To Study the Partial Replacement of Cement with Sugarcane Bagasse and Wood Ash with Addition of Aramid Fiber

Abstract

Abstract: Concrete is widely considered for its strength to withstand heavy loads and that‟s why this matrix is used for construction purposes. The growth in population has placed an enormous need for more and more infrastructure and it keeps growing. The outcome of this demand is the increase in production of cement. Massive amount of waste materials and byproducts are produced by manufacturing enterprises such as silica fumes, wood ash, and mineral slag and so on. As a result, waste management has become a huge problem for our environment. There are several minerals in wood ash, which can be extracted for further use. A big ingradient calcium carbonate, which is 25% or even 45% (depending on feedstock and burining condition). Less than 10 percent is potash and less than 1 percent is phosphate; there are some elements of iron, manganese, zinc, copper and some metal parts. These numbers however, vary as combustion temperature is an important element for the determination of wood ash. Many of these are in the form of oxides, mainly. If we mix the ashes to water the insoluble silica and calcium carbonate will settle to bottom and sodim salt and soluble potassium will dissolve. Sugarcane is commonly used to produce sugar and ethanol. After sugar juice is extracted from sugarcane, sugarcane bagasse is produced, which is about 50% of the sugarcane level. Bagasse is widely used as a fuel in combining steam production and power generation. In this process, sugarcane ash (SCBA) remains the last waste in the sugar production chain.. However, SCBA is generally disposed of in landfills in India The experimental investigations are carried out for compressive strength, split and flexural strength for curing period of 7, 14 and 28 days. The experimental results show that the for a combined replacement percentage of 8&8%, which includes 8% SCBA and 8% WOOD ASH with addition of aramid fiber 1.2% the values of compressive strength, flexural strength and split tensile strength were higher when compared to other replacement percentages The result shows that concrete workability is fine and within limits after replacing cement with SCBA, WOOD ASH with addition of aramid fiber. However, workability gets reduced at higher replacement of materials. The strength parameters such as compressive strength, flexural strength, and split tensile strength also increase and show an optimum value at 8&8% cement replacement and 1.2% Addition of aramid fibers respectively.
