Study on Improving the Durability of Cement Concrete for Bridge Mixing With Nano Material by Experiment

摘要

In the essay, that cement concrete mixed with Nano-SiO_2, the cement concrete mixing with Nano scale fly-ash and the cement concrete mixing with Nano-SiO_2 have been tested on preventing the adverse effect of sulfates shows that the cement concrete mixing with Nano-SiO_2 improves the performance of the concrete to prevent the adverse effect of sulfates.
