高掺量粉煤灰混凝土的碳化及防止途径

Carbonation and ways of preventing carbonation of high-volume fly ash concrete

对比试验表明 ,高掺量粉煤灰混凝土比普通混凝土的碳化速度明显加快 ,对其机理进行了较详细的分析 。

It is shown that the rate of carbonation of high volume fly ash concrete is obviously faster than OPC concrete and the mechanisme of the rate of carbonation fast of high volume fly ash concrete were analyzed.The feasible technical approaches for high volume fly ash concrete to prevent carbonation were enumerated.
