Description
Foamed concrete is a low-density concrete that is highly air-entrained with more air per volume using materials such as sand, cement, and foam. Foamed concrete has the ability to be applied in various shapes as required. The statistical condition of foamed concrete, which is a free-flowing liquid, allows the foamed concrete to take place and shape accordingly. Epoxy resin is a type of thermoset polymer with a highly connected, crosslinked structure. Thermoset epoxy is known to contain high stiffness and strength. In this study, research was done by adding semiconductor epoxy resin waste as fine aggregate to produce non-loading bearings. The semiconductor epoxy resin waste was obtained from ST Microelectronics SDN BHD and was ground until the particle size was less than 0.6mm. The preparation of samples involved the grinding process of the Semiconductor Epoxy Mold Component Resin Waste and the mixing process of different percentages of RW at 0, 5, 10, 15, 20, 25, and 30% with the constant percentages of cement, quartz sand, water, and foam. Tests were carried out on the mix design, which involves compressive strength before and after elevated temperature (1000°C for 4 hours), tensile splitting strength, density and porosity. The results indicated that adding 10% semiconductor epoxy resin waste yielded the highest compressive strength of 9.88 MPa at 28 days and tensile splitting strength of 5.95 MPa, with the mixture achieving the targeted density of 900 kg/m3. This research demonstrates the viability of using semiconductor epoxy resin waste in foamed concrete, providing a sustainable solution for waste management in construction.
