Abstract This study is to observe the ability and potential of used cooking oil as foaming agent admixture in lightweight foamed concrete. The intention is to utilize the waste materials derived from food industry which is known as used cooking oil. Due to this aim, several scientific observations and testings should be performed in order to observe the morphology of used cooking oil foam and used cooking oil foamed concrete. Other physical test has been performed to measure the viscosity and stability of used cooking oil foam. From the result, the morphology of used cooking oil foam was well developed and able to show their foam characteristic. Meanwhile, to compare the treated used cooking oil also having the viscosity value of about 88 cP which is proven to have good foam ability behaviour. Apparently the viscosity value of this used cooking oil showed that it had good stability compared with cooking oil foam.
1 Introduction Cooking oil is the main component in food production, especially for fried food. In Malaysia, the use of palm oil in cooking activities is quite popular. It is believed that, abundant supply of palm cooking oil is to induce the food industries and production [1]. Since there is an increase in food production, the use of palm oil is M.M.A. Hafiz (&) A.R. Mohd Ridzuan M.A. Fadzil J.

also increased. Due to this reason, the waste product also keeps increasing. The waste produced from the frying activities is so-called used cooking oil that is forever a portion of the waste that has to be discarded. In line with the reuse of used cooking oil, this waste product is familiarly involved with fuel engine combustion. One of this study’s intentions to utilize the waste of used cooking oil to become others new becomes green product is significant. To be particular, in this study, the aims are to observe the morphology characteristic of the foam produced by utilizing used cooking oil. The foam generally is thermodynamically unstable and usually influent with the drainage effect due to the gravity attraction [2]. Other than that, the coalescence makes the foam rupture and collapses to become liquid form. This situation makes the foam structure become less stable and easy to self-denature in foam structure. Another factor such as chemical added, the viscosity of the solution, mechanical forces, type blowing agents and type of surfactants also contribute to the stability and foamability of foam [3]. The constancy of the foam can be measured by cylindrical method and the viscosity is considered as major ingredie
