This study investigated the compressive strength of 50 x 50 x 50 mm termite mound cement and sand mortar made from mixes containing lime,. Mix ratios (1:4 and 1:6) and percentage replacements of cement with lime and termite mound in the order of 0%, 10%, 20%, 30%, 40%, and 50% were used. A total of 360 cubes were cast and cured in water. The specimens were also cured in 1% and 3% solution of tetraoxosulphate vi and trioxonitrate v acid for a period of 7, 14, 21, 28 and 56 days using water binder ratio of 0.65. Test results revealed that the compressive strength of the mortar cubes increases with age but decreases with increasing percentage replacement of cement with lime and termite mound when cured in water while the compressive strength decreases with age and decreases with increasing percentage replacement of cement with lime and termite mound for the specimens cured in acid. The compressive strength of the sample cured in tetraoxosulphate vi acid (H2SO4) is higher than that of trioxonitrate v acid (HNO3).
