Mortar and preparation method thereof
The invention relates to the technical field of building materials, in particular to mortar and a preparation method thereof.The preparation method comprises the following steps that fine powder with the particle size smaller than 80 micrometers is screened out of recycled aggregate, and then prefabricated recycled aggregate is obtained; uniformly stirring and mixing the hyperdispersant, the flexible anti-cracking agent, the cellulose ether, the air entraining agent and the retarder to obtain a first mixture; the first mixture, the cement and the prefabricated recycled aggregate are stirred and mixed evenly to obtain the mortar, the preparation process is simple, the mixing amount of fine powder with the particle size smaller than 80 micrometers in the recycled aggregate is reduced as much as possible, and meanwhile the problem that the mortar is prone to cracking after being cured is avoided as much as possible.
本申请涉及建筑材料技术领域，尤其是涉及一种砂浆及其制备方法，包括以下步骤：将小于80μm粒径的细粉从再生骨料中筛分出来后得到预制再生骨料；将超分散剂、柔性抗裂剂、纤维素醚、引气剂和缓凝剂搅拌混合均匀得到第一混合料；将第一混合料、水泥和预制再生骨料搅拌混合均匀得到砂浆，其制备工艺简单，实现尽量减少小于80μm粒径的细粉在再生骨料中的掺量的同时尽量避免砂浆固化后易开裂的问题出现。
