Book Description
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.

Book Description
Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities.Specialist techniques and materials for concrete construction forms the Proceedings of the three day international conference held during the Congress, creating with concrete, 6-10 September 1999, organised by the Concrete technology unit, University of Dundee.

Book Description
This study was conducted to identify methods that have been used in the repair and rehabilitation of concrete dams. Information was obtained through literary searches, discussions with project personnel, and visits to project sites. Each case history includes a background of the project, the deficiency that necessitated repair or rehabilitation, and descriptions of materials and methods used in the repair or rehabilitation. When available, the cost of the repair project and the performance of the repair to date have been included. Case histories included in this report cover a range of deficiencies in concrete structures, including cracking, spalling, erosion, leakage, inadequate PMF capacity, expansion resulting from alkali-aggregate reaction, instability, and insufficient storage capacity.
