A hollow microsphere masonry dedicated thermal insulation mortar and a dedicated surface mortar

Abstract

A hollow microsphere masonry dedicated thermal insulation mortar and a dedicated surface mortar, especially a wall self-insulation system-matching hollow microsphere masonry dedicated thermal insulation mortar and a dedicated surface mortar, relate to a constuction energy-saving technology. The hollow microsphere masonry dedicated thermal insulation mortar comprises, by weight, 20-30% of special cement, 2-6% of coal ash, 20-35% of quartz sand, 5-8% of master batch, 35-45% of hollow microphere, and 3-6% of coarse whiting; and the hollow microsphere masonry dedicated surface mortar comprises, by weight, 28-40% of ordinary Portland cement, 3-6% of coal ash, 7-10% polymer, 40-55% of quartz sand, 10-16% of hollow microsphere, and 1-3% of coarse whiting. With a low heat conductivity coefficient, excellent thermal insulation effect, high compression strength, high bonding strength, low contractibility, environment-friendly and fire-proof properties and notable composite economic results, the wall self-insulation system-matching dedicated thermal insulation mortar and a dedicated surface mortar provided in the invention can be widely popularized and used in wall self-insulation system buildings.

Description

technical field

[0001] The invention relates to a building energy-saving technology, in particular to a special insulating mortar and a special plastering mortar for hollow micro-bead masonry that are matched with a wall self-insulation system. Background technique

[0002] The wall self-insulation system refers to a building wall insulation system that uses energy-saving wall materials and supporting special mortar according to a certain building structure, so that the physical performance indicators such as the thermal performance of the wall meet the corresponding standards.

[0003] Wall self-insulation system can be divided into autoclaved aerated concrete block wall self-insulation system according to the base wall material, energy-saving sintered shale hollow block wall self-insulation system, ceramsite concrete small hollow block wall Self-insulation systems, etc., all use lightweight insulation blocks.

[0004] Ordinary masonry mortar is generally cement mortar or ...
