Abstract:

This paper presents the results of an experimental work that was carried out to determine the effect of sugarcane bagasse ash (SCBA) on the durability of concrete to Sulphate attack when Sugarcane Bagasse ash is utilized as cement replacement material. Sugarcane bagasse ash (SCBA) is a fibrous waste product obtained from sugar mills as byproduct, which is obtained by burning of Sugarcane Bagasse at 700 to 800 degree Centigrade in sugar refining industry. The Bagasse Ash, then ground until the particles passing the 90 micron. Sugarcane Bagasse ash mainly contains aluminium ion, silica, iron & calcium oxides. The objective of this work is to study the influence of partial replacement of cement with sugarcane bagasse ash in concrete subjected to different curing environments. A study on salt resistance of concrete using Na2So4 Solution is observed. The variable factors considered in this study were concrete of grade M35 for a curing period of 28 days, 60 days and 90 days of the concrete specimens in 1%, 3%, 5% Na2Sosolution. Bagasse ash has been partially replaced in the ratio of 0%, 5%, 6%, 7%, 8%, 9%, and 10% by weight. The effect of Sodium Sulphate is determines by the loss of strength with respect to the conventional concrete which has been determined.
