Abstract
The present invention relates to Al-Si-Mg cement which is prepared from 100kg of magnesium oxide, 80kg of fly ash, 60kg of river sand, 80kg of 25 degree of magnesium chloride solution, 4.4kg of sodium silicate, 4.4kg of silicic acid collosol, 8.8kg of 18 degree of aluminium sulfate, 8.8kg of 28 degree of magnesium sulfate and 8.8kg of 30 degree of sulphuric acid to be mixed. The Al-Si-Mg cement can replace glass fibre reinforced plastic to produce various decorative materials, decorative boards, fire-proof boards, etc. and can be used as ordinary cement such as decorative members, light partition boards, roof tiles, etc. The cement has the advantages of light weight, high strength and smooth surface, and especially, the cement uses fly ash, so the environmental pollution caused by fly ash can be reduced.
Description
The present invention relates to a kind of cement, particularly relate to a kind of light weight, intensity height, cement that resistivity against fire is good.
Thermal power generation is still the main source of China's supply of electric power.The fuel of thermal power generation is coal, and a large amount of flyash will discharge every year in each big-and-middle-sized heat power plant, and these flyash are as can not fine comprehensive utilization meeting causing very big harm to environment, and this has been the fact of knowing altogether.Flyash has only the raw material of a small part as plastic window section bar at present, is not utilized greatly, and is polluting fine home.
Purpose of the present invention is at the problems referred to above, and a kind of Al-Si-Mg cement that utilizes industrial waste flyash to make main raw material is provided.
Above-mentioned purpose of the present invention is to realize by following technical proposals, that is:
Al-Si-Mg cement, be to be mixed to stir by flyash, magnesium oxide, magnesium chloride, water glass, silicic acid sol, Tai-Ace S 150, sal epsom, sulfuric acid, river sand to be mixed with, its ratio of components is: magnesium oxide 100kg, flyash 50-100kg, river sand 0-100kg, 22-29 degree magnesium chloride solution 70-100kg, water glass 4-6kg, silicic acid sol 4-6kg, 18 degree alum liquor 7-15kg, 28 degree Adlerika 7-15kg, 30 degree sulfuric acid 7-15kg.
The production method of Al-Si-Mg cement:
By ratio of components get magnesium chloride, water glass, silicic acid sol, Tai-Ace S 150, sal epsom, that sulfuric acid is put into container for stirring is evenly standby.Get flyash, magnesium oxide and river sand by ratio of components, put into stirred pot, prepare standby solution and put into stirred pot above-mentioned again, mix, stir, be finished product.
Al-Si-Mg cement is a thick porridge shape thing.
The alternative glass reinforced plastic of Al-Si-Mg cement is made various finishing material, and dalle, fire-proof board, air conditioner ventilation road etc. also can be made Portland cement and use, as manufacture product pipeline, decoration element, light partition board, roofing tile etc.
Al-Si-Mg cement has lightweight, intensity height, smooth surface exquisiteness, has particularly used a large amount of flyash, helps total utilization of PCA and prevents the pollution of flyash to environment.
