海砂中贝壳含量对混凝土拌合物性能及抗压强度影响的试验研究

本文主要通过配制不同贝壳含量的淡化海砂配制成混凝土,测试其拌合物性能,以分析贝壳含量对混凝土拌合物性能和抗压强度的影响,结果表明,少量的贝壳含量对于混凝土拌合物性能及抗压强度是有利的,但当贝壳含量超过8%之后,其性能急剧下降。

Influence of Shell Content On Working Performance and Mechanical characteristic of Concrete Mixture

This article studied the influence of shell sand content on working performance and mechanical characteristic of concrete mixture by testing the concretes made with sea sands of different shell contents. The result shows that a small amount of shell content is advanta- geous to working performance and mechanical characteristic of concrete mixture. When the shell content exceeds the 8 percent, working performance and mechanical characteristic of concrete mixture decreases sharply.
