Zusammenfassung:Lightweight concrete comprises following components: river sand 20-50% light stone 25-40% cement 15-25% additives 0-7% Light dry concrete according to the invention is 30% lighter than conventional concrete and has developed early strength. Hardening capacity is achieved after 8 hours of completion of construction. It also has high end strength (>40MPA), so the resistance to compressive and bending forces is higher than conventional lightweight concrete. In addition, it has waterproofing capacity, heat and sound insulation. Light dry concrete according to the invention can be lighter, so it can carry more and reduce transportation costs, reduce foundation costs, energy costs for cooling or heating construction.
