Book Description
This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given.

An Evaluation of Equipment and Procedures for Tensile Bond Testing of Concrete Repairs

Pages : 88
Book Description
If the durability of repaired concrete structures is a primary objective of any repair project, then every effort should be made to ensure adequate bonding between the repair and the existing concrete substrate. A total of 257 partial-depth cores in 77 experimental repairs were tested in Florida, Illinois, and Arizona in order to evaluate the effect of material properties and environmental conditions on the bond between repair and concrete substrate. Three pull-off testing devices were used to determine the bond strengths for each of the experimental repairs. In addition, the testing devices themselves were evaluated by analyzing the magnitude and relative precision of the pull-off strengths, modes of failure, and ease of use in an effort to identify a reliable and practical device for determining in situ tensile bond. The optimum depth of core drilling into the existing substrate was determined by comparing theoretical finite element analysis of failure zone stress distribution with measured test results.

Book Description
The study reported herein is part of an overall investigation to develop performance criteria for cement-based repair materials. In Phase I of the study, preliminary criteria for dimensionally compatible repair materials were developed based on a review of the literature. This review concentrated on identifying pertinent material properties, appropriate test methods, and demonstrated field performance. Laboratory and field tests to evaluate the preliminary performance criteria were conducted in Phase II of the project Twelve candidate repair materials were selected for the experimental portion of the project Bach material was subjected to a series of standard and nonstandard laboratory tests to determine properties which were perceived to be of interest in a repair context and to provide some basic information about their behavior. These tests included: (a) unrestrained and restrained drying shrinkage, (b) modulus of elasticity, (c) tensile and compressive creep, (d) coefficient of thermal expansion, and (e) flexural, compressive, and direct tensile strengths. Concurrent field tests were also conducted to evaluate material durability. Results of the laboratory investigation are described herein. Results of laboratory and field performance tests will be correlated (Phase III) to provide a basis for development of performance criteria for cement-based materials that will provide durable concrete repairs.
