It was achieved through sampling and testing of the weak lateritic soil itself and by the addition of different proportions of maize husk ash. Natural moisture content and specific gravity of the material were obtained as 8.41% and 2.73 respectively. Atterberg Limits revealed the plastic limit the soil is non-plastic. The liquid limit also increased from 15.77, 18, 38, 30 and 42 at 0%, 2%, 4%, 6% and 8% respectively. The compaction shows that the optimum moisture content (OMC) was observed to have decreased from 10.03% at 0% to 8.69% at 2%, 7.37% at 4%, 9.20% at 6% and increased to 11.89% at 8%. The maximum dry density (MDD) increased from 2%, 4%, 6% and decreased at 8% with maize husk ash content. This increase in MDD agrees with a report relating that cementitious stabilizers generally increase the maximum dry density of soils at optimal amount between 2– 8%. The CBR shows that at 0% the value was 17.26% having gained an increased value from 2% to 6% as 18.13%, 23.29% and 19.10% which is very significant but 16.72% at 8% hence proved irrelevant. As such the stabilized weak soil can be used as a sub-base and in low strength required soil for fill, etc. as specified by the Federal Ministry of Works Specification....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
