COMPOSITION FOR HIGHLY HEAT-INSULATING HIGH-STRENGTH LIGHT-WEIGHT CONCRETE AND PRODUCTION OF HIGHLY HEAT-INSULATING HIGH-STRENGTH LIGHT-WEIGHT CONCRETE

摘要

PURPOSE:To provide a light-weight concrete having high heat-insulation and strength, exhibiting high fluidity in the production process and having excellent applicability and moldability. CONSTITUTION:The light-weight concrete of the present invention is produced by using cement, ultrafine siliceous powder, a high-performance AE water- reducing agent, a dispersion stabilizer and light-weight aggregate consisting of foamed inorganic particle as main compounding materials, compounding the above components at specific ratios, kneading with water and curing the kneaded mixture. The objective light-weight concrete having high heat-insulation and high strength can be produced by compounding the above specific materials at specific ratios.
