Use of Geopolymer Composites for Controlling Structural Cracks
Abstract: 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 …
