摘要
本文用快速碳化试验方法测定了不同养护龄期的普通水泥砂浆试件与掺粉煤灰的砂浆试件的碳化深度.在此基础上研究了养护龄期对掺粉煤灰混凝土碳化速率的影响;分析了试件强度与碳化速率的关系;并对碳化作用机理作了讨论.
In the present paper,the carbonation depth of cement mortars with and with- out fly ash was measured by accelerating carbonation test method.The influencэ of curing time on the carbonation depth of fly ash concrete was studied.The cor- relation of the compressive strength to the carbonation depth was analyzed and the mechanism of carbonation was also discussed.
