Salt water has a 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 results from the mix design, casting, curing and crushing of different dates of each cube. 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 as 7,14,21,28 days are"for freshwater" 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 day 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....Preview Download Preview +Other Civil Engineering project topics and materials you might be interested in»Comparing the compressive strength of concrete made with sand as fine aggregate and with chipping dust as fine aggregate»The comparative study of the compressive strength of concrete made with granite to that made with river round stone (pebble) and local stone»The use of computer in civil engineering»Importance of timber in civil engineering construction»Construction and Installation of a Panel Door»Construction of wardrobe key study on wood work»Effect of street trading on traffic performance and control»Assessment of different types of foundation and their mode of construction»Comparison of soil bearing capacity of different locations in Imo state»Investigation into the suitability of sand and gravel materials commonly used in building construction»Investigating the effect of partial replacement of cement with eggshell powder in concrete production»An investigation in to the causes of cracks in building and possible solutions - a case study of Kukar Gesa community in Katsina metropolis»Suitability of available laterite material in Ilorin East local government area for road construction»Determination of the causes, effects of environmental pollution and its possible control within Kwara and Osun state»Model for prediction of rainfall intensity in Lagos
