Resumo:  This study was performed to assess termite mound inherent property as additive forimprovement of soil strength in Nigeria. The mound on the Rhodic Acrisol was sampled fromtop at 0 - 60 cm, 60 - 120 cm and 120 - 180 cm intervals through a vertical section. For theRhodic Acrisol, three samples were sampled from depth at 0 – 60 cm, 60 – 120 cm and 120 –180 cm intervals through a vertical section.Termite mound sample was mixed with the two  soil samples separately, that is, termite mound and clayey soil in one part and termite moundand laterite soil in another part. Twenty trials experiment were conducted on the soils duringcompact test for soil mix ranging from 0 to 100 % at interval of 5 %.  The optimum moisturecontent obtained from the compaction test was used to carry out compressive strength test.The Triaxial machine model HM -5020 was used for determination of the compressivestrength. The soil samples were examined in accordance with the American Public HealthAssociation. The data were analysed using descriptive statistics and one way ANOVA. Thefindings indicated that:  termite mound was classified as sandy clay loam soil while thelaterite soil was sandy loam; the termite mound has the highest maximum dry density andcompressive strength than other two soil samples; increases in termite mound ratio has issignificant increase in maximum dry density and little effect on optimum moisture content forboth soil samples; termite mound as an additive has much more effective in laterite soil thanclay soil in term of compressive strength and maximum dry density; the compressive strengthof the laterite almost doubled that of the clay soil at the same termite ratio. Termite isrecommended as an additive for laterite soil for building construction only.
