Moisture Control in Concrete Production Agg-Net
2021-10-22 The final water added during the mixing stage may be adjusted based on the aggregate moisture content to achieve an accurate water/cement ratio and consistent slump. For optimum performance, however, separate control of moisture and water addition in the mixer is recommended. Problems associated with variations in moisture

GRADATION OF AGGREGATE FOR CONCRETE BLOCK -
for 8 X 8 X 16 inch. Concrete block, of 37.5% core space, made on a power tamping block machine at a yield of 21.0 to 22.4 block per bag of cement. The aggregate was blended from fine (No. 4 to 0) and coarse (3/8 inch to No. 4) materials in proportions to yield the desired fineness modulus. It should be noted that the strengths given in Fig. 2

What is a Concrete Aggregate? (with pictures) - Info Bloom
Concrete aggregate is more durable and water resistant than conventional concrete. The texture of the aggregate is also a consideration. Coarse, porous materials will suck up water during the mixing process, requiring the addition of more water to compensate. This in turn throws off the water to concrete
