Research On The Crack Control Technology For Concrete Perforated Brick And Small Hollow Block Wall

The current with the rapid development of China’s economy and the accelerating of urbanization process, there is an increasing demand for all kinds of resources; This worldwide problem and insufficient resources, also restricts the development of our country. Therefore has to be the new wall materials to replace the traditional clay brick wall materials reform, to protect non-renewable resources (such as land resources, coal resources), to purify the environment. But the new wall materials in the process of replacing traditional wall materials, due to problems such as leakage, cracking, heat preservation, affected its promotion; Especially the wall crack is the most representative.Aiming at this problem, this paper analyzes the new wall materials (concrete porous brick, small block, etc.) in the domestic research status and achievements of research the development of new wall materials at home and abroad and its application, especially in maanshan city has built new wall materials and construction engineering market research, manufacturers and the production, construction and application of new wall materials, and so on and so forth of on-site inspection and tracking, the cracking of thought, is not only the new wall materials itself, but rather a and wall materials, design, construction and management aspects of the relevant system. In order to promote the new wall materials, to prevent wall cracks is extremely important. Aiming at the new wall materials (concrete porous brick, small block, etc.) wall crack technology a great deal of investigation, analysis, experiment, research. First of all, according to a new wall materials (concrete porous brick, small block, etc.) in the process of production and use of cracks, sums up the causes of cracks. Then based on the block, the researches on the mechanism of the temperature and shrinkage summarizes block wall temperature stress and shrinkage stress of load value, through the finite element method, simulate the cracking process and the position of the wall, the wall body crack technology analysis and research. Finally created small hollow concrete porous brick, block, provides the technical guidance, for small hollow concrete porous brick, block, etc. The cracks of new wall materials have good control effect, is of great significance for the promotion of new wall materials.
