Abstract

This research project talks about the design and fabrication of composite water tank added with fly ash for residential unit. Fly ash is a by- product of a coal combustion power plant which deposited on landfills which harm for the environment. This research is intended to add fly ash into fiberglass to reduce the amount of the waste. In order to fulfil the objective, effect of the fly ash on fiberglass is tested and prototype water tank was created using a mould. The sample was created using a hand-layout method for a composition of 0%, 5%, 10% and 15% of fly ash by creating a sheet a length of 550 mm and a width of 340 mm. The specimen was cut using CNC laser cutting machine after creating the design of the samples on Solidworks Software. The sample is tested for Tensile Test, Flexural Test and Water Absorption Test. Result of the Tensile Test indicate that composition 0% fly ash has the highest tensile stress about 163.597 MPa compared 5%, 10% and 15% of fly ash. Result of Flexural Test shows that composition of 0% and 5% of fly ash has almost same flexural stress 292.661 MPa and 290.088 MPa while composition of 10% and 15% of fly ash has 267.923 MPa and 266.056 MPa. Result of water absorption test shows that composition of 10% fly ash has the lowest water absorption percentage. The result of the test is analysed and choose which is the best percentage of fly ash to add into fiberglass. A prototype tank was fabricated with composition of 0% fly ash and 10% fly ash and a comparison was made on water absorption rate on both tanks.
