According to the strength of ceramisite is divided into high strength ceramsite and general ceramic.

(1) high strength ceramsite

According to the (lightweight aggregates and its test methods) GB/T 17431.1 - 1998 new standards, high strength ceramsite refers to the use of lightweight aggregate strength grade of not less than 25MPa structure. The technical requirements in addition to density level, the cylinder pressure strength, strength, water absorption rate of specific indicators, other indicators (particle size distribution, softening coefficient, grain shape coefficient, the content of harmful substances etc.) and ultra light, the same general ceramsite. Production of high strength haydite, yield is low, the energy consumption is larger, high added value, sales price than ordinary super lightweight aggregate haydite, high about 50%. High grade and prestressed lightweight aggregate concrete prepared with high strength ceramsite must be homogeneous.

(2) the ordinary ceramic

According to the "GB/T lightweight aggregate and its test method" 17431.1 - 1998 new standards, ordinary ceramic refers to strength less than 25MPa structural lightweight aggregate. General ceramic wide application, large market potential.
