Mineral binding material with the use of paper manufacturing wastes

Abstract

The possibility of making of mineral astringent material of the low temperature burning at utilization of wastes of production of paper – scope is shown. The analysis of compositions of raw material mixtures on the basis of the system chalk -clay-scope is conducted with varying of concentration of scope at the set descriptions of product of burning. The compositions of mixtures with introduction of 25 - 51 % scope is determinated. The features of phase composition and indexes of properties for mineral astringent with the use of scope as technogenic raw material are shown at the maximal temperature 1100 0С of burning.
 Industrial use of multi-tonnage waste of various industries, including scopes from paper production, allows to solve complex issues of technology of production of silicate materials, resource conservation and ecology.
 The feasibility of using scopes as man-made raw materials in the technology of mineral binders is determined by the peculiarities of the chemical and mineralogical composition - the presence of a complete complex of oxides necessary for the formation of a given phase composition during firing and the possibility of intensification of the sintering increase in the reactivity of the silicate system at.
 The efficiency of practical use of an osprey on the basis of the above developments is defined as the prospect of increasing the volume of utilization of industrial waste, as well as obtaining a new kind of mineral binder material in the low-temperature firing, which differs from romance with improved strength indicators.

Application of varieties of technogenic raw materials in cement technology

“…Scope is formed during the production of paper and cardboard and is a mixture of cellulose fibers, organic dispersed and inorganic substances. Features of the composition and a certain heat-generating ability of the scope determined the directions of well-known research and development on its utilization in the energy and agro-industrial complexes for the manufacture of building materials [14][15][16]. At the same time, in relation to building materials, it is proposed to use the scope as filler in the manufacture of heat and sound insulating plates and as a raw material component for the manufacture of expanded clay and agloporite -expanded granular ceramic materials.…”
