1.1 Background of the Study
Different types of stabilizers have been used in different parts of the world to enhance the engineering properties of laterite (Moh, 1962). The most common ones are cement, lime and bitumen and the choice of a particular stabilizer depends on the soil type and degree of effectiveness of the stabilizers (Rahaman, 1968). Mustapha (2006) defined soil stabilization as the treatment of soils to enable their strength and durability to be improved such that they become totally suitable for construction beyond their classification if left untreated. Stabilization as viewed by Afjman (1994) is the process of blending and mixing materials with a soil to improve certain properties of the soil. Afjman (1994) further explained that stabilization process may include the blending of soils to achieve a desired gradation or the mixing of commercially available additives that may alter the gradation, texture or plasticity or act as a binder for cementation of the soil. Stabilization can be used to function as mechanical stabilization, additive stabilization or modification.
Mechanical stabilization is accomplished by mixing or blending soils of two or more gradations to obtain a material meeting the required specification. The soil blending may take place at the construction site, a central plant or a borrow area. Additive stabilization is achieved by the addition of proper percentages of cement, lime, fly-ash, bitumen or combination of these materials to the soil. The selection of the type and determination of the percentage of additive to be used is dependent upon the soil classification and the degree of improvement in the soil quality desired.

ABSRACT - [ Total Page(s): 1 ]Clay soils have been used locally in Sokoto to make bricks without stabilizing the soil. The bricks usually experience structural failure such as cracking and seasonal swelling when used for the construction of wall. Collapsing of wall also occurs in the area where non-stabilized bricks are used for wall construction. This research aims to assess the effect of lime-stabilization on strength of bricks made with Sokoto Red Clay Soils with a view to determining the physical properties of the soil a ...
