Description

A kind of environmental bamboo charcoal vitrified brick

Technical field

The present invention relates to vitrified brick technical field, particularly relate to a kind of environmental bamboo charcoal vitrified brick.

Background technology

All with clay, shale, coal gangue or flyash for raw material, obtainedly through shaping and high-temperature roasting be referred to as vitrified brick for the brick of building load-bearing and non-bearing wall body by laying bricks or stones.

The production of common brick and use, in existing more than the 3000 year history of China.Now, in the materials for wall used in construction project, common brick is still occupied an leading position.Although there is many deficiencies in common brick, but due to cheap, technique is simple, design and construction technique is ripe and the reason such as the use inertia of people, common brick, within considerable time from now on, particularly in rural area, remains one of main materials for wall.

In construction industry, materials for wall is the important composition part of construction industry, and the consumption of materials for wall in building materials is maximum.In recent years, along with the propelled at high velocity of urban construction, the every Year's consumption of China's wall body brick, more than 6,000 hundred million pieces, consumes about 660,000 mu, soil, consumes mark 9,000 ten thousand tons, coal.Under the dual function of environmental requirement and Policy Conditions, solid clay brick is withdrawn from the market just gradually, promotes novel wall material, reduces and stores up occupation of land, superseded clay brick production capacity, Economization on land is the trend of the times of environmental requirement, and the environmental protection innovation of materials for wall industry is imperative.

Opal is the silicon-dioxide gelling body of natural sclerosis, containing the moisture of 5-10%.Opal is different from most jewel, belongs to amorphousness, due to the water loss in jewel, becomes dry gradually and occurs crack.Opal belongs to opal class in mineralogy, is the jewel with chatoyance effect, is a kind of moisture amorphous silicon-dioxide.Alkaline residue refers to the waste residue discharged in ammonium alkaline process alkali producing process.It is the waste residue of main ingredient that alkaline residue composition mainly comprises the calcium salts such as calcium carbonate, calcium sulfate, calcium chloride, also containing compositions such as a small amount of sulfurous gas.
