Concrete foaming agent

Abstract

A concrete foaming agent is prepared from the following raw materials in parts by weight: 3-8 parts of konjac glucomannan, 7-9 parts of malt dextrin, 4-8 parts of limestone powder, 8-11 parts of modified diatomite, 9-15 parts of polyacrylic acid resin, 4-9 parts of polyethylene glycol, 5-10 parts of sulphoaluminate cement clinker, 4-9 parts of anhydrite, 4-8 parts of methyl methacrylate, 3-11 parts of mica powder, 6-13 parts of hydroxyethyl methyl cellulose, 6-8 parts of borax, 1-5 parts of sodium alkyl benzene sulfonate and 4-7 parts of sodium methylene dinaphthalene sulfonate. The beneficial effects of the concrete foaming agent are that, the concrete foaming agent can effectively increase the foaming height, and has good foam stability and low cost.

Description

technical field [0001] The invention relates to a concrete foaming agent. Background technique [0002] With the improvement of the country's requirements for building energy-saving materials, foamed concrete has received more and more attention. Foamed concrete is made of cement, lime, fly ash, sand and admixtures, etc. A "tight cell" lightweight building material containing a large number of closed pores. The application of cement foaming agent in our country has a history of more than 50 years. In the early 1950s, my country developed two foaming agents, rosin soap and rosin thermal polymer, and used them in mortar and foamed concrete. With the rise of my country's surface active industry, synthetic surfactant-type foaming agents began to be used, and replaced a considerable part of rosin soap and rosin thermopolymer, but the existing foaming agents can not meet the requirements of use, there are various kind of defect.
