The Investigation And Development Strategy Reseach Of Deyang's Wall Material

Wall has function of load-bearing, surrounding and separating in building construction.This paper has paid attention to the research of the wall material, which is one of the important parts in the building material industry of our country. The usage of it is around 1/2 of the all building material usage, the value of it is about 30% of the total building cost, and the total value of it is near 1 /3 of the total value of the building material industry. The thermal properties of wall materials can influence the consumable energy of building directly, which is about 25% of the total building consumable energy and is near 1/2 of the total consumable energy of building material industry, Therefore,the properties, quality and economic efficacy of building project can be influenced by the properties and price of wall materials transparently and heavily.As the diversity of wall material, there is no present research on wall material in Deyang City. Also, in order to reduce the disparity between Deyang and other developed zones, it is necessary to investigate and know the situation of production and application of wall material. of quality examination from some authoritative quality examination organizations, we conclude that the basic situation of Deyang City's wall material manufacturers are as follows: productive technology equipments are in a relatively backward state,constitution of products needs to be improved, products are not good for building saving energy,the sustainable development capacity is relatively week, most of wall material products in Deyang City are still solid bricks made by sinter shale.Wall material is an important part of building material industry in our country. Building wall material industy is typically resource wasting, power wasting and labor intensive. Recently, in the actual background of population expansion, resource scarcity and environment deterioration, the development and evaluation research of province and city all over the country are increasingly concerned, in order to respond national policies such as national wall material reform and building energy conservation and to drive our wall material industry to develop in the pattern of sustainable development.Questionnaire on development of wall material associated with relevant national policies is designed to analyze the newest information on production and application of wall material in Deyang, and the research methods include interview on the spot and consulting some works and relevant construction branches. Based on the investigation into the present status, and according to the fact of the nature resource and waste residue emission in Deyang, wall material inside and outside is reasonable chosen. Using the national estimation system of wall material, an impersonal evaluation is made on index of quality and environment by experts invited. And wall material types suitable for long-term development are analyzed according to the characteristic of Deyang.Based on some issues discovered during investigation and estimate results, contacting with the fact of the nature resource in Deyang, corresponding development countermeasures of wall material in Deyang are put forward. It can provide references for government to establish material development policy. And it is helpful for production and application of wall material in Deyang.
