Use of glauconitic sand as a filler in the concrete mixes production

Abstract

In recent years, any production tries to minimize labor costs by automating processes. Because of the high rate of automation, machines have come to replace people. In addition to reducing the share of human labor and increasing machine labor, any manufacturer seeks to reduce the cost of raw materials, which contributes to the search for new solutions in the use of old materials. Russia’s natural resource base is quite diverse, with special attention paid to the processing of technogenic waste and the creation of resource-saving technologies. Waste generation occurs at all stages of the movement of raw materials: from the moment of its extraction, when it is still a natural resource, to the end of operation of the product made from it. Waste dumps are a rich source of raw materials for the construction materials industry, as many of them are close to natural raw materials in their composition and properties. The complex physical and chemical composition and structure of waste from a number of industrial productions allow considering them as a real raw material base for the construction materials industry. The paper describes the principles of selecting the composition of concrete on glauconitic sand. Glauconitic sand is a waste product, which is why its use reduces the cost of concrete mixes and products made from them.
