Research And Analysis Of Mechanical Properties & Thermal Properties Of Thermal Insulation Glazed Hollow Bead And Ceramisite Bearing Concrete

Nowdays, the whole world energy crisis specific gravity taken up gradually, the proportion of building energy conservation in the energy conservation is more and more big. Therefore ,The system, developing a kind of new building structure which is seismic resistance , economy , energy-saving residential cost becomes important civil engineering field problem. This paper takes it as target ,researches and analyses on thermal properties of thermal insulation glazed hollow bead and ceramisite concrete.Currently used in the construction market of heat preservation material into organic and inorganic kind. Organic mainly contains polystyrene (EPS), extruded board (XPS), powder polystyrene particles, polyurethane, organic materials, Inorganic kind mainly inorganic insulation mortar. Traditional insulation engineering method is after main body structure formed, then heat preservation material paste or blots out the construction. The traditional insulation system, not only the construction speed is slow, cost is high, but also building structure is not safe. In addition, organic heat preservation material still has many shortcomings, such as the inevitable fire hidden large, the high cost, easy to the drum, such as durability. Based on the above reasons, this article from the mixing ratio, and the basic mechanical, thermal performance in the test and research work of thermal insulation glazed hollow bead and ceramisite bearing concrete, combined with a specific project of thermal insulation glazed hollow bead and ceramisite bearing concrete structure seismic and thermal performance theory simulation analysis. These research works are as follows:(1) Do analysis and experiment of raw materials of thermal insulation glazed hollow bead and ceramisite bearing concrete, from its production development and modification of two kinds of raw materials for the follow-up work, optimize laid a foundation.(2) Using orthogonal test method and testing compressive strength and thermal conductivity of 18 different proportion of specimens of thermal insulation glazed hollow bead and ceramisite bearing concrete The dosage of various factors of compressive strength and thermal conductivity of thermal insulation glazed hollow bead and ceramisite bearing concrete are arrayed, and secondary factors, for follow-up tests.(3)Based on the orthogonal experiment, choose the optimal portfolio selection, mix the plan for further test, the test different beads of ceramic and glass dosage, strength grade for 32.5,42.5,52.5 Portland cement, this joint strength grade for Portland cement fly ash ceramisite is mixed, iron ore and rock, mixing degree turpentine, mixed typeⅠcement-tailings admixture, etc, successfully drawed thermal insulation glazed hollow bead and ceramisite bearing concrete,which is C10 ~ C50 strength, thermal conductivity it secondly introduces 0.120~0.650 W / (m·K). So thermal insulation glazed hollow bead and ceramisite bearing concrete is feasible, and the other component material combination of concrete construction, and has good maneuverability.(4) Take ANSYS software, with a large office of Taiyuan,which was established of thermal insulation glazed hollow bead and ceramisite bearing concrete frame structure system, through the modal analysis and spectrum analysis and comparison, the system and ordinary concrete frame structure vibration periods, basal shear, elastic deformation, stress and displacement Angle, shows that the system can not only satisfy the standard aseismatic design requirements, and has better than ordinary concrete frame structure of the seismic performance.(5) Through thermal performance analysis and calculation of thermal insulation glazed hollow bead and ceramisite bearing concrete system, the system that energy can meet our cold area energy-saving building 65% of objectives.Through the experiments and analysis, thermal insulation glazed hollow bead and ceramisite bearing concrete is a kind of common concrete both physical and mechanical properties, thermal insulation performance and the green, environmental protection, high ecological building materials. Using glass hollow beads and ceramsite, the concrete possesses good heat insulation system integrity, good performance, and can form a comprehensive since the insulation system.This study thermal insulation glazed hollow bead and ceramisite bearing concrete " has been the state intellectual property office invention patent license (ZL200610012726.2), and subsequent research has higher intensity, low thermal conductivity of thermal insulation glazed hollow bead and ceramisite bearing concrete has been declared by the state intellectual property office invention patent filing number (200910075208), Currently the out of C40 compressive strength, thermal conductivity of 0.2 W / (m·k), thermal insulation glazed hollow bead and ceramisite bearing concrete has passed inspection center and issue an inspection report, This subject as a series of research glass hollow bead insulation mortar application research, which is an important part of Shanxi Province, the research achievements of the national famous experts identified by the organization has reached the international advanced level, and science and technology second progress prize in Shanxi Province.
