Gas-added self heat-insulation composite weight-bearing build brick of concrete

Abstract

The invention discloses concrete air entraining self heat preservation compound bearing building block compounded by concrete and air entraining concrete. It includes concrete core block and external insulating layer. The former is set in the building block as bearing material. The air entraining concrete is set at the periphery of the core block as the external insulating layer. The two inorganic materials are made into the building block with of the functions of self heat preservation and bearing which can replace the common clay brick and has the advantages of saving limit land resource, greatly improving wall body useful life, simple processing, convenient construction, compressive strength that over 10MPa.

Description

technical field

[0001] The invention relates to building blocks for building walls, in particular to a concrete aerated self-insulating composite load-bearing block. Background technique

[0002] With the continuous development of my country's construction industry, people's requirements for the environmental protection of building materials are getting higher and higher. As of June 30, 2003, 160 cities in my country have banned the use of solid clay bricks for a limited time. They were originally used in large quantities in walls. The traditional clay bricks can no longer meet the requirements of "energy saving and soil saving", and new wall materials such as concrete porous bricks, gypsum blocks and aerated concrete blocks are constantly emerging. Due to the advantages of high strength, light weight, land saving, energy saving, and waste utilization, concrete small hollow blocks are gradually becoming the dominant wall material to replace solid clay bricks. However, with t...
