Abstract:
Cementless concrete based on high-calcium fly ash and slag sand from thermal power plants and excluding the use of ware aggregate has been developed by the Siberian State Academy for Mining and Metallurgy (SSAMM). The concrete has been patented. It consists of the following components: high-calcium fly ash - 30-40% slag sand with particle size 0 to 5 mm, 30-40% silica fume - 3-4% water (60-80oC ) - as needed, 16-37% Study and optimization of the properties of the created concrete led to a new approach to the problem, that is the methods of simulation modeling. The use of a computing technique in the investigation permitted attainment of more efficient data on the concrete composition and predict its properties.
