EXPERIMENTAL STUDY ON HIGH-PERFORMANCE SHALE CERAMSITE CONCRETE BASED ON INSULATION STRUCTURE

In order to make up high performance ceramsite concrete ( HPCC) and be applied in engineering practice， the best mixture ratio of high-strength shale ceramsite concrete ( HSSCC) no less than LC40 is obtained by orthogonal tests based on the indexes of strength and thermal conductivity，then the effects of sand and different fibers on physical-mechanical properties of CC are studied． The test results show that the sand has little effect on strength，but steel fibers have a great deal when added 2%，the compressive strength，splitting strength and flexural strength are all higher than ordinary one． Besides，the axial strength is similar to cube compressive strength，and the elastic modulus is lower，the peak strains and the total strains are larger． In the end，the integration system of insulation building is founded and the economy energy rate is not less than 65% by aseismic check based on the upper test results，including of the physical-mechanical properties，and the supposed several types of structure concretes and outer protective structures．
