Abstract

The invention provides a construction technique for composite mortar and belongs to the technical field of buildings. The construction technique specifically comprises the following steps that a polished wall face is washed firstly, and the wall face is subjected to hair spraying treatment through a wall body interface agent, wherein the wall body interface agent is prepared by blending cement, sand, an additive and water, and the additive comprises carboxymethyl cellulose sodium, wood fibers, flexible rubber powder, a water-retaining agent, a water reducing agent and a water repellent; then the wall body surface is subjected to anchoring; and finally the wall face is subjected to composite mortar layered spraying through a dedicated mortar spray gun, and water spraying maintenance is noticed, wherein the composite mortar comprises cement, mineral sand, prefabricated coal powder ash, glazed hollow beads and an additive. According to the construction technique for the composite mortar, the anti-cracking and waterproof effects of the composite mortar can be improved, the used composite mortar has the advantages of being safe and innoxious and has the characteristics of being good in workability and capable of achieving the anti-cracking, heat-insulation, heat-preservation, waterproof, high-strength and corrosion-resistance effects, and building cost can further be reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of building material construction, in particular to a construction technology of composite mortar. [0003] 【technical background】 [0004] Composite mortar is high-strength cement mortar mixed with modified epoxy emulsion or other modified copolymer emulsion, also known as polymer mortar. For example, composite mortar suitable for load-bearing structures should be able to improve its own physical and mechanical properties. It should also significantly improve its ability to anchor steel bars and bond concrete. The production of composite mortar meets the needs of national building environmental protection and green construction production. It should be safe and non-toxic, reduce energy consumption, reduce dust, and facilitate construction, which is conducive to mechanized construction, saving man-hours and reducing construction costs. On-site manual mixing of mortar and prefabricated commercial con...
