This paper presents an experimental investigation on the durability characteristic of concrete made with marble powder as partial replacement of cement by various percentages like 0%, 5%, 10%, 15%, and 20% on the properties of M25-grade of concrete, when it is subjected to various weathering agencies. Concrete specimens of size 150 x 150 x 150 mm were casted and cured as per IS specification to find the durability of concrete. In order to find the durability characteristics of concrete we performed many tests, like water absorption test, water permeability test, hydrochloric acid attack (HCl), sulphate attack iy(MgSo4) and chloride attack (NaCl). For the acid attack tests the concrete specimens were kept immersed in 5% concentrated acid solution of, hydrochloric acid(HCl) with water, magnesium sulphate (MgSo4) with water, and sodium chloride(NaCl) with water for 90 days for observation. Before immersion of the specimens, they were weighed accurately and after required days of immersion and observation, the specimens were removed from acid solution. Then the specimens were weighed accurately and weight loss and hardness of concrete were studied. The various results which indicate the produce of replacement of cement by marble powder on concrete are presented in this paper to draw useful conclusions. The results were compared with the mix design of concrete of same grade(M-25). The test results indicate that use of replacement cement by marble powder has improved the durability of concrete at 20% of marble powder. But the test for water absorption and the water permeability of concrete also show the satisfactory results at 20 % marble powder.
