钢渣粉对混凝土抗碳化性能的影响

摘要

研究钢渣粉对混凝土抗碳化性能的影响，结果显示：混凝土碳化初期的碳化速度较快，随碳化时间延长，碳化速度趋缓；掺入钢渣粉可降低混凝土碳化后期的碳化深度；碳化后混凝土抗压强度有所提高；掺入钢渣粉后强度提高幅度减小。%In this paper,the effect of steel slag powder on the carbonation resistance of concrete was studied. The results show:the rate of concrete carbonization is faster in early age and slow down with carbonation time;The mixed with steel slag powder can reduce the depth of carbonation of concrete late;Carbonized can im-prove the compressive strength of concrete and improvement rate reduces when steel slag are introduced.
