Q:Shale brick and clay brick? Answer before you know it

Has the advantages of high strength, thermal insulation, heat insulation, sound insulation and other characteristics, in order to shale as the main building materials brick construction, is the biggest advantage of shale brick and clay brick traditional construction method is exactly the same, without any additional special ` construction facilities, special tools, is the best substitute for traditional clay solid brick.

Q:What are needed to make refractory bricks with micro silica?

Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
