Light-weight dry-mixed masonry mortar

Abstract

The invention discloses light-weight dry-mixed masonry mortar. The light-weight dry-mixed masonry mortar comprises the following components in percentage by weight: 200 to 300 percent of concrete, 80 to 120 percent of pulverized fuel ash, 400 to 1,400 percent of aerated concrete gains, 80 to 140 percent of vitrified beads, 0.8 to 1.6 percent of PP fibers, 2 to 12 percent of latex powder, and 3 to 15 percent of compound air entraining agent. The mortar has the advantages of avoiding field stirring and mixing, reducing construction dusts and noise pollution and reducing space occupation, along with precise mixing ratio, small concrete use amount, low cost, only need of adding water and mixing uniformly during construction, small material consumption and waste, convenient storage and transport and use, high binding strength, low shrinkage, high freezing resistance durability, low conductivity, good heat preservation, good workability, convenient construction, and the like; by substituting the aerated concrete gains for sand and using the pulverized fuel ash, the light-weight dry-mixed masonry mortar has the characteristics of industrial waste utilization, environmental protection, and low cost.

Description

technical field [0001] The invention relates to a masonry mortar, in particular to a lightweight dry powder masonry mortar. Background technique [0002] Building energy saving has been paid more and more attention by countries all over the world. The main way is to use thermal insulation materials. New wall materials are more and more widely used, and solid clay bricks will gradually withdraw from the stage of history. Although the variety of wall materials has changed, the building mortar that plays a key role in cementing, decoration, and protection of wall materials still uses the supporting material of solid clay bricks—traditional on-site mixing mortar. On the one hand, the traditional mortar production method is on-site mixing during construction. Due to the uncertainty of various factors such as personnel quality, equipment tools, measurement methods, climatic conditions, material sources, etc., there are often random proportions, uneven mixing, and measurement. It ...

Problems solved by technology

On the one hand, the traditional mortar production method is on-site mixing during construction. Due to the uncertainty of various factors such as personnel quality, equipment tools, measurement methods, climate conditions, and material sources, random proportioning, uneven mixing, and measurement Inaccurate and other problems, it is difficult to guarantee the quality of the mortar, the functional properties of the mortar, such as cohesiveness, water retention, deformation, flexibility, impermeability, air content to improve workability, hardness, etc. The effect of bonding the wall materials together does not give the wall materials a better use function
