Abstract
A synthetic aggregate having a multiplicity of uses such as for mixing with a cementing material to form concrete, mortar or plaster is disclosed. The aggregate includes crushed fragments of a size which are capable of passing through mesh screen having sieve openings ranging from between about 19 mm and 75 microns. The aggregate fragments are made by curing and then crushing a compressed product. The compressed product is made by compressing an aqueous cementitious mixture comprising cement and at least one member selected from the group consisting of bottom ash and non-cementitious fly ash. The compressed product is cured so that it has a compressive strength of at least 600 psi.
Claims23
An aggregate having a multiplicity of uses such as for mixing with a cementing material to form concrete, mortar or plaster, said aggregate comprising:
- crushed fragments having a particle size so as to pass through mesh screen having sieve openings ranging from between about 19 mm and 75 microns, said fragments being made by curing and crushing a compressed product which is made by compressing an aqueous cementitious mixture comprising cement and at least one member selected from the group consisting of bottom ash and non-cementitious fly ash and wherein said cured compressed product has a compressive strength of at least 600 psi.
