Annotation

This test method covers the determination of the bond strength of epoxy-resin-base bonding systems for use with Portland-cement concrete. The test method covers bonding hardened concrete to hardened or freshly-mixed concrete. The bond strength is determined by using the epoxy system to bond together two equal sections of Portland-cement mortar cylinder. After suitable curing of the bonding agent, the test is performed by determining the compressive strength of the composite cylinder. Apparatus to mix Portland-cement mortar shall be as described, except for the sections on specimen molds, tamper, and testing machine. The molds shall be constructed in the form of right cylinders. A dummy section shall be machined of a hard material that is not attacked by Portland-cement mortar. The testing machine shall be as described. Laboratory conditions, materials, proportions, and procedures for mixing the Portland-cement mortar shall be tested to meet the requirements specified.
