掺粉煤灰混凝土强度增长与龄期关系的试验研究

The testing researches on age strength relation of concrete adulterated with fly ash

粉煤灰掺入混凝土中取代部分水泥,不仅可以降低混凝土的成本,还可以改善混凝土的物理力学性能及耐久性。本文针对掺粉煤灰普通水泥配制的混凝土,对其各龄期强度间的关系进行了研究。通过回归分析得出掺粉煤灰普通水泥混凝土的强度增长与龄期的关系式。

Replacing part of cement with fly ash in the mixture of concrete, we can reduce the concrete's cost, improve its physical mechanics properties and its durability. Studying on age strength relation of the mixed fly ash concrete by using monadic linear regression, we can find its age strength relation.
