Problems solved by technology

Ready-mixed mortar is of great significance in ensuring the quality of construction projects, realizing civilized construction, and protecting the environment. Therefore, it is necessary to research and develop dry-mixed mortar. Dry-mixed mortar is a construction mix ratio obtained through laboratory design and trial matching verification. In the mixing station, the sand, cementitious material and high-performance mortar additives are mixed evenly after accurate measurement. The thermal performance of the wall meets the current building energy-saving requirements. It has significant advantages in terms of durability and engineering economy. Lightweight masonry mortar is an important part of the self-insulation system of masonry walls. However, the strength of lightweight masonry mortar is low and requires a large amount of cement ratio, which increases the construction cost. cost

Abstract

The invention provides masonry mortar and a preparation process thereof. The concrete comprises the following raw materials in parts by weight: 80-120 parts of cement, 5-16 parts of fly ash, 3-12 parts of thickening powder, 280-320 parts of lightweight aggregate, 480-520 parts of heavy aggregate, 20-30 parts of a water-retaining agent, 3-10 parts of a cementing material, 3-6 parts of an additive and 4-8 parts of a water reducing agent. According to the masonry mortar and the preparation process thereof provided by the invention, the consumption of the cement is reduced, the cost can be saved and the heat conductivity coefficient can be reduced due to the reduction of the consumption of the cement, the mechanical property of the material can be obviously improved by doping the heavy aggregate and the cementing material, and the problems that the strength of light masonry mortar is low, a large amount of cement is required and the cost is low are solved. And the construction cost is increased.

Description

technical field [0001] The invention relates to the field of mortar, in particular to a masonry mortar and a preparation process thereof. Background technique [0002] Most of the mortar is mixed at the construction site. Because there is no strict mixing ratio, the quality is difficult to control, the construction site is dirty and messy, it is not suitable for green construction, and the raw material waste is serious, which has attracted people's attention. To solve the above problems, Only the dry-mixed mortar produced by the factory can play its irreplaceable effect in terms of construction quality and social environmental protection. Ready-mixed mortar is of great significance in ensuring the quality of construction projects, realizing civilized construction, and protecting the environment. Therefore, it is necessary to research and develop dry-mixed mortar. Dry-mixed mortar is a construction mix ratio obtained through laboratory design and trial mix verification. , In...
