Abstract:The specific surface of aggregate for concrete was measured by the water permeability method, and its effect on the consistency of concrete was ex-amined. A wide range of gradings, including extreme gap-gradings, was tested. The range of mix proportions and aggregate normally used in practice was included. Results show that the specific surface affects the consistency markedly. Aggregate gradings of the same specific surface, for practical purposes, have the same concrete making properties. However, as the specific surface of the aggregate increases, consist(ency becomes stiffer, other factors, being equal.
