Artificial Broken Stone Production for Industrial and Civil Engineering: Technological Parameters

The paper presents the results of investigation according to which the optimal fraction composition of clay concrete from Taskala gaize is found out. Its physical and mechanical properties are taken into account. The optimal fraction for crushed clay concrete is as follows: 5-10 mm, 10-20 mm and 20-40 mm. The paper describes the influence of various technological factors on physical and mechanical properties of artificial crushed rock made from gaize. The role of preliminary thermal treatment of clay concrete particles and fractions is also looked into. According the results of the investigation the optimum thermal treatment temperature is stated. It's 200-3000°С for chert gaize and 400-4500°С for clay materials.
