Concrete Batching, Mixing, Placing and Compaction of Concrete

A secondary effect is that of grinding of the aggregate, particularly if soft; the grading thus becomes finer and the workability lower. In case of air entrained concrete, prolong mixing reduces the air content. Ready mixed concrete: If instead of being batched and mixed on site, concrete is delivered for placing from a central plant. It is ...
