Problems solved by technology

In the field of using fly ash to produce mortar, there are still many problems, such as low early strength resulting in unstable quality
[0006] Modern composite mortar should reduce the use steps. On the one hand, it can reduce construction dust, and at the same time, it can also avoid the phenomenon of easy cracking and breakage caused by the change of the properties of the composite mortar due to the operator's error in the actual application process.

Abstract

The invention provides composite mortar and a manufacturing method thereof, and belongs to the field of production of building materials. In the composited mortar, cement, mineral sand, coal ash and glass beads are taken as aggregates, and carboxymethyl cellulose sodium, wood fibers, gelatine powder, a water-retaining agent, a water reducing agent and a water repellent are taken as additives. The manufacturing method comprises the following steps: first, sequentially putting cement, additives, glass beads and coal ash into a reaction kettle, premixing the mixture for a certain time, putting an obtained substance and mineral sand into a stirrer, stirring the mixture and cooling, so as to obtain the composite mortar. The invention provides the composite mortar and the manufacturing method thereof; the composite mortar has the advantages of being safe and non-toxic and reducing energy consumption, is good in peaceability, crack resistance, thermal insulation and waterproofing, high in strength, corrosion resistance and adhesion, light in weight and convenient in construction, is beneficial to mechanical construction, and has the characteristics of saving working hours and lowering construction cost.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of building material production, in particular to a composite mortar and a manufacturing method thereof. [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 commerci...
