一种具有低弹性模量的水泥沥青砂浆材料
摘要：
本发明涉及一种城际高速铁路、城市地铁用高减震性能的CA砂浆材料，特别是一种具有低弹性模量的CA砂浆材料，它由水泥、沥青乳液、砂、膨胀剂、消泡剂、引气剂、减水剂、铝粉、橡胶颗粒原料混合搅拌而成，各原材料所占质量份为：水泥：1，乳化沥青：0.4-2.5，砂0.01-3.5，膨胀剂：0.01-0.4，消泡剂：0-0.01，引气剂：0.00003-0.003，减水剂：0.001-0.1，水：0-0.8，铝粉：0.00001-0.001，橡胶颗粒：0.01-0.4。所述橡胶颗粒为经过界面处理剂处理后的橡胶，粒径0.5-3毫米。本发明提供的低弹性模量CA砂浆材料能使CA砂浆弹性模量降低，提高减隔震作用。
摘要（英）：

The invention relates to a CA mortar material with high shock absorption performance for intercity high-speed railways and city subways, in particular to a CA mortar material with low elastic modulus, which is prepared by mixing and stirring the following raw materials in portions by weight: 1 portion of cement, 0.4-2.5 portions of emulsified asphalt, 0.01-3.5 portions of sands, 0.01-0.4 portion of expanding agent, 0-0.01 portion of defoaming agent, 0.00003-0.003 portion of air entraining agent, 0.001-0.1 portion of water reducing agent, 0-0.8 portion of water, 0.00001-0.001 portion of aluminum powder and 0.01-0.4 portion of rubber particle, wherein the rubber particle is rubber treated by an interfacial treatment agent, and the particle diameter is 0.5-3 millimeters. The CA mortar material with low elastic modulus, which is provided by the invention, can reduce the elastic modulus of the CA mortar and improve shock absorption and shock insulation effects.
