        abstract = {— The manufacturing of Ordinary Portland cement (OPC) is done with very high consumption of carbon dioxide emission. To enhance durability in construction, this study investigates the replacement of cement with rice husk ash and silica fume with addition of polymer. Rice husk ash is generated by burning of husks of paddy which is an agricultural waste, very rich in amorphous silica. Silica fume is a highly reactive pozzolanic material. These materials were replaced with cement in different replacement levels (0-30%) combined in equal parts mix. Polymer was added in a fixed percentage of 10% of weight of cementitious materials, to improve microstructure and reduce permeability. Experimental study includes tests on physical strength on specimens like compressive, split tensile, flexural strength tests. And durability test done was alternate wetting and drying. Results indicated that the combined use of RHA and SF improved strength and durability, while polymer improved bonding. The optimum replacement level was identified at 10% for compressive strength and 20% for split tensile strength, beyond which strength reduction was observed. While for flexural strength test the optimum replacement level was observed at 30% replacement in which strength was gradually increasing at different replacement levels. In alternate wetting and drying, water absorption and cumulative dry mass loss after drying was checked after wetting and during cycle for 24 hours and best resistance was observed in cylinders,it showed low dry mass loss and less waster absorption with no visible deterioration. This study concludes that RHA-SF-polymer blender concrete is a sustainable.},
