2. IS 383 (1970): Specification for Coarse and Fine Aggregates from
Natural Sources For Concrete [CED 2: Cement and Concrete]
3. What are FA and CA?
Aggregate passing through 4.75 mm sieve are defined as fine
aggregate
Aggregate retained on 4.75 mm sieve are identified as Coarse
Aggregate.
108
4. What is the Specified size of Metal to be used as CA?
20 mm Hard Granite crushed metal is specified by IS 456
Basalt (✓) Granite (✓)
5. COARSE AGGREGATE Coarse aggregates refer to irregular and granular materials crushed stone
used for making concrete. In most cases, COARSE AGGREGATE is
naturally occurring and can be obtained by blasting quarries or crushing
them by hand or crushers. Their angularity and strength affect the concrete
in numerous ways. Needless to say, the selection of these aggregates is a
very important process.
6. Size of Coarse Aggregate Materials that are large enough to be retained on the 4.7mm sieve size
usually constitute coarse aggregates nominal size of 20mm.
The size of coarse aggregates affects several aspects of the concrete,
mainly strength and workability, and the amount of water needed for the
concrete mix. It also helps determine how much fine aggregate is needed
to produce a concrete batch. The bigger the size, the smaller is its bondable
surface area for cement, sand and water; the less water and fine aggregate
is needed with concrete mixes.
7. The size of the coarse aggregate determines the cement to water ratio Less water means a stronger mix, but it also becomes less workable. One
important factor is the space between TMT Bars. The aggregate needs to
be smaller than the space between internal reinforcements. This will allow
the aggregate to pass between the rebar and settle evenly throughout the
structure.
109
8. Grading of Coarse Aggregate The grading of aggregate is its classification according to the average size
of the particles. It is important that the grading is kept constant for concrete
batches. The aggregate particles need to be of a consistent size for an even
grading. Similar shaped coarse aggregates make the concrete more
cohesive and uniform.
9. Shape of Coarse Aggregate The characteristic of the parent rock from which coarse aggregates is
produced and also the type of crusher used to influence the shape of the
aggregates. They may be round, angular or completely irregular.
Angular Aggregates are stronger and more durable. Flaky or elongated
Aggregates result in segregation in the concrete.
10. Strength of Coarse Aggregate
The strength of the actual material will determine the final strength of the
concrete mix. Some rocks and stones are stronger than others thus, giving
higher resistance to cracking and crushing. Granite, for example, is far
stronger than limestone. Therefore, it is a common aggregate used.
These properties determine the final quality and strength of a concrete
batch. The size, grading, shape, strength and water absorption of the
aggregate all influence the final concrete mix in various ways, so
contractors need to keep an eye on these variables.

suitable proportions. It should pass BIS No. 480 mesh sieve and should not
pass BIS No. 15 sieve. The fineness modulus of sand should be between 2
and 3.
112
Function of Sand in Mortar:
The sand is used in mortar and concrete for the following purposes:
(1) Bulk:
It does not increase the strength of mortar. But it acts as adulterant. Hence the
bulk or volume of mortar is increased which results in reduction of cost.
(2) Setting:
If building material is fat lime, the carbon dioxide is absorbed through the voids
of sand and setting of fat lime occurs effectively.
(3) Shrinkage:
It prevents excessive shrinkage of the mortar in the course of drying and hence
the cracking of mortar during setting is avoided.
(4) Strength:
It helps in the adjustment of strength of mortar or concrete by variation of its
proportion with cement or lime. It also increases the resistance of mortar against
crushing.
(5) Surface Area:
It subdivides the paste of the binding material into a thin film and thus more
surface area is offered for its spreading and adhering.
Tests Conducted for Sand:
Following tests may be carried out to ascertain the properties of sand:
I. A glass of water is taken and some quantity of sand is placed in it. It is
then vigorously shaken and allowed to settle. If clay is present in sand, its
distinct layer is formed at top of sand.
II. For detecting the presence of organic impurities in sand, the solution of
sodium hydroxide or caustic soda is added to the sand and it is stirred. If
colour of solution changes to brown, it indicates the presence of organic
matter.
III. The sand is actually tasted and from its taste, the presence of salts is
known.
IV. The sand is taken from a heap and it is rubbed against the fingers. If
fingers are stained, it indicates that the sand contains earthy matter.
113
V. The colour of sand will indicate the purity of sand. The size and sharpness
of grains may be examined by touching and by observing with eye.
VI. For knowing fineness, durability, void ratio, etc., the sand should be
examined by the mechanical analysis.
.
Visualization Test
The size of particles and sharpness of sand (fine aggregates) is checked
by visualization. Sand should be free from organic impurities (like shell,
shingle, and other impurities) or they should be in limits which are easily
identified by visualization
Taste Test
You Should taste a pinch of sand and if it taste salty ,the salt must be
present in sand and hence it should not be used at all in any construction.
such sand is naturally from the river but either it is sea sand or from an
area of river frequently affected by tidal water near the sea.
114
CLAY TEST:
The presence of clay in the sand effect the performance of the concrete strength.
So the presence of clay in sand can be detected by doing two physical test on
sand
➢ Take a some amount of sand in to your hand and drop it in to the glass
which contain water. After drooping the sand than shake the glass. If clay
is present in the sand it will make a separate layer above the water surface.
So it indicate sand is not good.
➢ In another simple test take some amount of sand in your hand and then
drop it. If sand stick in to you fingers it indicate the presence of clay in
sand.

119
What is Cement Mortar
The term mortar is used to indicate a paste prepared by adding required quantity
of water to a mixture of binding material like cement or lime and fine aggregate
like sand.
The above two components of mortar, namely, the binding material and fine
aggregate are sometimes referred to as the matrix and adulterant respectively.
The matrix binds the particles of the adulterant and as such, the durability, quality
and strength of mortar will mainly depend on the quantity and quality of the
matrix. The combined effect of the two components of mortar is that the mass is
able to bind the bricks or stones firmly.
Sand give strength to the mortars. Sand prevent excessive cracking due to
shrinkage of the paste.
If we use cement as a binder it will be Cement Mortar and if we use lime it will be
Lime Mortar.
The strength of mortars decreases as the proportion and increases.
In the dry state, the mixture is made up and down with the help of a phawrah, then
the water is added to this mixture, and after mixing it up and down, a
homogeneous paste of cement mortar is formed.
Cement mortar requires proper curing to achieve proper strength.
In these types of mortar, the ratio of sand to cement varies from 1: 2 to 6, or
volume depending on the strength and importance of the work.

Water Cement Ratio
• Strength of concrete primarily depends upon the strength of cement paste.
• Strength of cement paste decreases upon the dilution of paste.
• The strength of paste increases with cement content and decreases with water content.
• Water cement ratio is the ratio of cement and water utilized in the preparation of concrete.
• The quantity of water used at mixing concrete is very important.
• The usual tendency is to use too much water that gives a more workable mix, but it doesn’t give sound concrete.
• Too much water results in the segregation of aggregates and give porous concrete of low strength and low density.
• Excess Water Cement Ratio results in Less strength of Concrete.
• 35 to 40 water cement ratio is more practical for Good Concrete.
• For more workability we have to use Plasticizers or Super Plasticizers in Concrete
Graph-1
Water-cement ratio from the given graph of 28 days characteristic compressive strength of concrete and w/c ratio, here we used target mean strength.
