Study On Flexural Behavior of Light Weight Green Concrete Beams

The increasing quantity of waste materials and industrial by- products is a major concern in the world today. The disposal of these by-products is becoming a big issue, because of the expense of disposal. Foundry Sand is a form of fine aggregate that is often used in hand and machine-made moulds. There is a strong desire to discover an alternative method of disposing of Foundry sand(FS) while also limiting the use of natural resources. So Fine aggregate is partially substituted with foundry sand in this experimental work in order to produce green concrete (GC) Light weight concrete is one of the initiatives attempted to lower the self -weight of concrete. The study focused on the strength characteristics of concrete when pumice aggregate was used as a partial replacement for coarse aggregate. Various strength tests are conducted by partially replacing coarse aggregate with pumice stone by 20%,25%,30%,35% and 40%. Light weight green concrete(LWGC) is made by partially replacing fine aggregate by foundry sand(20%) and coarse aggregate with 25% pumice stone. The findings suggest that Foundry Sand(FS) can effectively replace fine aggregate and pumice stone(PS) can effectively replace coarse aggregate to produce Light weight green concrete
