摘要

在本研究工作中,研究了利用玻璃废料生产混凝土的可能性,同时保持其质量。在过去几年中,用于生产建筑材料的天然原材料短缺的问题并没有失去其相关性。这是由于快速发展的建设步伐。在这方面,建筑业的任务是将企业重新定位为技术原材料的消费。从结构和理化性质上看,鱼片是一种人为来源的矿产资源。在塑性混凝土混合料中分别加入0 ~ 20mm粒径的碎玻璃细片,分别为细分散质量的0、30、50、70、100%,用此量的碎玻璃细片代替砂子。将不同配比的混凝土混合料制成的混凝土试样在正常硬化条件下保存7天和28天,然后进行混凝土强度和其他特性的测试。为了提高混凝土样品的强度,在后续的系列样品中使用破碎的花岗岩砂和碎石作为集料。所进行的研究使我们确认,用精细分散的玻璃代替部分沙子是一种可接受的方法,可以减少天然原材料的使用,同时保持混凝土混合物的强度特性。关键词:混凝土,细碎,研磨,细分散,砂,强度,水泥,复合材料,工艺原料。

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. Keywords: concrete, cullet, grinding, fine dispersion, sand, strength, cement, composite materials, technogenic raw materials.
