Strengthening of RC beams using glass fibre reinforced polymer sheets and nanosilica gel.

The most prevalent kind of flaw that may readily arise in concrete constructions is cracking, which can be caused by a variety of factors. Those fissures might potentially have an impact on the building's strength. In order to fix these gaps, it is necessary to locate a different source of supply. Materials such as GFRP Sheets and Nansosilica Gel have been selected for the objective of the inquiry being conducted. GFRP sheets are used for the aim of cost-effectiveness, and they are able to bear severe weights. As a result of its ability to fill minute holes, nanosilica gel has superior sealing properties. For the purpose of conducting an investigation, six rectangular beams with a cross section of 150x200 millimetres and a span of 1000 millimetres were cast using concrete of grade M25 and steel of grade Fe 500. For about 28 days, the cast beams are allowed to cure. The six beams are put through their paces after the curing procedure. As a control beam, the first two beams are selected once the testing has been completed. The next two beams are going to be coated with Nanosilica Gel, and the remaining two beams are going to be rolled and bound with GFRP sheets. In conclusion, a comparison has been conducted between the beams that are coated with Nanosilica Gel and the beams that are bound together with GFRP sheets. [ABSTRACT FROM AUTHOR]
