ABSTRACT:
A process for the production of a water-insoluble, abrasion-resistant, synthetic solid article or aggregate, as well as the products produced thereby. Fly ash, lime, water and FGD sludge are mixed intimately and formed at pressures exceeding 1,000 psi, preferably 4000-8000 psi. The product is cured for at least the equivalent of 28 days at 73.degree. F., and crushed and sized to produce a commercial aggregate, for example, for concrete, asphalt, concrete masonry units, etc.
