Abstract: This research investigated the influence of introducing binary and ternary blends of binding materials on the properties of concrete. Calcium hydroxide is one of the hydration products of cement which creates a weak link in concrete, thereby affecting the durability properties of the concrete. Supplementary Cementitious Materials have been known to react with the deleterious calcium hydroxide to create additional beneficial Calcium Silicate Hydrate, which is the main cementing component in concrete. Supplementary Cementitious Materials reduce the quantity of lime and increase the quantity of the Calcium Silicate Hydrate. The cementing quality is enhanced if a good pozzolanic material is blended in suitable quantity with Portland cement. A standard mix proportion of 1:2:4 and water cement ratio of 0.65 was adopted for all the concrete mixes. A total of 36 cubes of 150mm x 150mm x 150mm were cast with 20% OPC/AHA and 10% OPC/CCA binary blended cement concrete, 36 with OPC/AHA/CCA ternary blended cement concrete at percentage OPC replacement of 5%, 10%, and 15% were crushed to obtain the compressive strengths at 7, 21, 28, and 56 days of curing, 18 beams were also produced and tested for flexural strength. The 7 – 21 day compressive strength of 20% OPC/AHA binary blended concrete were found to be much higher than the control values; the compressive strength for 28 -56 days were slightly lower than the control values. The 10% OPC/CCA attained the highest compressive strength of 24.50N/mm2 at 56 days of curing. The 56 day compressive strengths obtained from the ternary blended cement concrete with equal quantities of AHA and CCA were 25.60 N/mm2 for 5% replacement, 19.50 N/mm2 for 10% replacement, 17.00 N/mm2 for 15% replacement while the value for the control was 26.80 N/mm2.
