Research And Application Of Insulated And Adiabatic Wall Materials With Cement-based

The energy problem has become an important problem that influence the development of world economy, each country can solve this problem in the search for. In China’s energy consumption problem is more outstanding, and China’s building energy consumption accounts for the proportion of total energy consumption in the world, reaching25%. So to solve the energy problem of individual.This paper mainly studies the energy-saving insulation floor and the wall light. The performance I have been common plate increasingly unable to meet people’s requirements of thermal insulation material model, it is very necessary to. The main materials of retaining structure in reference with the building, it features mainly has good insulation properties, high compressive strength, low thermal conductivity, insulation resistance, and lower cost.Of this thesis is the study of the light sheet of cement-based insulation. In preliminary feasibility study analysis, the author designed three different sets of orthogonal test design, the three group of orthogonal test, get index data series, analysis and comparison of the data, select one of them for making the material of the wall plate scheme, a scheme for manufacturing wallboard material plan..In this paper, the first scheme is made of lightweight aggregate concrete EPS renewable materials, mainly used in the manufacture of wallboard. We benchmark test and benchmark test data analysis, the best fit obtained wallboard material ratio, but found the test block to produce dry density is high, which will cause the high thermal conductivity, it will affect the performance of thermal insulation materials. So the author try to plan a best reference group with incorporation of certain aluminum powder, aluminum powder can be produced and cement hydration substances after the chemical reaction, the gas will emit a certain amount, to " gas " role, will have a large number of the bubbles in concrete, this kind of dry apparent density will reduce, coefficient of thermal conductivity is reduced at the same time, increase the heat insulation performance.Second schemes for the preparation of the shale lightweight aggregate concrete, is mainly used for manufacturing floor. Through data collection and analysis, the optimal ratio of benchmark test. Because the concrete shall be used as floor material, its compressive strength of high requirements, and is the author trying to steel fiber doped with a certain amount of benchmark best group, through adding different amount of steel fiber, create block large, data collection of these specimens, the performance index parameters of the28d compressive strength, thermal conductivity, dry apparent density. Through the analysis of selected, select a set of optimal mixture ratio.This paper mainly is the study of lightweight thermal insulation sheet, we need the material has high strength, lightweight, thermal insulation performance. This involves the study of the apparent thermal conductivity, density, compressive strength. There are certain contradictions between them, both to each other, we must seek a balance, is to through continuous testing, the analysis of the data, finally get a relatively balanced optimum mix.
