Title: METHOD FOR THE HANDLING OF ASH CLASSIFIED AS WASTE, A PRODUCT FORMED WITH SAID METHOD AND USE OF SAID PRODUCT
Abstract:
The object of the invention is a method for the handling of ash classified as waste. The ash is sorted when dry according to grain size and is formed for use as an additive either in the manufacture of cement, concrete, asphalt, fertilizer, panel products, building components and/or grouting material and/or in earthworks, in soil reinforcement, in the stabilization of a road bed and other land areas, or in mine fill. Ash sorted by grain size to be suited to purpose is selected as a filler product, into which is mixed waste gypsum or other additives according to need. When manufacturing an additive for the stabilization of a road bed and other land areas, it is advantageous to use ash derived from wood combustion as the ash. The invention also relates to products manufactured with the method and to the use of said products.
