Interpretation of Grain Size Analysis
The graphical representation of the results of the grain size analysis (Fig. ) of soil sample gave an indication that sand predominates with percentage composition of 43%, of sand, 30% of silt, clay of 25%, and gravel making up 2% and thus is silty sand,
The percentage compositions of the grain sizes sample shows that the grain sizes are not evenly distributed and this suggests a poor grading. The lateritic soil sample are classified as group symbol SM according to the Unified Soil Classification System. On the engineering use chart, the soils have a group symbol of SM. According to the Engineering Use Chart these soils are impervious, have good to fair shearing strength when it are compacted and saturated, low compressibility when compacted and saturated, and have good workability as construction materials which can resist erosion. The samples according to the aforementioned results suggest that it can be used in the construction of Earth fill dams.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 Introduction Lateritic soils are formed in hot, wet tropical regions with an annual rainfall between 750 to 300mm, (usually in areas with a significant dry season) on a variety of different types of rock with high iron content. The location on the earth, that characterize these conditions fall between latitude 35oS and 35oN (Person, 1970).Laterisation is the removal of silicon through hydrolysis and oxidation that result in the formation of laterite and lateritic soil ...

CHAPTER TWO - [ Total Page(s): 9 ]CHAPTER TWO2.0 Literature ReviewLaterite is often used to describe the clinkered siliconized clay material. According to Amu et.al. (2011), it could be described as materials with no reasonable constants properties while Villain Cocinaet et.al. (2003), described it as a red friable clay surface, a very hard homogenous vesicular massive clinker-like material with a framework of red hydrated ferric oxides of vesicular infill of soft aluminum oxides of yellowish color. Villain Cocinaet et.al ... Continue reading---
CHAPTER THREE - [ Total Page(s): 7 ]ProcedureAbout 200g of soil sample was passed thoroughly with distilled water to form a uniform paste. A portion of the paste was placed in a brass trough bar (linear shrinkage trough device). The surface of sample was leveled and smoothened off to the brass of the trough bar and the trough was then placed in an oven for 24 hours at temperature of about 105°C. The initial length of the trough bar filled with the soil sample was taken. After 24 hours, the trough bar was brought out of the oven ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSIONS, REFERENCE AND RECOMMENDATION. 5.1 Conclusion. Tests have been conducted to evaluate the suitability of lateritic soils along Asa dam area Ilorin kwara state and its effect on the strength of sandcrete bricks when used to replace the conventional fine aggregate, the following conclusions can be drawn from the analysis of the results: I. The use of lateritic fine as a partial replacement has a significant influence on the engineering pro ... Continue reading---
