Behaviour of normal concrete with Sugarcane Bagasse Ash (ScBA) as partial cement replacement

Abstract

Concrete has been known to the world to be one of the most crucial components of a developing country but there some downsides to the environment in making the concrete. Mixing concrete needs water, fine aggregates, coarse aggregates, and cements as the main component. Cement is the main cause of the disadvantages of normal concrete mixing because in cement production, it will emit a lot of carbon dioxide to the environment. The emission of carbon dioxide to the atmosphere is proven as one of the main problems that cause air pollution and greenhouse effect. Furthermore, in an agricultural dependent country like Malaysia, the agricultural waste had been concerning to the public whereby the Sugarcane Bagasse (ScB) is one of the agricultural wastes. Sugarcane Bagasse can be useful towards the civil engineering communities where the Sugarcane Bagasse can turn into ash by burning and grinding the Sugarcane Bagasse residual and turn into Sugarcane Bagasse Ash (ScBA). The Sugarcane Bagasse Ash (ScBA) need to grind to make the particles of the ash to be cement-like of the particle size. Therefore, the purpose of the Sugarcane Bagasse Ash (ScBA) in this research is to replace some percentage of the cement to minimize the production of cements. So, the objective of the research is to identify the optimum percentage of Sugarcane Bagasse Ash that can produce maximum value of compressive strength of concrete when it is being replace by Sugarcane Bagasse Ash (ScBA). The percentage of Sugarcane Bagasse Ash (ScBA) that will replace the percentage of cements is 0%, 4%, 8%, and 12%. Based on the results obtained the compressive strength of the concrete mix with 4% of Sugarcane Bagasse Ash (ScBA) is higher compared to the control sample which is 45.60MPa where the control sample only have 38.83MPa. In conclusion, by using the Sugarcane Bagasse Ash (ScBA) it is proven that with the agricultural waste, it can be useful to the not only civil engineering communities but also to the world with the invention of using the Sugarcane Bagasse Ash (ScBA) as a replacement for cements where it can reduce the carbon dioxide emissions and the concern towards agricultural waste.
