Batching, Mixing, Transporting, and Handling Concrete ...
Batching, Mixing, Transporting, and Handling Concrete percentages of accuracy: cementitious material ±1%, aggregates ± 2%, water ±1%, and admixtures ± 3%. Equipment should be capable of measuring quantities within these tolerances for the smallest batch regularly used as well as for larger batches (Fig. 101). The
