高强度混凝土试验研究

Experimental research on high-strength concrete

高强度混凝土C80在建筑工程中的应用问题极为重要。为了使设计及施工单位正常设计及使用较高强度等级混凝土,扩大高强度等级混凝土C80在建筑工程中的应用,通过不同强度等级水泥、不同粉煤灰掺量、不同品种外加剂的混凝土进行试配试验,测定混凝土强度的变化过程,对水泥强度等级、粉煤灰掺量、外加剂掺量三者之间的相互关系进行了对比分析,得出了高强度等级混凝土C80在混凝土工程中应用的参考配合比。

High-strength concrete（HSC） C80 plays an important role in construction engineering, and the research has been done in order to help construction companies with correctly using HSC and widening its application. Authors measured the strength variation of concrete which was obtained from experiments using different mixtures of cement, fly-ash and chemical admixture. Then, the relationships among concrete strength grade, fly-ash and chemical admixture were compared and analyzed and a proper mixed ratio of HSC C80 was made.
