17. Freeze-thaw: the loss rate of compressive strength is not more than 25%, and the loss rate of dry weight is not more than 2%. The technical indexes of corrosion resistance and high temperature resistance are better than those of clay sintered brick.
Extended data:
Baking-free brick:
Use fly ash, coal cinder, coal gangue, tailings, chemical slag or natural sand, sea mud, etc. (One or more of the above raw materials) is the main raw material, and a new wall material is called baking-free brick without high temperature calcination.
This product conforms to China's general policy of "protecting cultivated land, saving energy, adapting to local conditions and using local materials" and the State Council's opinion of "strictly limiting the destruction of farmland and burning bricks and actively promoting wall renovation".
It conforms to the provisions of the Notice of the Ministry of Finance of State Taxation Administration of The People's Republic of China, People's Republic of China (PRC) and People's Republic of China (PRC) on Continuing to Implement the Preferential Policies of Value-added Tax for Some Resources Comprehensive Utilization Products (Caishuizi (1996) No.20), and this product is a building material product exempted from value-added tax.
Features:
The characteristics of baking-free brick are not found in any other wall brick. Through reasonable scientific formula, a certain proportion of coagulant and trace chemical additives, and reasonable equipment and technology to strengthen particle size, humidity and mixing degree, the best plasticity can be achieved.
After high pressure pressing, the brick body hardens rapidly. The longer the time, the better the effect, the better the practicability of the brick, and the appearance of the wall is neat and not soaked.
Because of its high strength, good durability, standard size, complete appearance, uniform color and simple and natural appearance, this material can be used as drywall or any external decoration.
Therefore, it is a promising substitute for clay bricks. Waste utilization, soil saving, energy saving, wide source of raw materials, environmental protection, high strength, water resistance, weather resistance, corrosion resistance and freeze-thaw resistance.
Development prospect:
The development, popularization and utilization of baking-free bricks will have a good development prospect in China.
According to the national data, in terms of raw materials, China's solid waste storage and annual emissions are very huge, and this kind of waste is stored in artificial warehouses by natural accumulation.
These wastes not only occupy a lot of land and pollute the surrounding environment, but also need to invest a lot of unrecoverable waste disposal funds every year, which has become a heavy burden for enterprises.
At present, there are thousands of large and medium-sized coal production enterprises and thermal power generation enterprises in China, and hundreds of millions of industrial wastes such as fly ash, slag, slag, tailings and coal gangue need to be discharged and treated every year. Enterprises spend a lot of money to digest or transform industrial waste.
It can be seen that the production of baking-free bricks from industrial waste residue has become a cause of saving land, soil and waste, environmental protection and energy saving, and benefiting future generations.
Develop new wall materials with industrial waste residue and other non-clay as the main raw materials, and actively promote energy-saving buildings.
It is an effective way to effectively protect cultivated land resources, improve building functions and living comfort, and promote the structural adjustment of wall materials, industrial optimization and upgrading and technological progress in the construction industry. Wall materials are indispensable and important building materials in the construction industry.
The construction industry is the pillar industry of the national economy, and it plays an irreplaceable role in the process of China's modernization. Its huge building market capacity also provides a very broad prospect for the production of wall materials.
On June 30, 2003, the production and use of solid clay bricks were banned in cities with per capita arable land 170 mu.
With the strengthening of "forbidden real estate", traditional brick and tile factories have closed down and stopped production, so we have to rationally use and develop renewable resources and develop new wall materials.
Make full use of fly ash, coal gangue, slag, stone powder, tailings, construction waste and other waste residues and wastes, save land resources, protect the environment and solve pollution problems.
The baking-free brick market has won unprecedented market opportunities.
