Abstract

The invention discloses a cement admixture used for building ready-mixed dry mixed mortar and an application method thereof. The cement admixture comprises the following components: 45-98% of cement, 0-40% of mineral admixture, 0-15% of lime or gypsum and 0.1-5% of additive. 10-50% of cement mixture and 50-90% of sand are mixed, water with 10-20% weight of solid matter is added, stirring to be uniform is carried out, and the cement admixture is used for building construction. Dry ready-mixed mortar is divided into two parts, one part is the cement admixture, and the other part is baked sand. The two parts are separately stored and transported, quantitative cement is added in the scene, and mixing is carried out to obtain the mortar for building. Equipment investment and floor area of a ready-mixed mortar factory are greatly reduced, even the cement admixture is produced by a cement factory without requiring the read-mixed mortar factory, and social investment can be greatly saved.

Description

technical field [0001] The invention relates to a cement mixture mainly used for ready-mixed mortar in the construction industry, and also relates to a method for using the cement mixture. There are two types of ready-mixed mortar for construction: dry-mixed pre-mixed mortar and wet-mixed pre-mixed mortar. The present invention mainly relates to ready-mixed dry-mixed mortar, referred to as dry-mixed mortar. Background technique [0002] Cement mortars for construction are traditionally manufactured and used by mixing the components at the construction site. The disadvantages are: first, serious dust and noise pollution; second, the quality is not easy to control; third, the material stacking occupies a large area. Therefore, more than 90% of developed countries have abandoned this on-site mixing method, and use specialized and commercialized ready-mixed dry-mixed mortar. [0003] The current manufacturing and use methods of commercial dry-mixed mortar are: in the dry-mixe...
