Concrete is to be placed into prepared formwork of 4m in height to construct walls for an industrial building at a remote location. The concrete will require a retarding admixture to be added to facilitate the transport and handling of the concrete into the formwork. You are informed that the maximum lateral design pressure the formwork can withstand is 80kPa. You are to assume that the concrete temperature is 27°C and the concrete density is 2,400 kg/m³. (4 marks) Using the above information and the data specific to your ZID listed in Table 2, determine what cementitious material should be used to construct the walls.
