

    requirement and improves the cohesiveness and

    workability of the fresh concrete.It also improves resistance to frost and general

    durability of hardened concrete. It is recommended

    for all concrete which will be exposed to destructive

    weather elements on a regular basis.

    Guide to the testing of workability of concrete

    This is done by means of a slump test and will only

    be representative of the actual load of concrete youare placing. The tools/equipment you will require is as

    follows; small scoop, sample extraction scoop, cloth,

    slump rod, bucket or wheelbarrow, base plate, slumpcone and steel rule.

    Steps for taking slump test

    Get sample from the first 3meters cubed ofconcrete making sure it is representative of the

    width and depth of the discharged concrete.

    Remix the sample taken on a pre arranged clean

    area away from any contamination. Do this with ashovel for about 5 minutes.

    Set cone up sitting on base plate on level surface.

    Note that it is very important that the base plate islevel to have an accurate result.

    Stand on foot grip of cone to keep it steady both

    for pouring and for preparation for lifting whenfinished.

    Fill the cone in three equals layers.

    Rod each layer twenty five times spreading the

    blows evenly over the area ensuring that you

  • 7/31/2019 Batching Plant Operations

    6/17

    only rod the layer below. Use only the standard

    recommended rod.

    Heap up the concrete above the top of the conebefore commencing to rod the third and final layer.

    Clean the spillage from the side of the cone and

    from around the base plate making sure that theconcrete at the top of the cone is finished nice and

    flush.

    Having been standing on the foot grip of coneall this time keeping it steady release your feet

    away but make sure you apply downward pressure

    with your hands on cone until feet are fully clear.

    Carefully lift the cone straight up and clear slowlybut not too slow. Guide time of between 5 to 10

    seconds.

    Place cone upside down beside concrete ensuring it

    is on base plate.Place slump rod across top of cone and over

    concrete.Measure the distance from the underside of the rod

    to the highest point of the concrete and this will

    give you your true slump.Record the result.

    If the result is not true take another sample. If

    it again is not true get advice from your senior

    advisor

    When bagged cement is used, the field mix proportions are usually given in terms of designated amounts of fineand coarse aggregate per bag (or per 94 pounds) of cement. The amount of material that is mixed at a time iscalled a batch. The size of a batch is usualy designated by the number of bags of cement it contains, such as afour-bag batch, a six-bag batch, and so forth.

    The process of weighing out or measuring out the ingredients for a batch of concrete is called batching. Whenmixing is to be done by hand, the size of the batch depends upon the number of persons available to turn it withhand tools. When mixing is to be done by machine, the size of the batch depends upon the rated capacity of themixer. The rated capacity of a mixer is given in terms of cubic feet of mixed concrete, not of dry ingredients. Onlarge jobs, the aggregate is weighed out in an aggregate (usually shortened to " "),like the one shown in figure 6-5.

    Whenever possible, a batch plant is located near to and used in conjunction with a crushing and screening plant.In a crushing and , stone is crushed into various particle sizes, which are then screened intoseparate piles. In a screening , the aggregate in its natural state is screened by sizes into separate piles.

    The , which is usually portable and can be taken apart and moved from site to site, is generally setup adjacent to the pile of screened aggregate. The plant may include separate hoppers for several sizes of fineand coarse aggregates, or only one hopper for fine aggregate and another for coarse aggregate. It may have oneor more divided hoppers, each containing two or more separate compartments for different sizes of aggregates.

    Each storage hopper or storage hopper compartment can be discharged into a weigh box, which can, in turn, be

    7/17

    discharged into a mixer or a batch truck. When a specific weight of aggregate is called for, the operator sets theweight on a beam scale.

    The operator then opens the discharge chute on the storage hopper. When the desired weight is reached in theweigh box, the scale beam rises and the operator closes the storage hopper discharge chute. The operator thenopens the weigh box discharge chute, and the aggregate discharges into the mixer or batch truck. Batch plantaggregate storage hoppers are usually loaded with clamshell- equipped cranes.

