ABSTRACT
This project is carried out to know the effects of salt water on concrete. Salt water has salinity of about 3.5%. in that, about 78% is sodium chloride and 15% is chloride and sulphate of magnesium. The result gotten from the experiment being carried out shows different result from the mix design, casting, curing and crushing of different dates of each cubes. The compressive strength of each cube was also determined e.g. for the compressive strength of mix design 1.2.2:4 for both salt water and fresh water for different days such 7,14,21,28 days are “for fresh water” 26.0N/mm2, 33.1N/mm2, 3.8.4N/mm2, 4/06N/mm2 “for salt water” for different days such as 7, 14, 21, 28days which results are 25.9N/mm2, 28.3N/mm2, 36.3N/mm2, 38.9N/m. For compressive strength of Design Ratio “1:1:5:3:3” for different days such as “7, 14, 21 and 28 days respectively which are “43.3N/mm2, 47.7N/mm2, 48.4N/mm2, 47.3N/mm2 for fresh water and that of salt water are as follows, 42.1N/mm2, 44.9N/mm2, 46.3N/mm2, 47.26N/mm2. For mix design ratio “1:3:3:5:8” we have their compressive strength to be 16.3N/mm2, 21.8N/mm2, 25.03N/mm2, 29.6N/mm2 for each respective days for fresh water and that of salt water to be 16.2N/mm2, 20.3N/mm2, 23.57N/mm2, 27.6N/mm2, which also helps in the plotting of the graph of compressive strength against the curing days, to determine the strength of each cube.
