Are Small Aggregates Really Better for Making High-Strength Concrete?

CODEN: CCAGDP

Abstract

It has been stated recently that 10 to 12 mm is the maximum size of aggregates preferable for making high-strength concrete. A discussion of this statement is presented herein, supported by experimental data on eight concretes (normal-strength and high-strength mixes). It is concluded that, in the range of mixes that can be made with the used components—crushed limestone aggregates, Portland cement, silica fume, and superplasticizer, the classical theory still seems to apply: 20 to 25-mm maximum size aggregates lead to better performances and economy than smaller size aggregates.
