dc.description.abstractCarbon dioxide is emitted during manufacturing processes of cement. It can be reduced to some extent either by limiting the use of cement or by replacing it with other eco-friendly material within certain limits. The present study was conducted to replace the Ordinary Portland Cement (OPC) with Corn Cob Ash (CCA) up to 20%. The workability, compressive strength, temperature effect and durability tests were conducted on concrete containing CCA. The use of CCA above 10% as a replacement of cement decreases the workability as well as the strength of concrete. Reduction in strength was small for the replacement level of 5% and 10%. The CCA as a replacement above 10% is not recommended as it affects the strength of concrete. The compressive strength of all mixes increases up to temperature of 300°C. Beyond this temperature, compressive strength decreases significantly for all the mixes. The serious deterioration has found at 600°C. Durability test was conducted at 3% and 5% concentration of sulphuric acid. Increase in acid concentration deteriorates the compressive strength of normal as well as CCA concrete. The increase in CCA content in concrete shows increase in its resistance to sulphuric acid at 3% concentration. The resistance of concrete to 5% H2SO4 solution decreases as CCA content increases in mixes. It can be seen that the curing age and addition of CCA content significantly affect the 28 days compressive strength at both normal and elevated temperature.en_US
