Abstract
The invention relates to a composition for preparing a dry-mixed mortar. The composition comprises a gel material, converter slag, latex powder and a water reducer. In the composition for the dry-mixed mortar, the use proportion of the converter slag is very high, and desulfurized gypsum and coal ash are also added, so the production cost and environmental pollution are reduced; added additives comprise the latex powder and the water reducer, so the quality of the dry-mixed mortar is stable, and the use effect of the dry-mixed mortar is good.
Description
technical field [0001] The invention relates to a composition for preparing dry-mixed mortar with converter slag as aggregate used in the construction field. Background technique [0002] Dry-mixed mortar is a dry granular mixture used in the construction field, which can be used directly after being mixed with water at the construction site. Dry-mixed mortar includes interior and exterior wall plastering mortar, wall masonry mortar, and ground mortar. In the prior art, dry-mixed mortar is composed of aggregates, cementitious materials and additives, wherein the aggregates are usually quartz sand, river sand, etc.; the cementitious material is cement; the additives are mainly composed of polymers. Although the dry-mixed mortar made of the above materials has the functions of bonding, lining, protection and decoration, due to the limited resources such as quartz sand and river sand, and the price is relatively high, at the same time, only relatively high-priced cement is use...
