Soil-cement of Normal Hardening on the Basis of the Argillaceous Raw Material and Copper Ore Processing of Waste in Eco-geology and Construction

Abstract

The paper examines properties, main characteristics and areas of application of soil-cement. The applicability of clay as a matrix basis of construction for a composite material is considered.The basis of soil-cement as a composite material is formed by such argillaceous materials as clay or sandy clay which activity depends on the dispersity of a medium, metal ion concentration, pH medium. Also, it is determined by the nature (genesis) of the clay rock, including the impurity content.The authors have developed and received soil-cement with the normal hardening the basis for which is formed due to the use of clay and copper slag. The use of soil-cement in the production of construction materials and structures enables one to guarantee the high technical and economic efficiency and environmental soundness of the technology which contributes to expansion of the raw material base in construction on the whole. The realization of such reserves of mineral raw materials is connected with a possibility of obtaining control over structure formation processes that can ensure sufficiently high physical and mechanical and strain-stress characteristics of soil-cement both for construction and reclamation of tailing dumps in eco-geology.
