Problems solved by technology

At present, the main raw materials of cement concrete blocks are cement and sand. Since the specific gravity of sand is relatively large, and the cement concrete blocks made of sand are relatively dense, the cement concrete blocks made of sand are relatively dense. The specific gravity is relatively large, and this cement concrete block has certain limitations in terms of sound insulation, heat insulation, and fire protection.

Abstract

This invention discloses a kind of porous concrete building blocks composed of cement, coal ash, blister and additive agent etc. The specific weight of the building block is lighter than the block made up of sand and stones. This invention usually have a large number of small air bubbles in the processing which can form many tiny air holes, so it is better in fireproofing, sound insulation and heat insulation. Besides, its main material is wasted flyash, solving the problem of disposing the flyash and making full use of it, so it is very helpful to protect environment.

Description

technical field [0001] The invention relates to a cement concrete block, in particular to a cement concrete block used as a building wall material. Background technique [0002] Because cement concrete blocks can protect land resources and ecological environment, and do not need to be fired, they are gradually replacing red bricks as a building wall material, and they have been widely used. At present, the main raw materials of cement concrete blocks are cement and sand. Since the specific gravity of sand is relatively large, and the cement concrete blocks made of sand are relatively dense, the cement concrete blocks made of sand are relatively dense. The specific gravity is relatively large, and this cement concrete block has certain limitations in sound insulation, heat insulation, fire prevention and other properties. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a porous concrete block with light spec...
