Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...

Sequencing in Mix Design - National Precast Concrete Association

The most important factor affecting sequencing is the type of mixer used. According to Paul Ramsburg, technical sales specialist at Sika Corp., precasters use a variety of mixers but most are central, stationary, batch-type mixers located at the plant. At computer-controlled central mix plants, initial blending occurs on conveyor belts and mixing occurs on one batch while the next one is simultaneously created. The number and type of mixing cycles in a sequence specify how long it takes to intro
