Waste-to-Green Concrete Composite
Cleaner production is a pressing concern of the 21st century. Waste materials resulting from different industrial processes requires proper management to ensure a cleaner environment. The use of recycled materials in new green concrete production is very attractive due to the low-cost related to the waste materials in addition to saving required space for landfill purposes and the development as well as improvement in the concrete properties.  We manage to study in details the use of waste carpet fibers and palm oil fuel ash in concrete. While the introduction of such fiber reduces the workability of the concrete mixture to as much as 80% depending on the amount of fibre, the composite manage to greatly reduce the water adsorption at longer curing period. The reduction is also partly due to the reduction of fibre pore, as much as 11%.

Reinforcement from the Nature
We did a study to investigate the structural behavior of reinforced concrete (RC) beams externally strengthened with various types of kenaf fiber reinforced polymer composite laminates with 50% fiber volume content. In general the strength of  all kenaf fibre composites gradually increased with increasing fibre volume fraction; the highest being kenaf/epoxy composites. The ultimate flexural strength and deflection improved by 40% and 20% respectively, providing significant reinforcement to the existing concrete beam.
