Title:        Developing an Economized Normal Strength Concrete by Incorporating Bagasse Ash as Partial Replacement of Cement
Authors:  Muhammad Omer Tariq, Usman Amjad, Syed Azmat Ali Shah
Abstract:  Pakistan produces approximately 52 Million tons of Sugar cane annually and most of it is used for production of Sugar. The industrial waste of Sugar cane, known as bagasse, is used throughout the world as fuel for power generation in the same mills from where it is obtained. The burning gives ash containing high proportion of matters that are unburned silica and alumina as main components, which have the characteristics to react with free lime made available as the by-product of cement hydration. This research study is carried out to evaluate the feasibility of use of bagasse ash, in production of concrete, as a partial cement replacement. The most important variables of this research study are the proportion of bagasse ash and dosage of superplastisizer.The parameters which remained constant are the quantity of cementitious material equal to 430 Kg/m3 and water to binding material ratio equal to 0.55. Test results revealed that the mixes associated with bagasse ash,showed slightly lower compressive strength than Control Mix (CM). However, it showed better resistance against water absorption as compared to CM. The concrete produced using bagasse ash as partial replacementof cement has exhibited excellent properties as construction material. Government of Pakistan has allowed sugar mills to generate electricity through bagasse, this will produce large amount of bagasse ash as industrialwaste. The successful bagasse ash use as a partial cement substitute would minimize the construction cost and will also significantly help to lessen the greenhouse gases.
