Investigating the effect of partial replacement of cement with eggshell powder in concrete production Department:Civil Engineering By: feeby12 Project ID: 2202 Rating: (3.0) votes: 19 Price:₦3000 Get the Complete MaterialAbstractConcrete is a structural material obtained from the mixture of cement, aggregates of fine and coarse, water and admixtures if necessary. Cement formally considered as inert of concrete production, it hardens and binds the aggregates and sand together. Finding a substitute for cement, the use of eggshell waste in replacement of cement also helps to minimize the waste in the environment. Fresh fowl’s eggshell was washed, dried, crushed and ground by mechanical grinding machine. The product generated after grinding was passed through sieve size of 75µm which is the range of particle size of cement (50µm-90µm). Particle size distribution was carried out on both fine and coarse aggregate in accordance with (BS 1377-2:1990), workability test was also carried out on the concrete. Specific gravity was carried out on cement, fine aggregate and cement. Concrete cubes were cast for each replacement (15%& 20%) with varying water cement ratio (W/C) of 0.4, 0.5 and 0.6. and they were cured for 7,14,28 and 56days respectively. Water absorption and consistency test were carried out on conventional and modified concrete (fowl eggshell). The result showed that 15% at 0.4w/c of replacement has the highest water absorption rate of 1.18% and 20% at 0.4w/c of replacement has the lowest water absorption rate of 0.41%. ...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»Determination of the causes, effects of environmental pollution and its possible control within Kwara and Osun state»Suitability of available laterite material in Ilorin East local government area for road construction»Model for prediction of rainfall intensity in Lagos
