Claims
- 1. A resinous binder composition useful for preparing improved concrete and asphaltic products comprising a mixture of (1) a polyepoxide having an epoxy equivalency greater than 1.0, and (2) a curing amount of a curing agent comprising a liquid reaction product of methylene chloride and monoethanol amine.
- 2. A composition as in claim 1 wherein the curing agent comprises a reaction product of 5% to 20% by volume of monoethanol amine and 80% to 95% by volume of methylene chloride, the amount of the methylene chloride in the binder counting the units of the methylene chloride combined in the reaction product curing agent as well as any monomeric methylene chloride that may be present or added as a solvent being in excess of 40% by volume of the binder.
- 3. A composition as in claim 1 wherein the polyepoxide is a glycidyl polyether of a polyhydric phenol.
- 4. A composition as in claim 1 wherein the polyepoxide varies in amount from 20% to 70% by volume of the total binder.
- 5. A composition as in claim 1 which also contains a filler.
- 6. A composition as in claim 1 wherein the composition so contains finely divided aggregate.
- 7. A composition as in claim 1 wherein the composition also contains Portland cement.
- 8. A composition as in claim 1 wherein the composition also contains Portland cement, aggregate and sand.
- 9. A composition as in claim 1 wherein the composition also contains Portland cement, sand and water.
- 10. A composition as in claim 1 wherein the composition also contains tar sand as a filler.
- 11. A composition as in claim 1 wherein the polyepoxide is a glycidyl polyether of 2,2-bis(4-hydroxyphenyl)propane.
- 12. A hard insoluble infusible product obtained by effecting a cure of the composition comprising a mixture of a polyepoxide having an epoxy equivalency greater than 1.0 and a curing amount of a liquid reaction product of 5% to 20% by volume of monoethanol amine and 80% to 95% by volume of methylene chloride.
- 13. A hard insoluble infusible product as defined in claim 12 wherein the composition contains a filler.
- 14. A hard insoluble infusible product as defined in claim 12 wherein the composition to be cured contains Portland cement, sand and water.
