Description

The invention relates to the production of building materials and can be used in the manufacture of expanded clay from weakly argillaceous clay raw materials.

The purpose of the invention is to reduce the total density of claydite.

The raw mix for the production of expanded clay includes 98.5-99.3 wt.% Q weakly clayey raw material and 0.7-1.5 wt.% Waste rubber rubber products as an organic mineral additive.

Waste from the production of rubber products is a powder of a fraction of 0-2 mm, which is formed during machining, for example during grinding, of automobile tires — jHoro transport. The powder contains 2o rubber up to 50% and various mineral and organic components - masPrimer. Waste rubber rubber production waste in the amount of 0.7-1.5 wt.% In the form of a powder with a fraction of 0-1 mm was injected into the clay weakly lumping raw materials of the Mironovsky field. The mixture was sewed until a homogeneous mass was obtained, from which the granules were formed using a plastic method. The granules were dried at 100-105 ° C. L were annealed using the conventional claydite technology.

Specific examples of the composition of the raw material mixture and the properties of expanded clay are presented in the table in comparison with the known composition using one type of weakly fracturing clay from the Myronovsk field.
