摘要

The manufacturing process of pozzolan residue of zinc, pozzolan residue of zinc and the use of such pozzolan.The present invention is a manufacturing process of pozzolan from residue of zinc and pozzolan thus obtained, a product especially with wide use in more diverse types of industries, such as construction industry, cement industry: as the material adici By the cement, mortar industry: as additional material to the mortar.The pozzolan is obtained by subjecting the residue of zinc from zinc ore mining process of calcination to form cut in a rotary furnace at temperatures ranging from 700 0C and 1000 0C, and then cooled and subjected to crushing, in order to obtain the final pozzolan.This product contains amorphous material which has the property of reacting with calcium hydroxide resulting from the hydration of clinker forming silicate hydrated silicates, further contributing to the quality of cement and mortar.
