防水砂漿具有良好的耐候性，耐久性，抗滲性，密實性和極高的粘接力以及極強的防水防腐效果。可耐純堿生產介質，尿素，硝銨，海水 鹽酸及酸堿性鹽腐蝕。它與砂普通水泥和特種水泥配制成水泥砂漿，通過調和水泥砂漿澆鑄或噴涂，手工涂抹的方法在混凝土及表面形成堅固的防水防腐砂漿層，屬剛韌性防水防腐材料。與水泥，砂子混合可使灰漿改性，可用于建筑墻壁及地面的處理及地下工程防水層。

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.

剛性多層抹面類

Rigid multi-layer plastering type

由水泥加水配制的水泥素漿和由水泥、砂、水配制的水泥砂漿，將其分層交替抹壓密實，以使每層毛細孔通道大部分被切斷，殘留的少量毛細孔也無法形成貫通的滲水孔網。硬化后的防水層具有較高的防水和抗滲性能。

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.

摻防水劑類

Mixing waterproofing agents

在水泥砂漿中摻入各類防水劑以提高砂漿的防水性能，常用的摻防水劑的防水砂漿有氯化物金屬類防水砂漿、氯化鐵防水砂漿、金屬皂類防水砂漿和超早強劑防水砂漿等。

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.

氯化物金屬類

Chloride metal class

由氯化鈣、氯化鋁等金屬鹽和水按一定比例混合配制的一種淡黃色液體，加入水泥砂漿中與水泥和水起作用。在砂漿凝結硬化過程中生成含水氯硅酸鈣、氯鋁酸鈣等化合物，填塞在砂漿的空隙中以提高砂漿的致密性和防水性。

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.

氯化鐵類用氧化鐵皮、鹽酸、硫酸鋁為主要原料制成的氯化鐵防水劑，呈深棕色溶液，主要成分為氯化鐵、氯化亞鐵及硫酸鋁。該防水劑先用水稀釋后再加入水泥、砂中攪拌，形成一種防水性能良好的防水砂漿。砂漿中氯化鐵與水泥水化時析出的氫氧化鈣作用生成氯化鈣及氫氧化鐵膠體，氯化鈣能激發水泥的活性，提高砂漿的強度，而氫氧化鐵膠體能降低砂漿的析水性，提高密實性。

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.
