Retrofitting of RC Beams using0Self Curing Self Compacting Concrete

Abstract

The disposal of wastes from thermal, steel industries and from demolition of building is causing severe land pollution. About 5% of Global warming is caused due to production of cement and0by0using pozzalonic0materials0such0as Fly0Ash, GGBS, Silica fume, Metakaoilin and Alcoffine, by using such kind of mineral admixtures. These materials posses the cementitious property when mixed with water. In congested reinforcement conditions it is difficult to compact the concrete with a vibrator, hence self compacting concrete is used. Concrete is the most used material after water, but water is the most important ingredient for the production of concrete, due to the scarcity of water self curing compound is used for the production of concrete by replacing M-sand in place of natural river sand conforming EFNARC Codal provisions This study mainly focuses on the partial replacement of Cement by Fly ash and alcoffine at varied proportions by weight of Cementitious material for producing Self curing self Compacting Concrete. Mechanical properties at 3,7,28,56 and 90days will be done by casting. Validation of the test results will be obtained using Neural network and Mat labs To produce concrete with appreciative strength using different pozzalonic material and to Further experimental0investigation0is to0study0the0deflection and0crack0behavior0of RC0Beam0with0Fly0ash and0Alccofine will be done by casting number of beams of size 2800*150*300. Two methods of retrofitting methods such as CFRP Jacketing and Concrete jacketing will be done for the cracked beam and the ultimate load carrying capacity of CFRP Jacketing and Concrete Jacketing will be observed. To study the different retrofitting methods and comparing the values of CFRP and Concrete Jacketing.
