5.0 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 properties of bricks
II. The lateritic soil samples have a specific gravity of 2.63, which classifies it as sand since it falls within the range of 2.6 - 2.7 for normal aggregate as specified by Lambe (1951).
III. The lateritic soil samples are sandy silt of high plasticity
IV. It was observed that the higher the density of the bricks, the greater their compressive strengths.
V. There was a reduction in the compressive strength of the sandcrete bricks produced with increased percentage replacement of the conventional fine aggregate with the lateritic soil.
VI. Bricks with laterite fine replacing the natural sand can satisfactory perform as masonry unit when the laterite fine content does not exceed 30%
RECOMMEDATION
This percentage replacement can be recommended to the brick moulding Industries along Asa dam Road Ilorin kwara state that strictly adhere to standard practice to incorporate lateritic soil not greater than 30% of the aggregate used into their sandcrete bricks production as this will reduce the production cost which will eventually reduce the cost of building production within the location.

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---
