Abstract: Cement is an associate environmentally venture some material as a results of cement production is very energy and fuel intensive, making it the third ranking producer of inexperienced house gas emissions. Cement production is increasing by more or less 5 percent a year, making it one of the for most environmentally assist in making concrete a extremely eco-friendly material. The mixture of cement with totally different mixture materials is that the first reason that concrete cannot bear associate eco-friendly label. The heating and combination technique wants giant amounts of energy and emits atrocious amounts of inexperienced house gas in the atmosphere. Trying to combat the quality of green house gases discharged as a by-product of the concrete trade, in experienced innovators have fictional cement substitutes and totally different methods to form loads of earth–friendly product. Throughout this analysis, geopolymer concrete is utilized as an Eco-friendly concrete and recycled waste is used as another coarse mixture. In geopolymer concrete preparation, NaOH of 8 molarity concentration is used. Beam size of 125 mm × 200 mm × 1100 mm are cast to study the flexural behaviour. The beams are designed as under reinforced sections. Totally six beams are cast for M 20, M 40 and M 60 grade with crushed stone as coarse aggregate and with recycled glass as coarse aggregate. Out of six beams, three beams are made with stone aggregate and another three beams are made with glass aggregate. Beams are tested under two point loading for flexure. The ultimate load carrying capability of all beams is obtained. The crack and deflections of the beams are studied. The experimental results are compared with finite element modeling using ANSYS software.
