EFFECTS OF ACIDS AND BASES CONTAMINATION ON SOIL PROPERTIES IN PAVEMENT CONSTRUCTION

With the advancement of science and technology, the growing population and the demands of the people has led to a new era of industrial advancements. The number of industries and factories have grown rapidly. Though the industries proves to be useful to the people in many ways providing opportunity for employment and consumers product, it also has a serious impact on the environment. Industries releases a variety of pollutants into the soil thereby contaminating the soil. Such effluents consists of acids and base wastes. Due to this the geotechnical property of the soil gets altered. The study is carried out to determine the effects of acids and base on the properties of the soil. This is carried out by adding the contaminants to the soil in laboratory and the properties of soil such aspH, Atterberg's limits test, differential free swell, specific gravity, CBR tests are studied. The acids and base contaminants used are sulphuric acid, hydrochloric acid, potassium hydroxide and sodium hydroxide. The test is carried out by varying the percentages of the contaminants for 5%, 10% and 15%.
