Waste sand trails brick technical issues to be addressed in the past, a lot of people tried to use the waste sand system trails brick. However, due to the low strength of the system to fail. First, the main cause of this problem of waste sand degrees smaller, more cement binder, waste sand in the dust on the strength of cement. In order to solve these problems, we carried out a large number of experimental studies, have carried out more than 100 formulations over 10 kinds of materials forming test, adjust the particle size and the amount of each component, adding special additives, and through a strict variety of testing and data analysis, preferably out of the ideal formula would effectively guarantee the mechanical properties of the brick, the brick to reach the GB pavers of the mechanical index.

The trail brick manufacturing and applications take full advantage of the foundry sand forming the advantages of using homemade equipment has developed a variety of products with fine surface structure and complex shapes. A plant and laying of channel and part of the road, through this process, not only can the use of waste sand and water residue can also use the cupola, to clean up the oxide scale and other waste materials by the use of proven materials for improving the strength of the bricks and The wear resistance has a very good role. The success of this process, which can handle more than 80% of the casting of solid waste.

Waste coke briquette instead of the end part of the coke waste coke powder coke crushing the powder. Foundry coke to join the cupola should be screened out. I Foundry and Casting Plant in each of the production process, can produce thousands of tons of waste coke powder, about 5% of the total coke consumption. Molding technology, these materials are per tonne more than 100 yuan low as the low-level fuel. Coke is the main raw material of the casting production, coke supply in recent years there have been ten years without a comprehensive tensions and spiraling prices, and sometimes the price is more than 2,000 yuan / t. If these materials re-use, and can bring hundreds million worth of economic benefits. Therefore, as soon as possible the development of coke powder molding technology to produce high strength, heat burning, low cost type coke is an urgent need to reduce casting cost.

Thus ability sulfate and acidic media, corrosion penetration, the life expectancy of up to over a thousand years, so this material can be used in corrosive media environment. The role of high temperature: the CBC composite material is based on the ionic bond and covalent connection-b ased, unlike cement-based materials are very sensitive to heat and high temperature hydrogen bond connection, so the fire antiknock ability. Excellent water resistance: the CBC composite internal structure dense, porosity, and external chemicals to water as the carrier is difficult to penetrate inside the material, and therefore very prominent impermeability can be used as a hydraulic material steel casting foundry
