Mix designs for concrete block

method for designing mixes for concrete masonry is called the FM method. FM stands for fineness modulus, an index number roughly proportional to the average size of the particles in a given aggregate. The coarser the aggregate, the higher the FM. While all block mixes require at least one aggregate, a producer, for a variety of reasons, might decide

Concrete Batching, Mixing, Placing and Compaction of Concrete

There are two categories of ready-mixed concrete: central-mixed and transit mixed or truck mixed. In the first category, mixing is done in a central plant and then concrete is transported in an agitator truck. In the second category, the materials are batched at a central plant but are mixed in a truck. Concrete Placing and Compaction of Concrete
