In the world, concrete is the material that is most frequently used for construction. Portland cement consumption increases as a result of the increased demand for concrete as a building material. An environmentally friendly alternative to regular Portland cement is geo-polymer. By combining ingredients like fly ash, grounded granulated blast furnace slag (GGBS), fine aggregate, and coarse aggregate with sodium hydroxide solution, sodium silicate solution (NaOH and Na2SiO3), or potassium hydroxide, potassium silicate solution (KOH and K2SiO3), it is possible to create geo-polymer concrete that is then properly cured. Alkaline liquid is a mixture of sodium hydroxide solution and sodium silicate solution. This study's research focuses on substituting the fine aggregate material in geo-polymer concrete with Msand. Complete 100% replacement of natural sand with manufactured sand and compare the results witch GPC natural sand and GPC witch Msand and its durability. When exposed to sulphate, and acidic environment and assessment were made with normal Ordinary Portland Cement (OPC) concrete. In total four tests were conducted to determine acid and sulphate resistance of geo- polymer concrete witch Msand. The tests involved concentration for a period of 30 to 60 days into 5% solution of sodium sulphate, 5% solution of magnesium sulphate, 5% solution of sulphuric acid and 5% solution of phosphoric acid. The progression of weight loss and compressive strength loss were studied. The most major degradation of compressive strength and weight were determined in 5% of acid solution. The minimum strength dissimilarity and weight loss were found in the 5% of sulphate solution. The Ordinary PC concrete deteriorated more in acid as well as in sulphate solution in compared with geo-polymer concrete, thus geo-polymer concrete is more durable than the OPC concrete.
