摘　　要：针对废旧橡胶微粒在外保温用粘结砂浆的应用进行研究,探索了在不同粒径下,助剂法生产的橡胶微粒掺量对粘结砂浆粘结强度(原强度、耐水粘结强度)的影响规律。研究结果表明,废旧橡胶颗粒在外保温用粘结砂浆中的应用具有可行性;在相同粒径下,随着橡胶微粒掺量的增加,粘结强度降低;在粘结砂浆性能满足标准要求的前提下,随着橡胶微粒粒径的增大粘结砂浆中橡胶微粒允许掺入量越多。Aiming at the research on application of waste rubber particles exterior insulation binding mortar, the influence rule of rubber particles produced by accessory ingredient method to the bond strength （original strength, water-resistant bond strength） of binding mortar was studied on different dosages at different size. The results show that it is feasible for the application of waste rubber particles in exterior insulation binding mortar; under the same size, the bond strength decreases with the increasing of rubber particles dosage： under the precondition that the performance of the binding mortar can meet the standard, the bigger the grain size of rubber particles, the more dosage allowed to be mixed in the binding mortar.
