防水砂浆具有良好的耐候性，耐久性，抗渗性，密实性和极高的粘接力以及极强的防水防腐效果。可耐纯碱生产介质，尿素，硝铵，海水 盐酸及酸碱性盐腐蚀。它与砂普通水泥和特种水泥配制成水泥砂浆，通过调和水泥砂浆浇铸或喷涂，手工涂抹的方法在混凝土及表面形成坚固的防水防腐砂浆层，属刚韧性防水防腐材料。与水泥，砂子混合可使灰浆改性，可用于建筑墙壁及地面的处理及地下工程防水层。

Waterproof mortar has good weather resistance, durability, impermeability, compactness, extremely high adhesion, and strong waterproof and anti-corrosion effects. Can withstand the corrosion of soda ash production media, urea, ammonium nitrate, seawater hydrochloric acid, and acidic and alkaline salts. It is mixed with ordinary cement and special cement to form cement mortar, which is cast or sprayed by blending cement mortar, and manually applied to form a strong waterproof and anti-corrosion mortar layer on the concrete and surface. It is a rigid and tough waterproof and anti-corrosion material. Mixing with cement and sand can modify the mortar, which can be used for the treatment of building walls and floors, as well as underground waterproofing layers.

刚性多层抹面类

Rigid multi-layer plastering type

由水泥加水配制的水泥素浆和由水泥、砂、水配制的水泥砂浆，将其分层交替抹压密实，以使每层毛细孔通道大部分被切断，残留的少量毛细孔也无法形成贯通的渗水孔网。硬化后的防水层具有较高的防水和抗渗性能。

The cement paste prepared by adding water to cement and the cement mortar prepared by cement, sand, and water are layered and alternately pressed and compacted, so that most of the capillary channels in each layer are cut off, and the remaining small number of capillary pores cannot form a continuous permeable pore network. The hardened waterproof layer has high waterproof and anti-seepage performance.

掺防水剂类

Mixing waterproofing agents

在水泥砂浆中掺入各类防水剂以提高砂浆的防水性能，常用的掺防水剂的防水砂浆有氯化物金属类防水砂浆、氯化铁防水砂浆、金属皂类防水砂浆和超早强剂防水砂浆等。

Various waterproofing agents are added to cement mortar to improve its waterproof performance. Commonly used waterproofing agents include chloride metal waterproofing mortar, ferric chloride waterproofing mortar, metal soap waterproofing mortar, and ultra early strength agent waterproofing mortar.

氯化物金属类

Chloride metal class

由氯化钙、氯化铝等金属盐和水按一定比例混合配制的一种淡黄色液体，加入水泥砂浆中与水泥和水起作用。在砂浆凝结硬化过程中生成含水氯硅酸钙、氯铝酸钙等化合物，填塞在砂浆的空隙中以提高砂浆的致密性和防水性。

A light yellow liquid prepared by mixing metal salts such as calcium chloride and aluminum chloride with water in a certain proportion, and added to cement mortar to interact with cement and water. During the solidification and hardening process of mortar, compounds such as hydrated calcium chlorosilicate and calcium chloroaluminate are generated and filled in the gaps of the mortar to improve its density and waterproofing.

氯化铁类用氧化铁皮、盐酸、硫酸铝为主要原料制成的氯化铁防水剂，呈深棕色溶液，主要成分为氯化铁、氯化亚铁及硫酸铝。该防水剂先用水稀释后再加入水泥、砂中搅拌，形成一种防水性能良好的防水砂浆。砂浆中氯化铁与水泥水化时析出的氢氧化钙作用生成氯化钙及氢氧化铁胶体，氯化钙能激发水泥的活性，提高砂浆的强度，而氢氧化铁胶体能降低砂浆的析水性，提高密实性。

Ferric chloride waterproofing agent is mainly made from iron oxide scale, hydrochloric acid, and aluminum sulfate as raw materials. It is a dark brown solution and mainly composed of ferric chloride, ferrous chloride, and aluminum sulfate. The waterproofing agent is first diluted with water and then mixed with cement and sand to form a waterproof mortar with good waterproofing performance. The reaction between ferric chloride in mortar and calcium hydroxide precipitated during cement hydration produces calcium chloride and iron hydroxide colloids. Calcium chloride can stimulate the activity of cement and improve the strength of mortar, while iron hydroxide colloids can reduce the water separation of mortar and improve its compactness.
