| 摘 要： | 为了更有效地处理及再利用废橡胶和废弃混凝土,对橡胶粉再生砂浆的力学性能进行了试验研究.选取60目精细胶粉与I级粉煤灰直接掺入到再生砂浆中,通过与素再生砂浆、普通砂浆的对比,研究了其对再生砂浆抗折强度与抗压强度的影响,并探讨了橡胶粉和粉煤灰的作用机理.结果表明:橡胶粉掺量为4%、粉煤灰掺量为15%时,有利于改善再生砂浆的力学性能.

| Abstract: | Presenting an experiment study on mechanical properties of rubber recycled aggregate mortar, adding 60 mesh rubber power and first grade fly ash directly to recycle aggregate mortar, the effect of compressive strength and flexural strength was investigated and discussed, and function mechanism are compared with plain recycled mortar and normal mortar. It is found that the mechanical properties of recycled aggregate mortar are enhanced as the proportion of rubber powder 4% and fly ash 15%. |
