MINERAL BINDER BASED ON MAN-MADE RAW MATERIALS

Abstract

The possibility of manufacturing mineral binding material on the basis of multi-tonnage waste from other industries was investigated. The combination of modern physico-chemical methods of analysis of silicate materials with standardized tests of cement properties are used. With the use of the computer program "Clinker", calculations and analysis of the possible ratio of components in the system of chalk - rice husk - paper pulp (scope) were carried out. New compositions of raw material mixtures with a content of 64 - 71 wt.% of the specified waste were determined. The possibility of adjusting the indicators of binding properties - the terms of hardening when varying the quantitative ratio of rice husk: scope in the composition of raw mixtures from 2: 5 to 4: 2.5 was noted. The peculiarities of the formation of the phase composition during firing with a maximum temperature of 1400 ºС and the properties of the mineral binder when varying the quantitative ratio of the components in the composition of the initial mixture are shown. It was concluded that the use of large-tonnage industrial waste - rice husk and paper scope as man-made raw materials is promising in the mass production of mineral binding materials.
