CALCULATION, DESIGN AND IMPLEMENTATION OF MULTI-LAYER HEAT-RESISTANT REINFORCED CONCRETE STRUCTURE

Abstract

The article presents the experimental results of determining its strength under normal conditions as well as the residual strength under the influence of high 8000С temperature on the new composition of heat-resistant concrete based on local industrial waste. Practical application of heat-resistant reinforced concrete slab designed for heat storage in brick cooking stoves. A new heat-resistant reinforced concrete slab made on the basis of industrial waste is intended for covering the walls and tops of trenched brick kilns. Analytical data on the scientific research carried out over the years, conclusions on the relevance and necessity of the problem, experimental test results, new research results on the porosity and structure of the material of the heat-resistant plate construction are presented and analyzed. The proposed heat-resistant reinforced concrete slab reduces the heat dissipation in brick kilns to the environment, and this provides an opportunity to reduce the energy consumption per product unit, increase the efficiency of the kilns, and lower the cost of the product. In addition, it allows to increase the temperature in the brick baking ovens to 1100-1200 0С, speeds up the brick baking process, and increases the quality of the product. The plate makes it possible to mechanize the opening and closing of the stoves, and to use them many times. This heat-resistant reinforced concrete slab has been tested in brick factories in Namangan and Andijan regions, and the obtained scientific results are of practical importance
