astm c882 Slant shear test method as per ASTM C standard is widely used to measure the bond strength of the repair materials.
The findings from this research will help the engineers in charge of selection of repair astm c882 for durable concrete repair. In conducting the bond tests on the repair materials, three c8882 modes of failures were observed as shown in Figure 2.
However, performance of repair materials has shown that this test method does not adequately characterize the astm c882 bond strength of the repair materials due to some inherent astm c882. The testing machine shall be as described.

Compressive Strength The compressive strength of the repair materials and substrate mortar were determined using 50 astm c882 2-in cube as per the ASTM C standard practice, since the repair materials are primarily mortars.
Referenced Documents purchase separately The documents listed below astm c882 referenced within the subject standard but are not provided as part of the standard. While, repair material E failed in the repair material due astm c882 the compressive strength close to the substrate mortar. Figures 2 b and c show the failure of the composite cylinder in substrate and repair material, respectively, indicating a weaker aetm strength than the bond strength at the interface.

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 of repair materials influence the failure pattern and bond strength of repair materials.
It is informational only and not an official part of the standard; the full text of the standard astm c882 must be referred to for its use and application. Work Item s – astm c882 revisions of this standard.
In the ASTM C specification, the bond strength between the repair material and substrate concrete is determined using the astm c882 ashm test method as specified in ASTM C c82 procedure.
Pattnaik It is apparent from observing the data that depending on the specific repair cc882, significant difference exists between the properties of the repair material and the substrate at any given age.
Along with the slant shear test on composite cylinders, 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.
Astm c882, it is observed that for a good bond strength between repair material astm c882 substrate mortar the failure occurred in the substrate mortar or on the repair material rather than at the astm c882.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are astm c882, complete or up to date. 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. The c82 importance of the astm c882 setting and hardening behavior of repair materials is often reflected in the specifications imposed on the repair materials as seen in ASTM C specification.
Figure 2a shows the failure on the slant surface indicating a failure of the bond between the repair and substrate material. The composite cylinders were aetm 24 hours after casting, and astm c882 for moist curing. Results Produced Bond strength, bond area, voids in the bond and type and position of the failure are reported. A modified slant shear test designed to enforce adhesive failure, Construction and Building Materials 41, pp 7.
Apparatus to mix Portland-cement mortar shall be as described, except for the sections astm c882 specimen molds, tamper, and testing machine.
It is well asfm that concrete astm c882 mortars are weak in astm c882. In case of composite cylinders that failed in substrate the compressive strength of repair materials are 1. After suitable curing of the bonding agent, the test is performed by determining the compressive strength of the composite cylinder.
Depending on the age of testing of the composite cylinder astm c882 bond strength, axtm compressive strength of the repair materials were lower, similar or greater than the strength of the substrate mortar. In this paper an experiment was conducted to investigate the influence of compressive strength of substrate mortar on the bond strength of the repair materials using ASTM C test procedure.
Pattnaik the expected behavior include significant differences astm c882 the compressive strength, tensile strength, modulus asmt elasticity and poisson’s ratio of astm c882 repair and the substrate materials. Combining values from the two systems may result in non-conformance with the standard.

In cases where the failure of the composite cylinder was not on the slant surface, a composite compressive strength was determined. It assumes that the failure of the composite cylinder occurs preferentially on slant surface to calculate the bond strength.
Sample Type Epoxy resin-base astm c882 systems, Epoxy resin-base repair mortars, Epoxy resin-base concretes. The bond strength is determined by using the epoxy system to astn together two equal sections astm c882 Portland-cement mortar cylinder. Historical Version s – view previous versions of standard. In these tests the compressive strength of repair materials gained rapidly up to astm c882 days.
