Building mortar and preparation process thereof

Abstract

The invention relates to the technical field of building construction materials, in particular to a building mortar and a preparation process thereof. The building mortar comprises the following ingredients in weight ratios: 150-155 parts of sand, 20-25 parts of cement, 25-30 parts of water, 10-12 parts of ceramic particles, 8-10 parts of glass particles, 10-12 parts of gypsum and 9-12 parts of adhesive; wherein the maximum particle size of the ceramic particles and the glass particles is less than 300 mum; the gypsum is floor gypsum calcined at 800 DEG C. The sound insulation effect of the building mortar is very good, and the mechanical properties of the mortar is also better, some indicators have increased, the mortar is suitable for promotion. Gypsum is added into mortar after calcinedat high temperature, which further increases the strength, wear resistance and water resistance of mortar. And gypsum also has good sound insulation, heat insulation and fire performance, further improve the sound insulation, heat insulation and fire performance of mortar.

Description

technical field [0001] The invention relates to the technical field of building construction materials, in particular to building mortar and its preparation process. Background technique [0002] China is a populous country with a relatively high population density, especially in some big cities, where the population density is higher, so most people have limited living space; at present, the sound insulation effect of many buildings is not good enough, especially for impact sound. , pedestrians walking, running and jumping in the corridors or on the upper floors have a relatively large impact on the residents, causing a certain amount of noise pollution. [0003] In order to reduce noise, some will lay carpets or lay elastic surface materials on the corridors and floors. Carpeting or laying a resilient surface material can absorb some of the impact and reduce noise; however, carpet cleaning is troublesome, and for those who prefer tile floors or various types of floors, re...

Problems solved by technology

However, due to the addition of closed-cell expanded perlite, closed-cell expanded perlite tends to produce resistance in the mortar and has poor workability, which makes it difficult to distribute evenly in the mortar, easily causing stress concentration, causing hollowing, cracking, and reducing Mechanical Properties of Mortar
