Book Synopsis Evaluation of Polyester Resin, Epoxy, and Cement Grouts for Embedding Reinforcing Steel Bars in Hardened Concrete by : J. Floyd Best
Download or read book Evaluation of Polyester Resin, Epoxy, and Cement Grouts for Embedding Reinforcing Steel Bars in Hardened Concrete written by J. Floyd Best and published by . This book was released on 1990 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation of hydraulic structures usually includes removal and replacement of deteriorated concrete. Dowels are normally used to anchor the new concrete to the existing concrete and to position vertical and horizontal reinforcing steel in the replacement concrete. The purpose of this investigation was to evaluate the effectiveness of cement, epoxy, and polyester resin grouts used to embed reinforcing steel bars in hardened concrete under a variety of placing and curing conditions. The following parameters were determined for each grout: physical characteristics of the grouts; effects of temperature and moisture on early service performance; long-term pullout strength under varying curing conditions; creep strain of grout under sustained loading in both wet and dry environments; and effects of hole roughness and cleanliness on grout performance.

This book was released on 1998 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation of civil works hydraulic concrete structures such as navigation locks or stilling basins commonly involves the removal of defective concrete and replacement with new concrete. Steel reinforcing anchors are normally embedded into the base concrete to assist in the attachment of the base concrete to the new concrete. With respect to bonding the steel anchors into the base concrete, this investigation was conducted to evaluate the effectiveness of cementitious, vinylester and epoxy grouts in bonding embedment of the anchors. Tensile pullout and long-term creep strain tests were accomplished in this study in correlation with parameters for dry and wet environments and for bond maturity ages of 1, 3,7, and 28 days and 1 year. Tests results indicated all of the grout materials developed sufficient bond strength in pullout and creep tests for dry applications, with the exception of one epoxy material. However, for submerged applications, the epoxy grouts exhibited poor developed bond strength in both pullout and creep tests. As a result, particular caution is recommended for the application of epoxy grouts to embed steel anchors in hardened concrete under submerged conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Rebar-couplers that mechanically splice pairs of steel reinforcing bars, end-to-end are used regularly in reinforced concrete construction. Epoxy-bonded couplers are one available type, but have unique long-term performance considerations. The adhesive material used in these couplers is a two-part, field-mixed, ambient-cure epoxy system, originally designed for adhesive anchorage to concrete. Many of the adhesive systems used for anchorage to concrete, including the system used with adhesive-bonded couplers, are epoxy systems. The mechanical properties of these types of epoxies have been shown to degrade over time, in the presence of moisture. A variety of commercially available adhesive systems, for anchorage to concrete, were studied to assess their relative resistance to moisture-based degradation. The material properties of two of the adhesive systems, both epoxies, and the performance of the rebar-couplers were then measured over a fourteen-and-a-half-month period of exposure to a variety of environmental conditions, including water immersion at a range of temperatures. From these results, material degradation models were used to predict the properties of the adhesive over the service life of the rebar-coupler. A Finite Element Analysis (FEA) model was developed to simulate the tensile failure of the epoxy-bonded rebar-coupler system and correlate degrading adhesive material properties to changes in the coupler system's behavior throughout its service life.
