Problems solved by technology

Due to the influence of the technical proficiency of the construction personnel and the quality of various raw materials such as cement and sand, the mortar used on the construction site, whether it is masonry mortar, plastering mortar, or ground leveling mortar, often cracks in the plastering mortar of buildings ( Even if the most traditional clay brick wall is plastered with cement mortar, there will be large-scale cracking), resulting in unstable project quality, insufficient strength, and even poor quality, which has become a common problem in construction quality

Abstract

A disclosed environment-friendly waterproof dry-mixed mortar is prepared from the following raw materials in parts by weight: 20-45 parts of Portland cement, 7-16 parts of quartz sand, 11-16 parts of gypsum, 4-8 parts of latex powder, 4-7 parts of wood fiber, 2-6 parts of cellulose ether, 6-10 parts of nanometer silicon dioxide powder, 6-9 parts of hollow alloy bead, 5-9 parts of PP fiber, 10-20 parts of fly ash, 3-7 parts of barium sulfate, 5-8 parts of polymer glue, 15-25 parts of high alumina cement and 3-7 parts of calcium nitrite. The provided environment-friendly waterproof dry-mixed mortar is large in tensile strength, low in cost, thermal-insulating, energy-saving, waterproof, seepage-resisting, reduced in hollow, foaming and cracking phenomena, and strong in adhesive force.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an environment-friendly waterproof dry powder mortar. Background technique [0002] With the improvement of people's living standards, the requirements for building quality are getting higher and higher. Due to the influence of the technical proficiency of the construction personnel and the quality of various raw materials such as cement and sand, the mortar used on the construction site, whether it is masonry mortar, plastering mortar, or ground leveling mortar, often cracks in the plastering mortar of buildings ( Even if the most traditional clay brick wall is plastered with cement mortar, there will be large-scale cracking), resulting in unstable project quality, insufficient strength, and even poor quality, which has become a common problem in construction quality. Thermal insulation mortar and its corresponding anti-cracking mortar are suitable for external th...
