Effects of aggregate size on flexural strength and densification of cementitious materials produced by extrusion moulding

摘要

Particle reinforced cementitious mixtures with six maximum sizes of silica sand (NO. 3-8) and various water content ratios were prepared for clarifying the effects of the aggregate size on the flexural strength and the densification under extrusion moulding. The densities of mixtures at each moulding process were measured. NO.6 silica sand of which maximum size was the most similar to standard sand obtained the highest flexural strength.
