COMPARISON OF RHEOLOGICAL AND MECHANICAL PERFORMANCES OF REPAIR MORTARS USED IN REPAIRING CONCRETE DEFECTS

Abstract

Concrete is a durable and long-lasting building material that has a wide range of uses in the construction industry. However, over time, various defects may occur in concrete structures due to various factors. These defects can threaten the safety and aesthetics of the structure and also require maintenance and repair. Among the defects seen in concrete, problems such as cracks, breaks, surface deterioration and water leaks come to the fore. Various repair techniques and materials are used in concrete repair, depending on the type and size of the defects and the intended use of the structure. One of these materials is "repair mortar". Repair mortar is a frequently preferred solution for repairing and strengthening concrete surfaces. These mortars are compatible with the natural structure of concrete and are formulated to ensure long-term durability of the repair. In this study, the effects of repair mortars from different manufacturers on the rheological and mechanical properties in the repair of concrete road defects were investigated. The research includes a systematic comparative evaluation of materials commonly used in the market and aims to provide scientific data for material selection. Within the scope of the methodology, basic properties of repair mortars such as fluidity, setting time and strength were measured in a laboratory environment and compared with manufacturer declarations. The results revealed that the repair mortars examined complied with the technical specifications and supported that these materials are effective and reliable solutions in concrete road repair.
