Evaluation of the Strength Properties of Soil Bricks Produced with Processed African Locust Bean Waste water as Stabiliser
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 1
Abstract
A newly proposed concept of soil bricks as masonry units for low-cost environmentally friendly construction is proposed using agro-based waste water obtained from the processing of the African locust bean into local food condiments. Laboratory test system was designed to perform strength and durability test on four types of soil brick mixed with African locust bean waste water (ALBWW) as replacement of portable water and also as soil stabiliser for bricks production. Tests were conducted on strength and durability properties of the specimens. There was an increase of 66% over unstabilised specimens when the soil was fully mixed with ALBWW. The density of the bricks increased from 2120kg/m3 for the soil bricks without ALBWW to 2167kg/m3 when the soil was mixed with ALBWW. The resistance to wear for bricks increased steadily from 6.45cm2 /g for bricks without ALBWW as stabilisation to 9.45cm2 /g for bricks with ALBWW. The presence of ALBWW reduced the amount of water absorbed by the bricks. The study concluded that ALBWW which is an environmental nuisance can be used to replace portable water and also as stabiliser for masonry units in construction. This then implies that effective utilization of ALBWW as soil stabiliser would reduce the cost of relative durable houses for the rural and peri-urban areas in Northern part of Ghana where locust beans are prevalent.
