摘要
采用碳化深度测量、SEM、XRD等手段,在特定的环境下研究了不同等级砂加气混凝土的碳化性能和力学性能。结果表明:由于砂加气混凝土水化生成的托贝莫来石逐渐转变为方解石,砂加气混凝土的抗压强度随着碳化深度的增加而明显下降。
The carbonation performance and mechanical properties of different grades of sand aerated concrete were studied under specific conditions by means of depth measurement,SEM and XRD.The results show that the compressive strength of sand aerated concrete decreases obviously with the increase of carbonation depth because of the tobermorite formed by hydration of sand aerated concrete gradually transforms into calcite.
