Test Of Thermal Insulation Glazed Hollow Bead Concrete And Analysis Of Building Anti-Seismic Performance & Energy Consumption

With the policies implementing of energy-saving construction and wall-reform in China, developing effective energy-saving construction materials have become one of emergencies in civil engineering field. As a high efficiency ecological building material with physical and mechanical properties of traditional concrete and better thermal-insulating ability, thermal insulation glazed hollow bead concrete was researched in Taiyuan University of Technology ( project of city construction scientific research list in taiyuan). In this paper, the compressive strength and thermal conductivity of thermal insulation glazed hollow bead concrete were studied and the anti-seismic performance and energy consumption of thermal insulation glazed hollow bead concrete building were analyzed on the basis of the simulation analysis of test data.Under the guidance of orthogonal experiment theory, the compressive strength and thermal conductivity of test block of thermal insulation glazed hollow bead reinforced concrete was determined and the data were also analyzed.Utilized the software of ANSYS, the anti-seismic performance of thermal insulation glazed hollow bead reinforced concrete was compared with that of reinforced concrete.Using the model of six-storey residential unit established by the software of DeST-h, the energy consumption of a single room, a single system and a entire building of thermal insulation glazed hollow bead ferroconcrete structure in air-conditioned quarter, heating quarter and a whole year was analyzed and compared with that of reinforced concrete structure.The conclusions drawn out from the analysis listed above are as follow:First, the thermal conductivity of thermal insulation glazed hollow bead concrete was decreased rapidly with the increase of the usage of glazed hollow bead. When the thermal conductivity of thermal insulation glazed hollow bead concrete closes to clay brick's, the compressive strength of thermal insulation glazed hollow bead concrete was higher than that of clay brick and the expectant effect was basically achieved. The applicability of thermal insulation glazed hollow bead concrete availability in engineering was also proved.Second, the principal and subordinate factors impacting compressive strength and thermal conductivity were gained. Meanwhile, the regression equation between the thermal conductivity and the usage of glazed hollow bead was drawn out.Third, the natural vibration period of thermal insulation glazed hollow bead concrete shear wall structure was larger than ordinary concrete shear wall structure. In the case of response spectrum, elastic interbedding displacement was very small; the shear is smaller than ordinary concrete shear wall structure. Thermal insulation glazed hollow bead concrete shear wall structure not only completely meet the requirements of anti-seismic criterion , but also better than ordinary concrete.Fourth, the energy consumption has a greatly fall in air-conditioned quarter, heating quarter and a whole year of thermal insulation glazed hollow bead reinforced concrete structures compared with that of reinforced concrete structures.As a new energy conservation building materials with good structural and thermal insulation performance, the feasibility of thermal insulation glazed hollow bead concrete was confirmed in this paper which was provided a valuable reference for a in-depth study and application in the future.At present, the thermal insulation glazed hollow bead concrete which was firstly study here over all the country was granted a national invention patent.( Patent No :ZL200610012726.2)...
