IMPROVING THE EFFICIENCY OF MANUFACTURING FINE-GRAINED CONCRETE THROUGH THE USE OF MAN-MADE SANDS AND COMPOSITE BINDERS

Abstract

In this paper, an attempt has been made to substantiate the need for utilization of man-made sands and sands of mechanical origin obtained from local rocks as a result of mining, processing into crushed stone and sawn materials. The use of waste products contributes to the expansion of the raw materials base of the construction industry, increase in the number of composite binders when used as a filler, large-scale propagation of fine-grained concrete for various products along with minimization of material and energy costs, expanding the practice of using stone-crushing, stone-sawing products and managing new technologies for environmental conservation. The decision to utilize man-made waste materials (sands) of mechanical origin is particularly important for large-scale expansion of the production of fine-grained concrete for a region where no metal (reinforcement steel) is manufactured.
