If the bond astm c882 the repair material and the substrate material is good to sustain the shear stresses generated on c8882 slant surface, then the astm c882 mode in the composite cylinder is dictated by the tensile strength corresponding to the compressive strength of the repair material.

Along with the slant shear aetm on composite astm c882, cubes prepared from the same batch of mortar and repair materials were tested to determine the compressive strength of the mortar and repair materials, respectively. Depending on the age of testing of the composite cylinder for bond astm c882, the compressive strength of the repair materials were lower, similar or greater than the strength of astm c882 substrate mortar.

While, repair material E failed in the repair material due asrm the compressive strength close to the substrate mortar. Figure astm c882 shows the failure on the slant surface indicating a failure of the bond between the repair and substrate material.

C882 the ASTM C specification, the bond strength between cc882 repair material and substrate concrete is determined using the slant shear test method as specified in ASTM C test procedure. This method evaluates bonding hardened mortar specimens to astm c882 mixed specimens. It was also observed that the failure astm c882 the composite cylinders occur on the interface, if the compressive strength of repair materials are lower than the compressive strength of the substrate mortar.

This test method covers the determination of the bond strength of epoxy-resin-base bonding systems for use with Portland-cement concrete. The values stated in each system may not be exact equivalents; therefore, each system shall be 8c82 astm c882 of the other.

However, a principal tensile stress astm c882 also exerted in a direction perpendicular to the applied compressive load.

The bond strength calculated based on this test procedure assumes the failure of the composite cylinder occurs preferentially on the slant surface.

The findings from this research will help the engineers in charge of selection of repair materials for durable concrete repair. This provided a means to evaluate the influence of the disparity of the astm c882 properties of the repair and substrate materials on the bond strength of the composite cylinder.

In contrast, test specimens of repair materials cast alongside the composite cylinders exhibited a astm c882 gain in compressive strength, ranging from 31 MPa to 82 MPa 4, astm c882 12, psi. Astm c882, performance of repair materials has shown that this asrm method does not adequately characterize the true bond strength of the repair materials due to some inherent shortcomings.

The astm c882 of the materials used in preparing the substrate mortar were based on a cement-to-sand mass ratio of 1: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as astm c882 of the standard.

When the compressive asrm ratio between repair material and substrate mortar is approximately 1. The experimental program consisted of casting 24 substrate mortar specimens in 76 mm 3-in.

Figures 2 b and c show the failure of the composite cylinder in substrate and repair astm c882, respectively, indicating a weaker material strength than the bond strength at the interface. Effect of Differences in Compressive Strength In order to investigate the influence of differences in compressive strength of the repair and substrate materials on the bond strength of the astm c882 material, composite cylinder specimens were prepared as per the ASTM C test method.

In this paper an astm c882 was conducted to investigate the influence of compressive strength of substrate mortar on the bond strength of the repair materials using ASTM Astm c882 test procedure. The composite cylinders with a given repair material were prepared on the day when the substrate cylinders were 35 days old 28 days moist cured and 7 days air -cured. In these tests the compressive strength of repair materials gained rapidly up to 28 days. A specific hazard statement is given in Section 8.

The details of these tests are astm c882 in the results section.

This paper investigates the influence of compressive strength of repair materials and substrate mortar on the failure pattern of the composite cylinders and observed that compressive strength astm c882 repair materials influence astm c882 failure pattern and bond strength of repair materials.

Slant Shear Bond Strength Testing Before the repair material was bonded to the substrate mortar, the slant surface of the substrate mortar specimen is prepared by sandblasting and dry brushing.
