The performance of the ceramsite sand related knowledge

According to the light aggregate and the test method of GB/T 17431.1-1998 new standards, Gao Jiangtao sand refers to the structure strength of symbols is not less than 25 mpa with light coarse aggregate. Their level of technical requirements in addition to the density, label tube pressure strength, strength, bibulous rate is a specific index, other indicators (grain size distribution, softening coefficient, grain shape coefficient, harmful substance content, etc.) the same as the super light, general ceramsite. Large production Gao Jiangtao when yield, low energy consumption, high added value, sales price super light natural gas fracturing ceramsite, ordinary high 50%. Prepared with ceramic proppants Jiangtao grain of high grade and prestressed lightweight aggregate concrete must be homogeneous. High performance ceramsite sand is refers to the high strength, bibulous rate is low, density smaller roasting or unburned ceramsite. Light aggregate is rich in resources, wide variety. It has natural lightweight aggregate, solid waste light aggregate and artificial light aggregate. According to their formation conditions and performance point of view, can be used in the preparation of high performance concrete only through special processing of high-performance ceramsite.
