摘要
In a method of processing sulphur-contaning residue and fly ash into cured granules, the residue is mixed with fly ash and water to make a mixture, the mixture is granulated and the granules are heated to effect curing. In the granulatable mixture, the amount of fly ash is not more than 20% by weight relative to the total amount of said fly ash and the residue. A cementless mortar is made from fly ash, by mixing fly ash with [chalk] lime and other components to form a mixture containing by weight (i) fly ash : maximum 85% (ii) optionally, an amount of sand not exceeding the amount of fly ash (iii) (chalk) lime : 6 - 12% (iv) other components : remainder, and maintaining the pH of the mixture in the range 12.8 - 13.4. This mortar and the granules are combined to make a building block.
