Research of Influences about Different Strength Grade on the Size Effect of Compressive Strength of RPC

摘要

In this paper, the size effect of compressive strength of RPC and influence law about different strength grade on size effect was studied through experimental study and theoretical analysis. The result indicated that the compressive strength of RPC had an obvious size effect phenomenon, and it was minished with the accretion of dimension of test blocks. The size effect coefficients with different size specimen were given, As increasing strength, the size effect phenomenon was clearer. By the theoretical analysis, Bazant compressive strength size effect formula and multiple fractal theory were all suitable for RPC.
