Structural structural materials by high strength-lightweight concrete and its manufacturing method

摘要

In the present invention, although the concrete most commonly used as a construction material has excellent performance and economical efficiency, since the strength is lower than the unit weight, the cross section of the member is enlarged to increase the self weight of the structure and reduce the use area. Lightweight concrete having an optimum mixing ratio of 270, 350 and 450 kg / cm 2 for the production of structural high strength lightweight concrete having a unit weight of 2.0 ton / m 3 or less.;It is possible to manufacture the concrete mixer of high strength and lightweight concrete, and it can be manufactured by existing concrete mixer production plant. By applying it to the actual site structure, it is possible to secure the technical force of high strength-lightweight concrete construction and to reduce the weight, sound insulation, Reduction of construction cost, use of artificial lightweight aggregate to cope with depletion of natural resources and contributing to nature conservation, as well as commercialization of high-quality, high-strength, lightweight concrete that can secure international competitiveness through opening the construction market.
