Polystyrene foam aggregate concrete insulation building block

Abstract

The invention belongs to the field of concrete insulation building block materials, and specifically provides a polystyrene foam aggregate concrete insulation building block. The building block consists of polystyrene foam aggregate, slurry and a foaming agent, wherein the mass ratio of the polystyrene foam aggregate to the slurry to the foaming agent is (0.004-0.01): 1.0: (0.008-0.015); in the slurry, the mass ratio of water to cement to river sand or coal ash to early strength agent is equal to (0.5-0.55): 1.0: (3.0-4.0): (0.01-0.02). The polystyrene foam aggregate concrete insulation building block gives consideration to the relationship of the building block strength, a production technology and the production cost, the compressive strength of the building block is more than two times than those of like products, but the cost of the building block is 20% less than that of the like products.

Description

technical field [0001] The invention belongs to the field of concrete thermal insulation masonry materials, and specifically provides a polystyrene foam aggregate concrete thermal insulation block. Background technique [0002] Foamed concrete originated from the building insulation in cold Nordic countries. For decades, its main application market has always been building insulation. Although the application volume in other fields has increased in recent years, building insulation has always been dominant. Due to the increasingly obvious trend of world energy depletion, countries all over the world have paid attention to building energy conservation, which has created conditions for the development of foam concrete. It can be said that the worldwide foam concrete heat is the product of building energy conservation. The Chinese government has made building energy conservation a basic national policy, and the efforts to promote it have been increasing year by year, which de...

AI Technical Summary

Problems solved by technology

[0004] A polystyrene foam insulation brick disclosed in patent application No. 95112073 has its main technical advantage in its thermal insulation performance, which is difficult to meet the required strength of masonry; a light aggregate foam concrete block disclosed in patent application No. 200810210615.1 and its The manufacturing method requires the use of steam autoclave curing, which takes a long time to cure and is difficult to produce in large quantities

[0005] To sum up, the main disadvantage of the prior art is that it is difficult to take into account the relationship between masonry strength, manufacturing process and production cost

Specifically, the cost of high strength (compressive strength above 3Mpa) is high, and the process is relatively complicated, it is difficult to produce in large quantities, its market competitiveness declines, and its promotion is naturally limited
