In concrete block production, a mould release agent is needed for lubrication during the process of detaching the moulded concrete from the mould. The mould release agent is called mould oil. Currently, concrete block manufacturers use a petroleum-based mould oil as the mould release agent. Frequent use of this oil causes health problems and has a negative environmental impact in the workplaces. Due to its toxicity, flammability (strong petrol odour) and ever-increasing price of the present commercial mould oil, the search for an alternative has been actively carried out. A new formulation of mould oil devired from palm olein has been discovered. It has optimum performance fulfilling every aspect of the specifications for a greener mould oil for concrete production besides ensuring that the production process and the finished concrete units comform to higher standards and more strigent conditions and regulations.
