Experimental Study on the Compressive Strength of Nano-Concrete

Article Preview

Abstract:

In order to investigate the effect of Nano-SiO2 on the compressive strength of concrete, the paper studies the effect of different mixing ratios (0%~3%) on the compressive strength, and the effect of age on the compressive strength of nano-concrete. Research shows that the incorporation of Nano-SiO2 increased the compressive strength of concrete: it increases slowly with the mixing ratio 0%~1%; the growth rate is declining when the mixing ratio is 1.5%~3%; the optimal mixing ratio is 1.0~1.5%, which can replace 3.33~10% of cement.
