Standard Test Method for Bond Strength of Epoxy-Resin Systems Used With Concrete By Slant Shear

Significance and Use

The strength developed by a bonding system that joins two regions of concrete is its most important property.

Abstract

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.

Scope

1.1 This test method covers the determination of the bond strength of epoxy-resin-base bonding systems for use with portland-cement concrete. This test method covers bonding hardened concrete to hardened or freshly-mixed concrete.

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this test method.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in Section 8.
