The invention relates to the building materials industry and for the production of expanded clay.
Known raw material mixture for the production of expanded clay contains, mass%: clay raw materials 75,5-76,8; fibrous waste of initial processing of wool 0,9-1,4; water - the rest [1].
The objective of the invention is increasing the strength of expanded clay obtained from the raw mix.
The technical result is achieved by the fact that the raw material mixture for the production of expanded clay, clay-containing raw fibrous waste of initial processing of wool, water, as the clay raw materials contains clay of montmorillonite and advanced - sawdust, liquid potassium glass and lignin in the following ratio of components, mass%: clay of montmorillonite 73,0-77,0; fibrous waste of initial processing of wool 0,2-0,3; water 20,0-24,0; sawdust 0,2-0,3; liquid potassium glass, 1,0-1,5; lignin 1.0 to 1.5.
The table shows the composition of the raw material mixture for the production of expanded clay.
In the composition of the raw mix used clay of montmorillonite, including Al-montmorillonite and Fe-montmorillonite (nontronite). Use any sawdust, liquid potassium glass, with a density of 1.4-1.5 g/cm 3 and silicate module 3,6-4.
Components are batched in the required amount and mix. From the received raw material mixture is formed into pellets (fraction 20-40 mm), which are dried and fired at a temperature of 1100-1150°N
