Portland cement-based mortar and preparation process thereof
The invention discloses Portland cement-based mortar and a preparation process thereof. The Portland cement-based mortar is prepared from the following raw materials in parts by weight: 28.563-32.99%of Portland cement, 2.361-9.324% of industrial byproduct stone powder, 50% of fine sand, 12.8-14.8% of water and 0.027-0.072% of a water reducing agent. The preparation method comprises the followingsteps: S1, weighing raw materials in parts by weight, firstly putting cement and by-product stone powder in the raw materials into a stirrer for dry stirring, and then putting fine sand for uniform stirring; S2, adding the weighed polycarboxylate superplasticizer into the weighed water, and conducting stirring to dissolve the polycarboxylate superplasticizer; S3, adding the solution prepared in the step S2 into a stirrer, and conducting uniform stirring; and S4, after stirring is finished, conducting die filling and vibration molding, moving the material to a curing box for curing, and then conducting demolding to obtain a finished product. The industrial by-product stone powder is used for replacing part of silicate cement paste, the usage amount of the industrial by-product stone powderis controlled to account for 2.361-9.324% of the total mass of the mortar, the water-binder ratio can be reduced, and the overall mechanical strength of a cement-based material matrix is improved.
本发明公开一种硅酸盐水泥基砂浆及其制备工艺，包括以下原料的重量份组成：硅酸盐水泥28.563‑32.99％、工业副产石粉2.361‑9.324％、细沙50％、水12.8‑14.8％、减水剂0.027‑0.072％。包括以下步骤：S1、原料按照重量份称取，先将原料中的水泥、副产石粉放入搅拌机中干搅拌，再放入细沙搅拌至均匀；S2、将所称的聚羧酸减水剂加入称量好的水中，搅拌使其溶解；S3、将S2所制溶液加入搅拌机中，搅拌至均匀；S4、搅拌结束后，装模并振捣成型，移放至养护箱养护后进行脱模，得到成品。通过使用工业副产石粉替代部分硅酸盐水泥浆体，控制其使用量占砂浆总质量的2.361‑9.324％，可以降低水胶比，提升水泥基材料基体的整体力学强度。
