一种抗冻型水泥沥青砂浆及其配制方法
摘要：
本发明公开了一种抗冻型CA砂浆及其配制方法，属于建筑材料及其配制工艺技术领域，含有水泥、砂、乳化沥青和水，还含有混合料、消泡剂、引气剂和铝粉，所述原料按一定配比和一定投放顺序配制而成并且制成的CA砂浆还要达到相应的技术指标要求；本发明的抗冻型CA砂浆用于轨道板和底座基础之间的接合，可以使得轨道板和底座基础严密接合，具有调整和缓冲作用，同时使得轨道具有一定的弹性，从而可增强轨道的使用寿命；又由于原料中含有消泡剂和引气剂，使砂浆具备一定的微小气泡，该砂浆又具有抗冻性能，可以用于寒冷地带。
摘要（英）：

The present invention discloses a kind of antifreezing CA mortar and its compounding process and belongs to the field of building material technology. The antifreezing CA mortar contains cement, emulsified asphalt, sand and water as well as mixing material, defoaming agent, air entraining agent and aluminum powder, and is compounded through mixing the materials in certain weight proportion to reach corresponding technological indexes. The antifreezing CA mortar is used in jointing track plate and the pedestal, can reach tight jointing and has certain regulating and buffering effect. It can endow track with certain elasticity and long service life, and has antifreezing performance for use in warming area.
