Sugarcane Bagasse is the fibrous residue leftover when sugarcane is squeezed for its juice. Bagasse ash is obtained by subjecting Bagasse to calcinations using furnace. This work is aimed tat using Bagasse Ash as a replacement in the production of concrete.
The bagassewas collected from dumped in a marketin Kano and thereafter sun-drie to eliminate any trace of moisture. It was then taken to the blast furnace for calcinations(controlled burning) at a temperature of 1250OC for 25minutes.The ash was then weighed and sieved with a 90μm standard sieve and the quantity retained on the sieve (black carbon) was weighed and discarded. The ash collected was investigated and its chemical compositions were obtained. Normal Consistency and Setting time for Cement and bagasse ash were determined. The concrete was batched using mix ratio 1:2:4 and the cement was replaced in varying percentages of 5%, 10%, 15%, 20% and 25% using Bagasse ash.Thereafter, the concrete was cured for 7, 14, 21, and 28days and its properties both in fresh and harden state were determined.
The result for Normal consistency of cement was achieved at 35% of water cement ratio (140ml of water added) which is equal to 34mm penetration.While Normal consistency for Bagasse ash was achieved at 33% of water Sugarcane Bagasse Ash (SCBA )ratio (132mls of water added) which is equal to 35mm penetration. Hence, the cement and bagasse ash are satisfactory for normal consistency of 34 to 35% range of specification.The Slump of the concrete shows a slight reduction as the bagasse ash content increases. Also, the results of the compressive strength of concrete at 20% replacement has highest compressive strength of 19.94N/mm2 at 28 days.
