CHAPTER FOUR
4.0 RESULT AND DISCUSSION
4.1 Brick Moulding Observation
After the trial mix as described in bathing and mixing, to determine the quantity of water needed to mix a batch, it was observed that the quantity of water with same volume as the trial mix was only possible to produce the control mix and the ten percent (10%) lateritic soil replacement and more volume of water was needed to produce higher replacements of lateritic soil. If the water was not increased, the fresh sandcrete brick will not come out of the mould and if forced out by vibrating while removing from the mould, the fresh sandcrete brick will shatter out of the mould thereby not maintaining the mould-shape. The higher the lateritic soil replacements, more water content were needed to effectively mould them to a perfect sandcrete bricks shape. But despite the increase in water content for effective moulding, perfect bricks can’t still be moulded beyond thirty percent (30%) replacement with the lateritic soil and the thirty percent (30%) replacement has to be done several times before finally getting a perfect mould after the mould was heavily lubricated with dies

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---

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---
