Problems solved by technology

Many researchers have been trying to develop the application of fly ash in the construction industry, but due to technical bottlenecks, so far, a large amount of fly ash from thermal power plants has not been able to be used in large quantities, which seriously pollutes the environment. Area destroys land resources
[0003] In my country, the Ministry of Construction explicitly banned the firing of clay bricks decades ago, but with little effect and repeated prohibitions, it still occupies a place in the construction market; although the government has taken compulsory measures to demolish brick kilns, it cannot prevent the destruction of fields to build bricks and burn bricks. The reason is that clay bricks are cheap and profitable and builders are still using them

Abstract

The invention relates to a solar automatic temperature control foamed cement building block for construction and a production method thereof, which have the following technical essentials: firstly, respectively stirring and evenly mixing a certain amount of phase transition heat accumulation and heat insulation material, common portland cement, fly ash, cement reinforcing agent, complexing agent and a proper amount of water at normal temperature; then, keeping stirring and adding a certain amount of foaming agent; casing the mixture into a building block in a mold after being evenly mixed; andstacking and preserving the building block for 25-30 days to obtain a finished product. The volume weight of the foamed building block of the invention is 1030kg / m<3>, which is 1.75 times smaller than that of the clay brick, and the weight of the foamed building block is greatly larger than that of the clay brick; the dimension is stable; the compression strength is larger than 10MPa; and the heat transfer coefficient is 0.00188.7W / M<2>K. In the invention, the building block wall board which is 370mm in thickness has the heat insulation performance equal to that of the clay brick which is 1887mm in thickness, and all the indexes conform to the 1.5 level standard. The invention utilizes the fly ash to produce the foamed building block and fully utilizes the solar radiation energy to save the energy resources.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a solar self-temperature-controlling building cement foam block and a production method thereof. Background technique [0002] As we all know, clay bricks are a traditional building material used for building buildings and one-story houses. Since clay bricks are made by processing soil from farmland, they will inevitably occupy farmers and even destroy fields. With the development of society and the continuous progress of science and technology, in order to protect farmland, governments at all levels have implemented a series of incentive policies to encourage the use of reinforced concrete, inorganic and organic materials (such as: power plant fly ash) to replace clay bricks. Many researchers have been trying to develop the application of fly ash in the construction industry, but due to technical bottlenecks, so far, a large amount of fly ash from t...
