The present work aims to use different waste materials, such as fly ash, industrial waste pond ash, rubber crumbs from rubber tires, recycled coarse aggregate from building waste. In doing so, the goal of reducing building costs will be achieved and can help to solve the issues connected with its disposal, particularly the environmental concerns of the area. Throughout this project, Rubber Crumbs (RC) and Recycled Coarse Aggregate (RCA) were partly substituted instead of coarse aggregate with a percentage of 10, 15, 20, and 5, 10, 15, which were found to improve the flexural strength of concrete. Such products may also be used for renewable building purposes. Keywords: Geopolymer, fly ash, GGBS, Pond ash, Recycled Coarse aggregate, Rubber Crumbs, Expanded Polystyrene I. INTRODUCTION Concrete is a construction substance composed of a fine and coarse aggregate, confined to a fluid material that solidifies after some period. Concrete production is not environmentally sustainable and thus alternate, environmentally safe products are defined for use in concrete. Extensive work has been carried out across the globe to find an effective binder to partly or fully substitute for cement. The challenge or issue is that cement is an active hydraulic a system that can react directly with water to create hydration products. To express these binders, Davidovits formulated the term 'Geopolymer.' The issue of waste management is growing severe. There is a lot of toxic waste whose capacity has not been recognized and is being lost in vain. We ought to figure out their ability and utilize them without dumping. Waste products developed by manufacturers in different ways, such as fly ash, pond ash, etc., may be used as resource-saving concrete structures and can also help to address the issue of waste disposal. Owing to its non-biodegradable nature, the waste tires contained have been a point of concern for various solid wastes. Manuscript received on May 25, 2020.

Building and demolition waste contributes up to 40% of all waste produced worldwide. The recycled aggregate is used as the most fitting substitute for the normal, coarse aggregate. Geopolymer concrete utilizes amorphous glassy alumina silicate mineral compounds enabled by alkali actuators to create long-chain sialates through polymerization to shape a binder to eliminates the motion of cement. The benefit of this form of concrete is that no water is needed for curing and cures at ambient or elevated temperatures. In all realistic uses, the geopolymer concrete may be used. The process is conducted at room temperature by incorporating mixtures. The replacement of rubber crumbs up to 5 percent contributes a reasonable compression strength, underlined by Z Yahya et.al (2018). As the proportion of rubber crumbs rises, their strength appears to decrease. Weight gain in marine exposure for all geopolymer samples. The higher rubber crumb content increases the geopolymer porosity and results in an increase in sample weight and decreases the strength. The impact of recycled coarse aggregates decreases the slump value by rising the amount of the RCA, Saravanakumar (2018) has concluded. The recycled coarse aggregate of the geopolymer showed greater strength than the standard recycled coarse aggregate. RCA substitution provides reasonable strength in comparison to geopolymer concrete up to 20 percent. R. Vandhiyan et.al (2016) investigated how an increase in concrete mixed EPS bead levels reduces the strength of the concrete compressive, flexural, and tensile. All EPS concrete without any special bonding agent has good workability and can be easily compacted and finished. The EPS efficiency level is 10%. With an increase in the percentage of EPS beads, concrete density was decreased. It also suggested that expanded polystyrene concrete has potential for non-structural uses, such as wall panels, partition walls, etc. Dr. R. N. Krishna (2014) claimed that geopolymer concrete has a slump value greater than Portland cement concrete. Extended polystyrene and glass fiber application reduces concrete workability. Increased sodium hydroxide concentration leads to increased compressive strength when exposed to the ambient treatment. In contrast with ordinary Portland cement, the flexural strength of geopolymer concrete with glass-fiber and polystyrene treated was improved. The temperature in the geopolymer mass formed is constant (S. Vaidya et.al (2011)). For an improvement of the durability, the compressive strength of the geopolymer concrete improved. The findings of the cylinder check demonstrate that during the mixing of additives the fresh geopolymer blend undergoes an exothermic reaction.
