In general the Geo-polymer concrete results obtained from the reaction of a source material i.e. high in silica, alumina and with alkaline liquid. The word geo-polymer was coined by Davidovit’s. Geo-polymer substances lately described as being acid resistant. This present paper studies the experimental investigation data on the Behavior of fly-ash based geo-polymer concretes replaced in chemical solutions for up to four weeks. The fly-ash deployed geo-polymer concrete was at first restored (cured) for 24 hours at 60°C. And also the attained results are comparison with the conventional concretes replaced to 5% acid solutions for up to four weeks. Of The attained compressive strength of geo-polymer concretes and conventional concretes cubes of 150-mm @ an age of 4 weeks are 31.9MPa and 48.4MPa. At first concrete cubes were restored for a period of 4 weeks and after cubes were submerged in chemical solutions, After immersion in chemical solutions, samples were tested at an age of 1week, 2 weeks and 4 weeks. In this work compressive strength and the weight loss reduction were determined. In this experimental investigation three types of chemical solutions are utilized that are HCl, H2SO4 and MgSO4. The test results shows that the Geo-polymer concrete is more resistant to acid and having low loss of weight and compressive strength when compared to conventional concrete
