活化剂提高粉煤灰混凝土强度的试验研究

Experimental Investigation on Strength of Fly Ash Concrete be Raised by Use of the Activator

本文介绍了使用活化剂提高粉煤灰混凝土强度的试验及其分析。实验中使用的粉煤灰是Ⅰ级灰 ,在混凝土中的掺量高达 5 0 %和 60 % .试验证明活化剂能够显著提高粉煤灰混凝土的早期强度和后期强度。

The test and its analysis of which the strength of pulverized coal fly ash (PFA)concrete be raised by use of the activator are introduced in this paper.The PFA to be used is I grade ash,its doaage in the concrete is high as 50% and 60%.The test has proved that the activator can raise markedly the early age strength and late age strength of the PFA concrete.〔
