Optimization of Cuttlefish Bone Towards Compressive Strength of Foam Concrete

Development and testing of other foam concrete materials, as well as the inclusion of a marine-based filler, cuttlefish bone powder, may be one of the most advanced products suitable for cementitious materials to be added in concrete to provide a sustainable environmentally friendly alternative solution on construction industry in Malaysia. Cuttlefish bone will have some advantages and benefits in foam concrete since it contains high amounts of calcium carbonate, which is believed can improve the concrete’s strength and encourage foam concrete to achieve an early strength. The objectives of this research is to determine the optimum percentage of cuttlefish bone additive towards increasing the strength properties of foam concrete. In this research, there were 42 foam concrete cube samples prepared, each group of samples containing different amounts of cuttlefish bone additive (1%, 2%, 3%, and 4%). All the samples were tested for compressive strength at 1, 3, and 7 days of age. According to the findings, an improvement in the foam concrete when the cuttlefish bone additive content from 1% to 4% added which result in the enhancement of the behavior of foam concrete. In addition, this research reveals that cuttlefish bone additive has better characteristics to normal OPC, making it an effective addition to concrete.
