RESEARCH OF WATER ABSORPTION OF GEOCONCRETES ON BASIS OF WASTE OF IRON ORE ENRICHMENT AND BOTTOM ASH

Abstract

Specimens of geopolymeric concrete on basis of waste of iron ore enrichment of Dashkesan’s deposit and bottom ash of combustion of domestic waste were obtained. Herewith ratio of waste mixture to binder made up 80:20. At obtaining of geoconcrete specimens the concentration of bottom ash in waste mixture was variated in limits of 10-50%wt. Normality of water solution of alkali activator was variated from 1N up to 8N. Maximal values of water absorption of geoconcrete specimens containing 10, 20, 30, 40 and 50%wt of bottom ash correspondingly made up 9,9, 12,3, 11,9, 12,8 and 16%. Keywords: geopolymeric concrete, enrichment waste, iron ore, bottom ash, water absorption.
