Embodiment Construction
[0013] Weigh raw materials according to the following proportions
[0014] The block skeleton is made of:
[0015] Cement 40%, Fly Ash 40%, Gypsum 10%, Perlite 5%
[0016] Sawdust 5%
[0017] Ultra-light foamed concrete is made of:
[0018] Cement 40%, Fly Ash 40%, Gypsum 15%, Chemical Foaming Agent 5%
[0019] The preparation method of the present invention is:
[0020] Firstly, each raw material is weighed according to the weight ratio for subsequent use.
[0021] Secondly, mix cement, fly ash and gypsum with a special foaming high-speed mixer for 1-2 minutes, add 5% chemical foaming agent and stir for 1 minute, pour into a special template for foaming, and the foaming will be completed after three hours. Made of ultra-light foamed concrete insulation layer.
[0022] Thirdly, to make self-insulating blocks, add cement, fly ash, gypsum, perlite, sawdust, and add water to stir for 2 to 3 minutes, then carry out mortar covering, composite glass fiber cloth, rolling, layin...

Abstract
The invention relates to a self heat-insulating external wall block which comprises a block framework and an ultralight foamed concrete insulating layer, wherein the block framework is made from cement, fly ash, gypsum, perlite and sawdust, and the ultralight foamed concrete is made from cement, fly ash, gypsum and chemical foaming agents. The compressive strength of the block framework can reach more than 5MPa, the density of the ultralight foamed concrete is controlled below 230kg / m<3>, and the ultralight foamed concrete has good insulating property. The apparent density of the self-insulating external wall block formed by the structures is only 480kg / m<3>, and the heat conductivity coefficient of the self-insulating external wall block is only 0.058W / (m*K). The self heat-insulating external wall block can lower the building load by more than 30%, can greatly save the consumption of reinforced cement, can reduce the construction cost by more than 20%, can achieve the requirement of building energy conservation by 50% or 65% without implementing internal and external insulating processes for the wall body, and can obtain large social benefit and economic benefit.
Description
technical field [0001] The invention belongs to building materials, and relates to wall block bricks used in residential buildings, in particular to a self-insulating outer wall block composed of a hard block skeleton and an ultralight foamed concrete insulation layer. Background technique [0002] At present, the country attaches great importance to energy conservation and improvement of living conditions, and building energy conservation is an important field of energy conservation work in our country. The National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Commerce, and the State Intellectual Property Office promulgated and implemented on January 23, 2007, in the "Guidelines for Priority Development of Key Fields of High-tech Industrialization", clearly stated that "priority development of high-tech industrialization Performance exterior wall self-insulating wall materials". The "Circular Economy Promotion Law of the People...
