In order to achieve the above aim, some laboratory test were conducted these tests include specific gravity, slump test, concrete compressive strength and flexural strength test. During the concrete production the water/ cement ratio was varied from 0.3 to 0.4 in step of 0.05 while the cement content was kept constant. For each water/ cement ratio, concrete was prepared and casted in 8nos of cubes mould out of which 4nos were crushed in 7days while the other 4nos were crushed in 28days. The same way was followed to cast concrete for flexural strength. After the analysis the result obtained showed that the slump test result for 7 and 28days are 0.3 60mm, 0.35 72mm, 0.4 90mm, this shows that there is an increase in water/ cement ratio will increase the slump value of concrete. Compressive strength result for 7 and 28days are 0.3 21.63N/mm2 and 26.62N/mm3, 0.35 21.88N/mm2 and 26.53N/mm2 and 0.4 19.21N/mm2 and 21.03N/mm2, the result shows that as the water/ cement ratio increase the compressive strength decreases. Flexural strength result for 7 and 28days are 0.3 0.77N/mm2 and 0.84N/mm2, 0.35 0.7N/mm2 and 0.75N/mm2 and for 0.4 0.6N/mm2 and 0.73N/mm2 respectively. Finally, the result shows that as the water/ cement ration increase the flexural strength decreases....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
