Abstract

The invention discloses high-performance corrosion-resistant dry-mixed waterproof mortar. The high-performance corrosion-resistant dry-mixed waterproof mortar is prepared from the following raw materials in parts by weight: 60-70 parts of cement, 35-45 parts of mineral powder, 10-30 parts of coal ash, 300-500 parts of regenerated fine aggregates and 5-10 parts of a compounded additive, wherein the compounded additive is prepared from the following raw materials in parts by weight: 40-60 parts of coal ash, 5-7 parts of a water repellent, 40-50 parts of an expanding agent, 2-5 parts of an air-entraining and water-reducing agent, 2-4 parts of anti-crack short fiber and 2-10 parts of a water-retaining thickening agent. By virtue of a dry-mixing form, the high-performance corrosion-resistant dry-mixed waterproof mortar is convenient to use, and the sulfate corrosion can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to a high-performance corrosion-resistant dry-mixed waterproof mortar. Background technique [0002] At present, with the rapid economic development and the continuous expansion of urban construction scale, there are more and more infrastructure construction and various industrial buildings, and the construction environment is becoming more and more complex. Especially ports, bridges, and various civil and industrial buildings located in coastal areas are eroded by saline-alkali chemicals, resulting in a greatly reduced safe lifespan. How to greatly extend the life of the building without increasing the construction process during the construction process will have huge economic and social benefits. [0003] In order to reduce the environmental pollution caused by urban construction, the state has clearly requested that in the process of building construction, it is forbidden to fee...
