     The necessary appro&al for concrete placing will be obtained prior to placing and

    the element that needs to be cast will be inspected beforehand. All unwanted debrisand material such as water and loose soil will be remo&ed from the element before

    concrete placing. ' "ours after mi%ing the concrete it will be placed in its ?nal

    position.

    A slump test will be conducted on the batch of cement when it arri&es on site. The

    measured slump will be within the following limits0

    3or reinforced walls and slabs J @;mm J '-mm

    3or reinforced Koors J between F;mm J '-mm

     The slump test will be carried out in accordance with SAS method F7' and shall be

    determined from the appro&ed a&erage slump of the appro&ed trial mi% as pertender speci?cations for structural concrete.

    In order to achie&e the re,uired slump no additional water will be added to the mi%.

    In order to ensure that the concrete can be placed in the corners of the formwor=

    and around the reinforcing without segregation the consistency of the concrete will

    be of such standard to achie&e this without segregation of the mi% or the bleeding

    of water.

     The concrete will be placed &ertically where possible to pre&ent segregation of the

    mi% or the displacement of the reinforcing. The concrete will not be allowed to free

    fall a height e%ceeding 1.-m unless appro&ed by the Engineer. The concrete will be

    brought in in layers of 

    -;mm thic=ness and will not be wor=ed by means of a &ibrator to Kow laterally so

    as to pre&ent segregation.

     The angle of the shoot will be controlled to pre&ent segregation.
