Stabilised Compressed Earth Bricks Technology offers an alternative to the traditional Building practices that is relatively in-expensive, uses local resources and has been found to last long. The present rate of construction in developing countries as opined by Krishnaiah and Reddy, 2008 is generally sufficient to meet the need of only 10% of the net increase in population per year, due to the unavailability and soaring cost of conventional Building material. More efforts are being made to develop cheap, serviceable and energy efficient construction materials. Lime stabilization provides benefit to mortar and plaster, thereby enhancing workability and water retention and also react with CO2 to generate calcium carbonate.Earth as an ancient building material is constantly being improved and used in many different ways. It has been used locally to make bricks in many part of Nigeria without stabilization. Therefore, this research investigates the effects pulverized burnt brick on the strength characteristics of lime stabilised compressed earth bricks with a view to establishing the possibility of using PBB for improving the hydration of lime. The laterite used in this research was stabilized with lime and PBB by additive method. A total of 162 samples were produced and tested for compressive strength at 7, 14, 21, 28 and 56 days. And abrasion resistance, water absorption and sorptivity at 28 and 56 days respectively. From the chemical test, oxides of silicon, aluminium, iron and titanium had higher values of 39.357%, 28.357%, 17.045% and 12.402% respectively. It was observed from the results that samples containing 5% lime and 5% PBB stabilization had the highest average compressive strength of 1.35N/mm2 at 28 days and the lowest average compressive strength was obtained at 7 days for 5% lime and 15% PBB. Acontinuous increase in compressive strength of the bricks from 7 days to 28 days were observed. The highest compressive strength recorded for 0% was 1.10N/mm2 at 28 days and the lowest compressive strength recorded was 0.82N/mm2 at 7 days. Higher resistance to abrasion of 0.35% for 5% PBB at the age of 56 days and the lowest of 0.58% for 15% PBB at 28 days were recorded. The lowest absorption capacity of 1.88% at 56 days occurred for 5% PBB stabilization and the higher of 2.44% at 28days occurred 15% PBB stabilization. However, all un-stabilized samples partially dissolved in water. Sorptivity result shows that samples produced with 5% PBB stabilization were observed to have the higher resistance to capillary action of water at 28 and 56 days. It was observed that 15% PBB stabilization have the lowest resistance. The stabilization of laterite with Lime and PBB was found to be effective in enhancing strength and durability. Therefore, the use of Lime and Pulverized Burnt Bricks for stabilization of Lateritic Soil for the production of Compressed Earth Bricks is recommended in order to improve the quality of the bricks.Post Graduate Theses
