Study of Crack Repair in Reinforced Concrete Structures Using Suitable Materials

Abstract

Out of numerous serious problems that occur in reinforced concrete, formation of cracks and their propagation has its own say. Different types of cracks can form due to numerous reasons which include reinforcement corrosion, environmental effect, load impact and settlement of framework which can then affect the useful lifetime of any structure hence making the reinforced concrete structure less durable. Crack repairs, with the help of suitable materials, need to be done in order to reinstate the original strength of the structure. Water penetration test besides compression test were used to study the effectiveness of different materials used for repair work in current study. Results elaborated that polymer injection with materials available in local market can restore the actual strength of reinforced concrete elements and works more effectively as compared to other additives. It was found out through Water penetration test that water resistance was shown by all polymer injection materials.
