Embodiment 1

[0017] The proportioning by weight of this example raw material component is as follows:

[0018] Steel-making high-temperature furnace waste slag fiber cotton: 5 parts,

[0019] Silica fume: 1.5 parts

[0020] Natural pumice wool: 2 parts

[0021] Cement: 2 parts.

[0022] The waste slag fiber cotton of the steelmaking high-temperature furnace is a kind of waste slag flowing out from the high-temperature furnace, and its bulk density is required to be 600 kg / m 3 The following is to ensure the lightness of this raw material; the silica fume is a kind of dust recovered from industries such as metallurgy, and it is required that the silicon dioxide contained in the silica fume should be more than 70%, and its bulk density should be 280 kg / m 3 Hereinafter, to ensure the thermal insulation performance and light weight of this raw material; the natural pumice velvet is natural pozzolan, which is available in the market; any cement sold in the market can be used for cement. Then...

Abstract

The invention relates to an automatic heat-insulation building block for an outer wall, which is prepared from 4 to 5 parts of slag cellucotton of a steel smelting high-temperature furnace, 1.5 to 2 parts of silicon ash, 2 to 3 parts of natural pumice stone cotton wool and 1.6 to 2 parts of cement according to the technology of concrete hollow building blocks. The invention uses two industrial waste materials and one natural material as heat insulation materials which have the characteristic of low heat conduction coefficients and account for more than 80 weight percentages of the total weight of the material, thus, the invention has excellent heat insulation performance, and the slag cellucotton of a steel smelting high-temperature furnace has excellent strength and can form skeleton support in the finished product to enable the finished product to have excellent pressure resistant strength. Because 55 percent to 60 percent materials of the automatic heat-insulation building block are industrial slag, the material cost can be greatly lowered. In material selection, the invention avoids the material with high volume weight, thus, the invention also has the characteristic of light weight. Detection shows that the invention has the heat conduction coefficient of 0.076 W / m*k and hihg cost performance.

Description

technical field [0001] The invention relates to a self-insulating building block for an outer wall, in particular, it is a self-insulating building block for an outer wall made of industrial waste. Background technique [0002] In recent years, building energy conservation has become an important aspect of my country's implementation of energy conservation and emission reduction measures. At present, the external wall masonry materials used in northern my country require their energy-saving effect to reach 65%, which puts forward higher requirements for the thermal insulation performance of external wall masonry materials. At the same time, the performance and index of the material in terms of strength, light weight, and convenient construction cannot be reduced. This poses a severe challenge to the development of external wall insulation, because wall insulation and its strength, light weight, and construction are often incompatible. Conflicting. In the prior art, Chinese p...
