“…For clay, the test results showed that percentage of aggregate mixtures were almost similar to those obtained by C.M. Chan [15]. Apparently, clay composition did not match with that of the best soil composition required for producing CSEB.…”

Abstract. Compressed Stabilized Earth Brick (CSEB) is a sustainable material utilizing locally available soils mixed with stabilizers to increase its strength. Two main factors affecting the strength of prototype are its compressive strength and water absorption rate. In this study, the mix proportion ratio for producing CSEB prototypes from laterite soil and clay types was 1:10 (cement:soil). Three different compactions (i.e. 2000, 3000, and 4000 Psi) were applied to produce prototypes with dimension of 100×50×40 mm. The samples were tested at the ages of 7 and 28 days. For laterite soil CSEB, the optimum strength was achieved by the sample subjected to 2000 Psi compaction,withits compressive strength of 9.0 N/mm 2 and water absorption rate of 14.9%. For clay CSEBthe optimum strength observed was the sample subjected to 4000 Psicompaction, with the compressive strength of 5.8 N/mm 2 and water absorption rate of 17%. However, the compressive strength of clay CSEB is still below the level specified in the MS 76:1972, which is over 7 N/mm 2 for the load-bearing fired brick Class (1). This study also revealed that the increased in compression pressure would result in different strength performances for both CSEBs made from laterite soil and clay.

“…6a & b). According to the literature this can be considered suitable for construction (Houben and Guillaud 1994;Rigassi 1995;Jiménez Delgado and Guerrero 2007;Adeyemi and Wahab 2008;Oyediran and Okosun 2013;Giorgis et al 2014;Adeyemi et al 2015). The coarse particle (which corresponds to sand and gravel particle sizes, 0.06mm to 20mm) contents ranged between 50.3 -85.5% with the individual averages at 61.6% and 62.1% for the ADK and OS lateritic soils respectively.…”

Lateritic soils which have been described as highly weathered tropical or sub-tropical residual soils, were studied with an attempt to establish its suitability or otherwise as sustainable material in building bricks and housing development that will meet the present challenge of sustaining the environment without costing too much and maintaining a high standard of strength, durability and aesthetics. Index properties of the tested lateritic soils revealed them as mostly well-graded, comprising both cohesive (silt and clay) and cohesionless (sand and gravel) soil fraction. The geotechnical analyses on the studied lateritic soil revealed a strong compressive strength with a relatively sound dry density which could guarantee a good durability in resulting bricks made from these soil materials.Further test on the strength and durability of the compressed earth bricks (CEBs) made from these lateritic soils revealed a brick with compressive strength ranging between 6.33 and 15.57 MPa which are considered to be good strength coupled with its sound durability strength established over a period more than one year under a complete cycle of weather and seasonal conditions.In conclusion, lateritic soils from the study area were found to be suitable as materials for bricks (CEB) with good compressive and durability strength which qualifies them sustainable and cost effective materials for lowcost housing development.
