Paving Clinker of Low-Temperature Sintering on the Basis of Opokamorphic Rocks

Abstract:

The article presents the results of work on manufacturing paving clinker based on carbonate-argillaceous opokas belonging to the group of siliceous opal-cristobalite rocks. General characteristics of these rocks are given. Their composition, properties and spread patterns are shown. It has been shown that the introduction of strong minerals up to 1% allows creating products with water absorption of less than 2.5% at burning temperatures of 1050-1100 ° C. The resulting products are yellow and fully meet the requirements of regulatory documents. The main technological factors in the production of paving clinker are as follows: the grain composition of the crushed raw materials, burning temperature of the products and the amount of mineralizer. The production of paving clinker based on carbonate-argillaceous opokas can be organized either by extrusion molding or by compression molding.
