Abstract:
The acid rain's condition in Guangdong is simulated, and considering the varieties and content of mineral admixtures, the performance changes of bridge C50 high strength concrete are studied under the corrosion of acid rain by periodical immersion and spraying method. The results show that, from the performance of anti-corrosion ability of C50 high strength concrete, the effect of double mixed mineral admixtures is better than single doped fly ash or slag, and the best experimental dosage is 25% by double mixed with fly ash and slag.
