Coarse Aggregate Testing For Concrete

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE .

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE .

smaller sized coarse aggregate produces higher strengths for a given watertocement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make highstrength concrete, it is easier to do so with coarse aggregates below mm (Y, in.) (ACI 36395).

Why do we need to dry the aggregate (coarse) before ...

Answer: because aggregate is generally not dried, therefore the aggregate moisture content will affect the water content (and thus the w/c also) of the produced PCC and the water content also affects aggregate proportioning (because it contributes to aggregate weight). In general, there are four ...
