1018.01 Description
1.This Specification provides requirements for two-component, epoxy-resin bonding systems for use in non-load bearing applications and resin adhesives for application to Portland cement concrete.
1018.02 Material Characteristics
1.Epoxy-resin bonding systems sha ll conform to the requirements of ASTM C 881. Approved systems are show n on the Department’s Approved Products List.
2.The classification of Epoxy-Resin Bonding Systems is as follows: a. Type I - For use in non-load bearing applications for bonding hardened concrete and other material to hardened concrete. Type II For use in non-load bearing applications for bonding freshly mixed concrete to hardened concrete. Type III For use in bondi ng skid resistant materials to hardened concrete, and as a binder in epoxy mortars or epoxy concretes.
b.Grade 1 Low viscosity. Grade 2 Medium viscosity. Grade 3 Non-sagging consistency.
c.Class A For use below 40°F (4 C); the lowest allowable temperature to be defined by the manufacturer of the product. Class B For use between 40°F and 60°F (4 C and 15 C). Class C For use above 60°F (15 C); the highest allowable temperature to be defined by the manufacturer of the product. Class D For use between 40°F and 65°F (4 C and 18 C). Class E For use between 60°F and 80°F (15 C and 26C). Class F For use between 75°F and 90°F (24 C and 32C).
1018.03 Procedures
1.The compounds shall be of the type and grade specified in the contract or as directed by the Engineer.
2.The class of the compounds shall be selected for use according to climatic conditions at t he time of application.
3.All bonding surfaces shall be clea n and free of all oil, dirt, grease, or any other materials which would prevent bonding.
4.Mixing and application shall be in strict accordance with the manufacturer's instructions.
