Impermeable cement mortar and preparation method thereof
The invention relates to the field of cement mortar, in particular to impermeable cement mortar and a preparation method thereof. The preparation method comprises the steps that S1, sand is repeatedly screened through the sand screening device, and fine sand is screened down; s2, the screened coarse stone is treated, and the coarse stone is treated into coarse sand; s3, coarse sand, fine sand and cement are mixed with water; and S4, mixing and stirring the coarse sand, the fine sand, the cement and the additive. The impermeable cement mortar prepared by the preparation method of the impermeable cement mortar is prepared from the following raw materials in parts by weight: 1 part of cellulose ether, 2 parts of latex powder, 1 part of a polycarboxylic acid water reducing agent, 1 part of a dry powder defoaming agent, 100 parts of cement, 30 parts of coarse sand, 20 parts of fine sand and 40 parts of water. And coarse stones screened out of sand can be treated, the coarse stones are treated into coarse sand, and waste of sand resources is avoided.
本发明涉及水泥砂浆领域，更具体的说是一种抗渗水泥砂浆及其制备方法。制备方法包括：S1：通过筛砂装置将砂反复进行筛动，将细砂筛下；S2：将筛出的粗石进行处理，将粗石处理为粗砂；S3：将粗砂、细砂与水泥加水混合；S4：将粗砂、细砂、水泥和添加剂混合搅拌。一种抗渗水泥砂浆制备方法所制备的抗渗水泥砂浆，该水泥砂浆由以下份数重量的原料组成：纤维素醚1份、乳胶粉2份、聚羧酸减水剂1份、干粉消泡剂1份、水泥100份、粗砂30份、细砂20份、水40份。可以对砂中筛出的粗石进行处理，将粗石处理为粗砂，避免砂资源的浪费。
