Laboratory and Field Evaluation of Required Material Properties for ConcreteRepairs

摘要

This study investigated the material properties necessary to ensure a successfulconcrete repair. The information and data contained in this report will assist in the preparation of a repair materials selection guideline, one that could aid engineers in the selection of the most appropriate repair material based upon the environmental conditions. The study consisted of both a laboratory evaluation program and a field evaluation program. The laboratory evaluation program identified and tested the most important repair material properties. The field evaluation program consisted of both a qualitative and quantitative evaluation of existing repairs throughout Texas. One of the primary objectives of the field visits was to investigate a wide range of typical repairs that can be expected in Texas. The two evaluation programs can be synthesized into a single set of material selection guidelines.
