The sediments are composed of a mixture of illite and also to preserve the land fill from the hazardous dumping of these industrial wastes.The coal ash used in this study was of fly ash and obtained by burning coal mined from Siderópolis/RS - Brazil. The burning was performed in an oven (FORNITEC) at a temperature of 973 K for 6 hours using a sample of coal with particle diameters from 150 to 300 micrometers. Zeolite A synthesisA synthetic Class C fly ash results from a substantially homogeneous blend of about 40-60% by weight of a Class F fly ash and about 60-40% by weight of cement kiln dust (CKD). This new fly ash can replace about 25-50% by weight of portland cement in conventional formulations with coarse and fine aggregate for making general purpose concrete and particularly ready-mix …In a different set of experiments,
