Abstract

The invention provides a high-performance dry-mixed mortar. The high-performance dry-mixed mortar is prepared from the components in parts by weight: 110-130 parts of PO42.5 cement, 70-90 parts of stone powder, 800-820 parts of sand and 0.4-0.6 part of an admixture. The high-performance dry-mixed mortar has the following beneficial effects that the characteristics of water retention, thickening and performance changing can be achieved by effectively utilizing the admixture, the peaceability and working performance of the mortar are improved, the working and production efficiency of construction personnel is improved, and meanwhile the problems of prone cracking, hollowing and surface falling off of a general mortar are solved.

Description

【Technical field】 [0001] The invention relates to the technical field of building construction materials, in particular to a high-performance dry-mixed mortar. 【Background technique】 [0002] At present, the construction performance of dry-mixed mortar is generally poor in China. Therefore, there is an urgent need for a green, environmentally friendly and energy-saving material that can prevent dry-mixed mortar (plastering) from cracking and hollowing after construction. 【Content of invention】 [0003] The invention discloses a high-performance dry-mixed mortar, so as to solve the problems involved in the background technology. [0004] To achieve the above object, the technical solution of the present invention is: [0005] A high-performance dry-mixed mortar comprises 110-130 parts of PO42.5 cement, 70-90 parts of stone powder, 800-820 parts of sand and 0.4-0.6 parts of admixture by weight. [0006] Preferably, the PO42.5 cement accounts for 120 parts, the stone powder...
