Few candidates were able to:

-           explain the given concreting terms;
-           state the methods of transporting concrete mix on site.

However, majority of them failed to use annotated sketch(es) to illustrate the methods of checking the accuracy of setting out a rectangular building.

The expected response to question 1 is as given below:

1. Explanation of concreting terms

1. Batching:  Is the method of measuring concrete materials either by volume or weight.  OR The method of measuring the constituent (concrete) materials either by volume or by weight.

1. Water-cement ratio:  Weight of water to that of cement in a particular mix.  OR Proportion of water by weight to the proportion of cement by weight, that is added to a concrete mix.

1. Curing:  Is the process of keeping a placed mix damp to enable it attain the desired strength.

(c)        Three methods of transporting concrete

1. wheel barrow
2. head pan
3. chute
