Abstract

High-strength cement paste with higher brittleness and polymer cement concrete with lower brittleness are selected to compare their size effect on strength. Tentative works performed in experiment and numerical analysis are presented in this paper. It is shown that brittleness affects the size effect on strength of concrete. According to experimental and numerical results, there is a possibility that at laboratory scale a high- strength concrete with high brittleness displays higher strength than a normal concrete with low brittleness, nevertheless, the high-strength concrete displays lower strength than the normal concrete at larger scale.
