Abstract: Durability of concrete has been defined as its ability to withstand deterioration after it has been exposed to the environment of its intended use. This work examined the performance of ternary Corncob Ash (CCA) and Anthill Soil (AHS) concrete in sodium sulfate (Na2SO4), magnesium sulfate (MgSO4) and combined Na2SO4 and MgSO4 solutions. Bar specimens for elongation tests and cubes for strength deterioration tests were cast using combined CCA and AHS at the 5% replacement, which was earlier on reported to have achieved the highest compressive strength, as well as at the 30% replacement. From the findings, it was concluded that at the 5% replacement, the ternary mix could be used with an advantage over 100% cement concrete in MgSO4 environments.
