Article Title: Effect of the Use of Mound Soil as an Admixture on the Compressive Strength of Concrete
by O. U. Orie and B. U. Anyata

The paper examined some mechanical properties of mound soil concrete (MSC) to harness its structural property in the construction industry. Mound soil (MS), randomly selected from some habitats of a common tropical specie of termites from Iyeke-Ogba, Nigeria was investigated. The work applied the laboratory investigative methodology. Steel moulds measuring 150mm x 150mm x 150mm were used to cast cube samples from a standard 1:2:4 mix. Water to cement ratio (w/c) was kept constant at 0.55 and the content of mound soil was varied between 0 and 30%. The moulds were demoulded after 24 hours and the samples cured in a tank at 300C and were tested for 7, 14 and 28 days strength. The results showed that the control mix with 0% MS gave a compressive strength of 39.22 N/mm2 and slump of 65mm. Addition of 15% mound soil by weight of cement produced 47.78 N/mm2 with 24mm slump representing an increase of 21.83% in compressive strength and 36.92% improvement of workability. The paper concludes that MS can be used as an additive in structural concrete for high compressive strength and workability.
Keywords: concrete, admixtures, strength, workability and economy.