    The following guidelines apply to the operation of batch plants:

    All personnel working in the batch plant area should wear hard hats at all times.

    While persons are working in conveyor line areas, the switches and controls should be secured and

    tagged so that no one can engage them until all personnel are clear.

    When hoppers are being loaded, personnel should stay away from the area of falling aggregate.

    The scale operator should be the only person on the scale platform during batching operations.

    Housekeeping of the charging area is important. Personnel should do everything possible to keep the

    area clean and free of spoiled material or overflow.

    Debris in aggregate causes much of the damage to conveyors. Keep the material clean at all times.

    Ready-mix concrete is a type ofconcrete that is manufactured in a factory or batching plant,

    according to a set recipe, and then delivered to a work site, by truck mounted transit mixers . This

    results in a precise mixture, allowing specialty concrete mixtures to be developed and implemented

    on construction sites. The first ready-mix factory was built in the 1930s, but the industry did not

    begin to expand significantly until the 1960s, and it has continued to grow since then.

    Ready-mix concrete is sometimes preferred over on-site concrete mixing because of the precision

    of the mixture and reduced work site confusion. However, using a pre-determined concrete mixture

    reduces flexibility, both in thesupply chain and in the actual components of the concrete.

    The leading ready-mix concrete supplier worldwide is theMexican concrete company Cemex; its

    main competitor isFrance-basedLafarge and the leading ready-mix concrete supplier in Middle

    East is theUnibeton Ready Mix.

    Ready Mixed Concrete is also referred as the customized concrete products for commercial

    purpose. the Ready-mix Concrete Company offer different concrete according to user's mix design

    or industrial standard.

    The Ready mixed concrete company is required to equip themselves with up-to-date equipments,such as transit mixer, concrete pump, and Concrete Batching Plant, which needs visualized

    production management software and also PLC controller.

    Ready Mixed Concrete, or RMC as it is popularly called, refers to concrete that is specifically

    manufactured for delivery to the customer's construction site in a freshly mixed and plastic or

    unhardened state. Concrete itself is a mixture of Portland cement, water and aggregates

    comprising sand and gravel or crushed stone. In traditional work sites, each of these materials is

    procured separately and mixed in specified proportions at site to make concrete. Ready Mixed

    Concrete is bought and sold by volume - usually expressed in cubic meters. RMC can be custom-

    made to suit different applications.

    Ready Mixed Concrete is manufactured under computer-controlled operations and transported andplaced at site using sophisticated equipment and methods. RMC assures its customers numerous

    benefits.

    [edit]Advantages of Ready mix Concrete over Site mix Concrete

    A centralised concrete batching plant can serve a wide area.

    The plants are located in areas zoned for industrial use, and yet the delivery trucks can

    service residential districts or inner cities.

    Better quality concrete is produced.

    Elimination of storage space for basic materials at site.

    Elimination of procurement / hiring of plant and machinery

    Wastage of basic materials is avoided.

    Labor associated with production of concrete is eliminated.

    Time required is greatly reduced.

    Noise and dust pollution at site is reduced.

    Reduce cost.

    [edit]Disadvantages of Ready-Mix Concrete

    The materials are batched at a central plant, and the mixing begins at that plant, so the

    traveling time from the plant to the site is critical over longer distances. Some sites are just too

    far away, though this is usually a commercial rather than technical issue.

    Generation of additional road traffic; furthermore, access roads, and site access have to be

    able to carry the weight of the truck and load. Concrete is approx. 2.5tonne per m. This

    problem can be overcome by utilizing so-called 'minimix' companies, using smaller 4m

    capacity mixers able to access more restricted sites.

    Concrete's limited timespan between mixing and going-off means that readymix should be

    placed within 120 minutes of batching at the plant. Modern additives modify precisely that

    timespan however, the amount of additive added to the mix is very important.
