Cement-based self-leveling cushion mortar and preparation method thereof
The invention relates to the technical field of flat cushion mortar, and in particular, relates to cement-based self-leveling cushion mortar and a preparation method thereof. The flat cushion mortar is composed of Portland cement, sulphoaluminate cement, siliceous sand, anhydrite, redispersible latex powder and other additives, wherein the proportions of the components comprise 20% of the Portlandcement, 13% of the sulphoaluminate cement, 40% of the siliceous sand, 12% of the anhydrite, 5% of the redispersible latex powder, 6% of other additives. The flat cushion mortar has excellent compressive strength, flexural strength, tensile bonding strength, impact resistance and impermeability and deformation resistance, can realize high leveling precision, and does not have the problems of cracking, dusting, sanding and the like after construction.
本发明涉及平垫层砂浆技术领域，尤其为一种水泥基自流平垫层砂浆及其制备方法，平垫层砂浆包括如下构成成分：硅酸盐水泥、硫铝酸盐水泥、硅质砂、硬石膏、可再分散性乳胶粉以及其他添加剂，其中，各个构成成分的含量所占的比例分别为：硅酸盐水泥：20%；硫铝酸盐水泥：13%；硅质砂：40%；硬石膏：12%；可再分散性乳胶粉：5%；其他添加剂：6%。本发明的平垫层砂浆具有优良的抗压强度、抗折强度、抗拉粘结强度、抗冲击性能以及抗渗抗变形能力，且可实现较高的找平精度，施工后不会出现开裂、起灰、起砂等问题。
