Abstract:
A method for accelerating the strength of cement involves providing an activated fly ash processed to increase the surface area of the fly ash and reacting the activated fly ash with a polycarboxylate heteropolymer that acts as a catalyst to produce a pozzolanic cementitious material having as much as a 28% increase in strength (e.g., compressive strength). In one embodiment, the heteropolymer includes hydrophilic and hydrophobic components that assist in providing an optimal equilibrium for the formation of cementitious structures. The increase in strength permits reducing the amount of Portland cement mixed with the pozzolanic cementitious material to as little as 30% by weight, thus achieving a significant cost reduction.

Claim (Index 1):
A method of making a pozzolanic cementitious material, the method comprising:\n providing an activated fly ash that has been processed to increase a surface area thereof; reacting a polycarboxylate heteropolymer high-range water reducer with the activated fly ash, wherein the polycarboxylate heteropolymer high-range water reducer comprises a hydrophilic component and a hydrophobic component that provide for a water-to-cement ratio of the pozzolanic cementitious material which:\n is unaltered despite the presence of the polycarboxylate heteropolymer high-range water reducer; and \n provides for formation of cementitious structures without removing water; and \n mixing the activated fly ash and the polycarboxylate heteropolymer high-range water reducer with ordinary Portland cement.
