Design And Application Of High Strength Lightweight Aggregate Concrete In The Multistory Building Structures

With the rapid development of China’s economic construction，there are moreand more high-rise buildings and large span structure, which requires buildingmaterial toward the light, high strength and direction, which makes the high strengthlightweight aggregate reinforced concrete structural system is used more and morewidely. Structural systems of reinforced concrete, high strength lightweight aggregatecompared with common reinforced concrete structure, the structure bearing capacity,high stiffness, good seismic performance advantages, than the steel structure has theadvantages of good fireproof performance, local and overall stability of structure,steel saving. Now in China, more and more application of high strength lightweightaggregate reinforced concrete structure in high-rise structure, but the application ofhigh strength lightweight aggregate reinforced concrete structure is very limited. Highstrength lightweight aggregate concrete can combine the advantages of steel andlightweight aggregate concrete respective, overcomes the disadvantages of ordinaryconcrete self-important, lightweight aggregate concrete is brittle, provides a broadapplication prospect of high strength lightweight aggregate concrete.This paper introduced the general development of lightweight aggregate concrete,discusses the need to solve in the application of lightweight aggregate concrete in ourcountry, in order to guide practice. A comprehensive comparison of lightweightaggregate concrete and normal concrete, differences in composition on structure andperformance, and provide reference for the engineering application of the proper useof lightweight aggregate concrete. Based on the review of thirty years, China’s highstrength haydite and its concrete technology development, discusses the main reasonsaffecting the application and development of high strength Ceram site production, andthe key problems to be solved; on high performance lightweight aggregate andconcrete the possibility to develop in our country in detail, and the prospect of highperformance lightweight aggregate concrete development prospects in twenty-firstCentury.In this paper, the construction of a concrete calculation for a multilayerarchitecture of lightweight aggregate concrete, the mechanical properties meet theregulatory requirements under the premise of the same building, with two kinds ofmaterial’s mechanics performance analysis. Do some work as the concrete promotionCeram site reference, provides some basic data for the application of lightweightaggregate concrete, as the basis for the design units and the construction generalcontractor construction unit, when the decision.
