ABSTRACT
The present study aims to determine the optimum dosage of oil palm shells in the soil to achieve better compressive strength of earthen bricks. The first part of this study is devoted to determining the characteristics of oil palm shells and soil. Then air-dried bricks are made by mixing soil, water and oil palm shells. The bricks made are kept in shade. Some of these bricks are regularly watered until the day of testing. The tests carried out on the bricks are the measurement of the compressive strength and the shrinkage on the 14th and 28th day of age. From this study it emerges that oil palm shells are a light and very resistant material that contains few fine elements. The earth used is predominantly clayey with a spread grain size and does not contain humus. Bricks compressive strength increases with in oil palm shells dosage and with age. The shrinkage decreases with oil palm shells rate. Watering improves bricks compressive strength and reduces their shrinkage.
Keywords: oil palm shells, compressive strength, clay soil, air-dried brick, watering.
