The Burning-Free Brick  is a brick-making machine that replaces loss with cement carbon residue coal ash without relying on charcoal kiln burning. It can save production space, save labor, and replace the energy of coal combustion with electricity.The advantages are as follows：

1.Protect cultivated land and avoid destroying fields

Replacing the clay solid brick with the waste slag bricks which can reduce the combustion bricks and destroy the soil.

2.Save energy and reduce energy consumption

The（Burning-free brick）waste slag brick  saves energy in two aspects.

① to save coal consumption of burning bricks.

② to save building heating and cooling energy consumption.

(1) Reduce CO2 emissions and protect the environment

The firing of solid clay bricks and brick kiln should discharge a large amount of CO2, which makes air quality worse and aggravates the greenhouse effect.

Therefore, from the perspective of protecting the environment, solid clay brick will be phased out in the development of waste brick（Burning-free brick）

(2) Many functions and good performance

Compared with solid clay bricks, the waste slag hollow blocks have the advantages of heat preservation, sound insulation, fire prevention, light weight, shock resistance, firmness and beauty.

The houses constructed by them have strong earthquake resistance and comfortable living, which is conducive to lightening the building. 

(3) Reducing construction cost, significant economic advantages

The construction of houses using waste slag blocks（burning-free bricks）can save engineering cost by 25%, shorten construction time by 50%, save wood by 70%, save steel by 40%, save masonry mortar by 50%, save plastering mortar by 40%, and save labor by 40%. Heating energy consumption is reduced by 30% to 50%. At the same time, the block building abolished the traditional manual tile work during construction, reduced most of the formwork and high-level scaffolding, and exempted more than a dozen construction procedures, greatly reduced the labor intensity and improved the safety and scientificity of the construction work. Therefore, the waste slag hollow block has good economic and social benefits.

(4) Saving brick burning energy

Traditional clay bricks produce a large amount of coal, and each 10,000 bricks consumes 1.3 tons of standard coal. The annual consumption of standard bricks is 60 million tons, accounting for about 5% of the country’s total coal output.

(5) Saving heating and cooling energy consumption

The annual heating energy consumption in northern China is about 120 million tons of standard coal. In the south and other dry and hot regions, the energy consumption for cooling in summer is about three times that of heating. If this energy consumption is converted into coal of about 300-400 million tons of standard coal. . This number is very amazing, and the construction of houses with waste slag hollow blocks, especially the construction of houses with energy-saving thermal insulation hollow blocks, can achieve a warm winter and cool summer. If all the houses in the country are now insulated and insulated, the annual energy saving will be equivalent to 500 million tons of standard coal, and the per capita energy saving is 0.35 tons of standard coal. The energy saving effect is very impressive.
