The failure occurs on slant surface when the compressive strength of the repair materials are less than the compressive strength of substrate mortar. Print and complete the following astm c882 form.
If you need more info or have any questions, please note the Lab ID number and contact us at:. Instructions Submit 1 quart of product and desired application rate. Slant shear test method as per ASTM C standard is astm c882 used to measure the bond aztm of the repair astm c882.

The astm c882 method covers bonding hardened concrete to hardened or freshly-mixed concrete. The compressive c8822 of the repair material was determined at 28 days after casting the repair material specimens, while the corresponding compressive strengths of the substrate mortar were obtained at 63 days after casting the test specimens. The values astm c882 in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
A specific hazard statement is given in Section 8. However, it was observed through experimental studies that the failure on the slant surface is not necessarily the case with all the astm c882 materials.
In contrast, test astm c882 of repair materials cast alongside the composite cylinders exhibited a rapid gain in compressive strength, ranging from 31 MPa to 82 MPa 4, to 12, psi.
Historical Version s – view previous versions of standard. It was also observed astm c882 the failure of the composite cylinders occur on the astm c882, if the compressive strength of repair materials are lower than the compressive strength of the substrate mortar. The technical data sheet available for selection of these repair materials are mostly based on ASTM test procedures. This method evaluates bonding astm c882 mortar specimens to freshly mixed specimens. Figures 2 b and c show the failure of the composite cylinder in substrate and repair material, respectively, indicating a weaker material strength than the bond asttm at the interface.
Warning —Fresh astm c882 cementitious mixtures are caustic and may cause chemical burns to zstm skin and tissue upon prolonged exposure.
The bond strength is determined by using the epoxy system to bond together two equal sections astm c882 Portland-cement mortar cylinder.
The composite cylinders were tested for bond strength as per ASTM C procedure after 28 days of casting. Full text astm c882 ” 1. Effect of Differences in Compressive C82 Table 1 shows the compressive strength of substrate and repair materials, and the bond strength of the repair materials.
It was observed that in the subsequent 28 days during which the composite cylinders were cured, the substrate mortar registered only an additional 6. This research, investigates the influence of compressive strength on the bond strength of the repair materials. This paper investigates the influence of compressive strength of repair materials and substrate mortar on the failure astm c882 of the composite cylinders and astm c882 that compressive strength of repair materials influence the failure pattern ast bond strength of repair materials.
Evaluation of test methods for measuring the bond strength of portland cement based v882 astm c882 to concrete, Cement, Concrete and Aggregate 1 1 pp. Results Produced Bond strength, bond area, voids in the astm c882 and type and position of the failure are reported.
The experimental program consisted of casting 24 substrate mortar specimens in 76 mm 3-in. However, performance of satm materials has shown that this test method does not adequately astm c882 the true bond strength of the repair materials due to some inherent shortcomings.
A modified slant shear test designed to enforce adhesive failure, Construction and Building Materials 41, pp 7. The details of these tests are provided in the astm c882 section.
Order Form 2 Email complete form to contact listed astm c882. Work Item s – proposed revisions of this standard.
The bond strength calculated based on this test procedure assumes the failure of the composite cylinder occurs preferentially astm c882 the slant surface.
The molds shall be constructed in the form of right cylinders. Search the history of over billion web pages on the Internet. astm c882
Apparatus to mix C828 mortar shall be as described, except for the sections on specimen molds, tamper, and testing machine. In this study, two classes of astm c882 strength – Minimum bond strength as calculated based on ASTM C and Actual Bond Strength – are recognized for sake of clarifying the mode of failure.
