Impermeable waterproof mortar adopting machine-made sand and preparation process thereof
The invention discloses impermeable waterproof mortar adopting machine-made sand. The impermeable waterproof mortar is prepared from the following raw materials in parts by weight: 150-300 parts of modified machine-made sand, 30-60 parts of cement, 10-20 parts of mineral powder, 5-15 parts of a water reducing agent, 20-40 parts of an additive and 30-50 parts of water. The additive is prepared from the following raw materials in parts by weight: 20-30 parts of water, 5-10 parts of cellulose ether, 1-3 parts of starch ether, 1-3 parts of magnesium aluminum silicate, 2-5 parts of a retarder, 2-4 parts of polysiloxane and 2-5 parts of polycarboxylic acid. In order to solve the problems of poor compactness and workability of finished mortar directly replacing natural sand as a mortar raw material due to high roughness and poor grain shape roundness of the machine-made sand, the machine-made sand is modified, and the workability and compactness of the mortar are effectively enhanced in the mortar preparation process by matching with the specially-made additive.
本发明公开了一种采用机制砂的抗渗防水砂浆，包含以下重量份数的原料制成：改性机制砂150‑300份、水泥30‑60份、矿粉10‑20份、减水剂5‑15份、添加剂20‑40份和水30‑50份。添加剂由包含以下重量份数的原料制成：水20‑30份、纤维素醚5‑10份、淀粉醚1‑3份、硅酸镁铝1‑3份、缓凝剂2‑5份、聚硅氧烷2‑4份、聚羧酸2‑5份。本发明针对机制砂粗糙度高，粒型圆整度差，导致直接替代天然砂作为砂浆原料的成品砂浆密实度以及和易性均较差的问题，对机制砂做了改性处理，并且配合特制的添加剂，在砂浆制备过程中，有效增强砂浆的和易性和密实度。
