摘要：This study aimed at investigating the properties of sorghum husk Ash blended cement laterized concrete cured in water. The research work focused on the determination of chemical composition of sorghum husk ash (SHA), the specific gravity of SHA and geotechnical properties of Laterite used in preparing laterized concrete with a view to providing vital information regarding the physical properties as well as the behaviour of concrete obtained thereof. A total of 81 cubes were moulded, nine (9) cubes each varied SHA laterized concrete groups of 0%, 10% and 20% corresponding to 7, 14 and 28days hydration period at 0%, 10% and 20% cement admixture. Of The 81 cubes, 9 cubes at 0% 10% and 20% SHA the specific gravity of SHA was found to be 2.1, the bulk density is 1564kg/m3 and essential pozzolanic oxides (SiO2 + Al2O3 + FeO3) is 72.39, loss of ignition (Lol) is 0.1%. The specific gravity of Laterite was found to be 2.69, the bulk density value is 1145kg/m3, liquid limit, plastic limit and plastic index were 34.15%, 50.0% and 18.0% respectively. The maximum compressive strength at 28days was found to vary from 18.45 N/mm2 at 7 days, 25.66 N/mm2 at 14 days and 26.03 N/mm2 at 28 days
