Utilization of used cooking oil as foaming agent in lightweight foamed concrete. / Mohd Hafiz Md Ali

The utilization of used cooking oil (UCO) from waste materials to be a foaming agent (FA) for foamed concrete production. Purposely this study is to promote the use of waste materials become a useful product. As to achieve the target, several aims to be focus and the main objective is to formulate UCO become FA for foamed concrete. After several processes, UCO now available to work as FA and so called formulated used cooking oil foam (FUSCOF). To ensure the integrity of FUSCOF begin a foaming agent, several testing were conducted such as chemical and physical characterization, stability, morphology and mechanical properties. As a result, FUSCOF determined as most stable foam and self-rising foam while comparing with commercial and prove has better foaming agent properties. One of the significance findings is that the formulation of UCO (Used Cooking Oil) to become a forming agent (FA) which used for foamed concrete production which known as FUSCOF. By using chemical instrumentation such as GC-MS and FTIR, the quantitative analysis of UCO contain ethanol, eicosadine, oxirane and Octadec-9-enoic acid. Furthermore, the highest compressive strength attain by FUSCOF when the percentage of foaming agent added to the concrete mixture of 10%. The compressive strength gradually increased starting from 3,7, 14, 28 and 56 days of curing. Therefore , UCO can be used as well panel, floor slabs and roof.
