Abstract
Investigations were conducted on the bricks without stabilisation and with
chemical stabilisation by adding 2%, 4%,6%, and 8% of shea butter oil
processing residue “shea butter residue” weight of soil and its effect on the dry
density, compressive strengths, abrasive resistance and water absorption
coefficients at different moistures contents were analysed after 28-days of air
curing. A local Kaleo-Wa, Ghana soil was chemically stabilised by shea
butter residue. A better compressive strength was obtained with shea butter
residue stabilisation, and best values were obtained at shea butter residue
content of 4%. Optimal water content was sought to get higher strength and
higher durability. Abrasive resistance increased with increase in the shea
butter residue content. This then implied that the shea butter residue in the
brick helped to reduce wear of the bricks from external factors. shea butter
residue stabilisation reduced substantially the absorptivity from 3.06% for 0%
shea butter residue content to 2.79%, 2.53%, 2.36% and 2.22% when the shea
butter residue content was 2%, 4%, 6% and 8% respectively. shea butter
residue content in the blocks thus resulted in lower migration of water into the
bricks (i e. lower permeability). Bricks stabilised with shea butter residue are
largely dependent on local readily available raw materials and labour and are
appropriate building materials which should be a viable alternative to the more
expensive building materials such as shea butter residuet stabilised soil blocks
currently used in Ghana for walling of low cost housing.
