RESEARCH OF THE PROCESS OF CONCRETE PRODUCTION USING CULLET
In this research work, was studied the possibility of using glass waste to produce concrete, while maintaining its quality.The problem of the shortage of natural raw materials for the production of materials for construction purposes has not lost its relevance over the past years.
This is due to the rapidly developing pace of construction. In this regard, the task of the
construction industry is to reorient enterprises towards the consumption of technogenic raw materials. In terms of structure and physicochemical properties, cullet is a mineral resource of anthropogenic origin. Cullet of crushed glass with a grain size of 0-20 mm was introduced into the plastic concrete mixture in the amount of 0, 30, 50, 70 and 100% of the mass of finely dispersed, replacing the sand with this amount of cullet. Concrete samples made from concrete mixtures of various compositions were kept for 7 and 28 days under normal hardening conditions, then a test was carried out to determine the strength and other characteristics of concrete. In order to increase the strength of concrete samples, crushed granite sand and cullet were used as aggregates for subsequent series of samples. The conducted research allows us to confirm that replacing part of the sand with finely dispersed glass is an acceptable way to reduce the use of natural raw materials while maintaining the strength properties of the concrete mixture.
