Composite Concrete Paving Stones for Road Construction

Abstract

The society pays attention to the reduction of construction costs and modern technologies and recommends using environmentally friendly and durable road paving materials instead of traditionally used asphalt concrete. Many years of experience accumulated in European countries shows the effectiveness of laying streets with small paving stones. Currently, the paving stones are made of natural stone (paving stones), ceramic stone (clinker) and fine-grained concrete. The most durable paving blocks are paving blocks, but for their production it is necessary to dig quarries and process precious stone, resulting in small waste. One of the main factors hindering their use in the production of ceramic materials is the high sintering temperature (1500°C), which significantly increases energy consumption. Concrete screed is mainly made of fine-grained concrete, but the screed itself is not as strong as blocks and clinker. In this paper, a review of studies on the inclusion of glass in the composite composition of concrete floors is carried out. Discussed of how the physical and mechanical parameters of concrete are subject to changes
