(a) Explain the steps to be followed in preparing a concrete.
Explanation
The selection of materials is the first step in preparing a concrete. This involves selecting the type and quality of cement, fine aggregates, coarse aggregates, and water. The proportioning of materials involves determining the correct ratio of cement to fine aggregates to coarse aggregates to water. The mixing of materials involves combining the selected materials in the correct proportion and mixing them thoroughly. The placing of concrete involves pouring the mixed concrete into the mold or formwork. The compaction of concrete involves compacting the concrete to remove any air pockets and to achieve the desired density. The curing of concrete involves keeping the concrete moist to allow it to set and harden.
