Abstract

The invention relates to waterproof and crack-resistant mortar for buildings prepared from steel slag. The waterproof and crack-resistant mortar comprises the following components in weight percentage: 55-80% of steel slag with granularity of not more than 4.75 mm, 15-40% of silicates cements, 0.5-5% of acrylic acid gelatine powder, 0.05-5% of water-retaining agent, 0.1-1.0% of wood fiber, 0-0.5% of water reducing agent and 0-0.5% of organosilicon water repellent. Compared with the prior art, the waterproof and crack-resistant dry-mixed mortar for buildings is prepared from the steel slag which partially or totally replaces natural sand, thereby protecting natural ecology and environment, comprehensively utilizing the steel slag and improving additional values thereof and having the advantages of high waterproof efficiency, overall crack resistance, excellent impact resistance and flexibility, favorable construction and workability, energy saving, consumption reduction, stable performance and simple construction; and the mortar does not contain poisonous and harmful substances.

Description

technical field [0001] The invention relates to building mortar, in particular to waterproof and crack-resistant building mortar prepared from steel slag. Background technique [0002] With the development of the iron and steel industry, the amount of steel slag is increasing day by day. If it is discarded, the pollution to the environment will be more serious. With the increasing emphasis on environmental protection in the world, the research approach of turning waste into wealth is extremely important. In the early days, due to the long-term abandonment of steel slag, it piled up into slag mountains, which not only occupied a large amount of land, but also caused serious environmental pollution. Therefore, how to effectively use steel slag to bring economic benefits without polluting the environment has become a The important direction of the current steel slag recycling. If steel slag is used as a base material in construction projects, it not only has abundant sources ...
