Abstract
Abstract A pozzolanic material-based coating and structural composition and method for forming into various forms. The components include: (a) water, (b) lime, (c) a majority of pozzolanic material, (d) a cross-linking agent (e.g. a fatty polyamide), and (e) an epoxy resin. When mixed with water the composition sets and hardens to form coatings and structures with good strength, adhesion, and flexibility. An optional fluidizing agent may be added to reduce the water requirements. The properties of the material may be varied by the addition of conventional fillers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
In a method for forming a pozzolanic materialbased coating and structural composition from 100-150 parts by weight of pozzolanic material, 3-20 parts by weight of liquid epoxy resin, 3-30 parts by weight of a polyfunctional crosslinking agent capable of forming chemical bridges between said pozzolanic material and epoxy resin, said agent comprising an organic compound including at least two amino and at least two carbonyl functional groups, 2-30 parts by weight of lime, and water, said pozzolanic material component comprising greater than 50% of the nonaqueous weight of said composition on a lime-free and filler-free basis, comprising the steps of (a) intimately mixing the polyfunctional cross-linking agent with a major portion of the pozzolanic material in an aqueous dispersion, and lime, (b) mixing the epoxy resin with the aqueous dispersion of step (a), and (c) permitting said mixture to set.
Claim 2
Dependent Claim
