Abstract
With coal gangue substitute for clay production road cement, coal gangue is one of main food ingredient of road cement, by Wingdale, coal gangue, sandstone, iron powder, hard coal, fluorite, after fragmentation, fit in raw material, after grinding, calcining, become the road cement grog again, the active addition and the gypsum that add appropriate amount again are behind grinding and become the gelling material with hydraulicity---road cement.Advantages such as this cement has the label height, sclerosis is fast, abrasion resistance is good, contract with dry rate is little, folding strength and anti-freezing property are good, therefore it is highly suitable for the construction of motorway, common road, airstrip, but also be applicable to Highrise buildings, of many uses.
Description
The present invention relates to a kind of prescription of producing silicate road cement or normal silicate road cement with the coal gangue substitute for clay.
Silicate road cement or normal silicate road cement, it has good wear resistance, frost resistance, less contract with dry rate and shock resistance.At present, obtained in the expressway construction at home and abroad using widely.But, in the batching of producing the silicate road cement, all add the silicate component of the clay of significant proportion, and the use clay has constituted the destruction to the soil as the silicate road cement, produce totally unfavorable to developing agricultural.
The purpose of this invention is to provide a kind of prescription with coal gangue substitute for clay production road cement, the protection good farmland alleviates the pollution of industrial residue to environment.Increase economic benefit of enterprises.
The coal gangue substitute for clay is produced road cement, be as one of main food ingredient of road cement raw material with the waste residue-coal gangue of coal-mining industry, add an amount of siliceous correction material simultaneously, be made into the raw material of proper composition, in mechanized cement shaft kiln, form silicate road cement grog through high-temperature calcination.The active addition and the gypsum that add appropriate amount again are behind grinding and become gelling material-silicate road cement or the normal silicate road cement (abbreviation road cement) with hydraulicity.
