Modelling and simulation of structural performance of beam using high volume bottom ash as aggregates replacement

Coal fired power plants produce an abundance of by-products in the form of bottom ash and fly ash that can be categorized as waste, which threatens the environment as well as the health and safety of human life. Hence, innovative and sustainable solutions may be required to reduce the amount of wast...

Civil engineering (General) Coal fired power plants produce an abundance of by-products in the form of bottom ash and fly ash that can be categorized as waste, which threatens the environment as well as the health and safety of human life. Hence, innovative and sustainable solutions may be required to reduce the amount of waste, such as reusing the waste as construction materials for infrastructure development. In this study, Coal Bottom Ash (CBA) was substituted as an aggregate replacement in concrete with six different combination arrangements, ranging from 50% to 100% fine and coarse aggregate replacement with a constant 20% fly ash (FA) addition to the cement quantity. The experiments were conducted to determine the mechanical properties of concrete and performance as well as behaviour of reinforced concrete (RC) beams under a four-point bending load test. During the test, the deflection and applied load were recorded, and the cracking pattern was observed and marked. The results showed that concrete and RC beams with 100% coarse coal bottom ash (CCBA) and 100% fine coal bottom ash (FCBA) performed better in terms of mechanical properties, cracking pattern and load deflection results compared with the control concrete mix in 28 days of curing age. Furthermore, finite element analysis (FEA) models of RC beams were developed using ABAQUS software to predict the behaviour and performance of the tested beams. The accuracy of the FE models was validated using the experimental load-deflection responses and cracking patterns. In comparing analysis and experimental data, the results showed that FEA successfully predicted the cracking pattern and load-deflection curve of beams. The FEA results indicated that the beam with 100% CCBA 100% FCBA shows the highest data at 88 kN with maximum deflection 18.5 mm. The ultimate load obtained in ABAQUS for all RC beams were in a 10% range difference with the experimental results. This study concludes that RC beams incorporated with CBA as fine and coarse aggregates result in the highest strength compared to others and the FEA results indicate that the simulation data are in line with the experiment data. 2023-02 Thesis http://umpir.ump.edu.my/id/eprint/39609/ http://umpir.ump.edu.my/id/eprint/39609/1/ir.Modelling%20and%20simulation%20of%20structural%20performance%20of%20beam%20using%20high%20volume%20bottom%20ash%20as%20aggregates%20replacement.pdf pdf en public masters Universiti Malaysia Pahang Faculty of Civil Engineering Technology Nur Farhayu, Ariffin
