研究了再生集料是否膜化处理及替代率不同对砂浆强度的影响。试验结果表明：当膜化处理的再生集料替代率为100%时，其强度与纯天然集料相差不大；而未膜化处理的再生集料替代率为100%时，情况则完全相反。在再生集料的替代率相同的情况下，膜化处理再生砂浆比未处理再生砂浆试块的强度要大。当再生集料替代率为100%时，膜化处理再生砂浆在强度上有明显提高；而再生集料替代率为50%时，强度提高并不明显。

This paper mainly studies on the effects caused by the recycled aggregate film processing and different substitution rate on the strength of cement mortar. The experimental results show that:when the substitution rate of the recycled aggregate film processing is 100%, the strength are similar with the natural aggregate ,but the substitution rate of the recycled aggregate which has not membrane processed is 100%, The situation completely opposite;in the condi-tion which the substitution rates of the recycled aggregate are same , the strength of the recycled mortar film processing is larger than the strength of the recycled mortar blocks which have not membrane processed;when the substitution rate of the recycled aggregate is 100%, the recycled mortar film processing have obviously improved in strength ,and when the substitution rate of the recycled aggregate is 50%, there is not obvious in the increase of the strength .
