Clays of The Kasminsky Manifestation in The Kemerovo Region — Promising Raw Materials for Production Clinker Bricks

Provide data on the use of clinker bricks in modern construction are given. Based on the analysis of the decree, it is believed that only clay raw materials of low-temperature sintering can become a reliable raw material base for increasing the production of clinker bricks, capable of producing shingles with a water absorption of less than 2% without signs of burning in the temperature range of at least 50^о. It is emphasized that the most acute problem is the increase in the production of clinker bricks in the east of the country, one of the reasons for which is the lack of reliable base raw materials. The results of the studies of the revealed Kasminsky manifestation of clays with predicted reserves of at least 5 million m³, which belong to the strongly sintering clay raw materials of low-temperature speckle with a beige and brown-reddish skull, are presented. Provide is a hacteristic chemical and mineral composition, which is characterized mainly as hydro-trace with an admixture of quartz. It is shown that durability of the burned samples already at a temperature of roasting of 1000^оС wasps is sufficient for a brick – strength at compression of 70–75 MPa and at a bend about 20 MPa. At a temperature of roasting of 1100^оС wasps – strength at compression is 90–125 MPa and at a bend of 28–35 MPa. The water absorption less than 2.5% necessary for a road brick is reached at temperatures of roasting of 1030–1040^оС wasps. Based on the results of the work carried out, taking into account the pre-burning and burning properties of clays, the location of the manifestation, mining conditions and reserves, the clay of the Kasminsky manifestation is very promising for the production of wall and road clinker bricks in Siberia.
