Use of Geopolymer Composites for Controlling Structural Cracks

A building's safety and stability can be compromised by ignoring the potential structural issues indicated by occurring cracks in buildings. Extensive damage may cause over the period from unidentified cracks.. Good quality concrete never cracks in normal service conditions unless high horizontal force is applied. Through the cracks, carbon dioxide is released into the concrete and speeds up carbonation throughout the cracks, thus reducing the structure usage. The materials which are involved in construction, diminish due to chemical reactions. The common kinds of chemical reactions in building materials are carbonation in cementitious materials, alkali-aggregate reaction, sulfate attack on cement products, and corrosion over reinforcement in concrete. Concrete may crack due to expansive reactions between aggregate, which accommodate alkaline derived and active silica from cement hydration. This paper describes Glass Fibre fiber-reinforced polymer as the best remedial material for structural cracks. Geopolymer may be used to repair structural defects by several procedures, including patching, spraying, and injecting. The repairs are often durable making them a dependable alternative for restoring structural integrity. This paper focuses on the chemical reaction's role in the formation of structural cracks and the use of geopolymer composites for remedial measures. This article is very beneficial to be aware of the identification of unaddressed cracks due to chemical processes and the economic measures to prevent structural integrity and stability.
