Title: Evaluating Cracking Sensitivity of Repair Materials
Appears on pages(s):
Abstract:Cracking in the repair phase of the composite repair system is among the most serious causes of concrete repair failures. There are no presently generally accepted test methods to determine the long-term performance of a material to be used for surface repairs, no standards for the performance
evaluation of repair materials, and no reliable basis to optimize the properties of repair materials. The most important of these properties are in all probability those related to the deformation: shrinkage, creep, modulus of elasticity and coefficient of thermal expansion. However, there is no agreement on the relative influence of each of these properties. Furthermore, there is insufficient field and laboratory data available, both on the properties of repair materials and on the performance of composite elements (made of repair material cast on an “old” concrete substrate) subjected to various types of exposure, to correlate any or a combination of these properties to observed long term field performance. The paper presents review of ongoing research study in which one of the primary objectives is to develop reliable techniques for evaluation of repair materials performance.
