Abstract Fiber-reinforced polymer (FRP) bars are gaining popularity as an alternative to steel reinforcement due to their advantages such as corrosion resistance and high strength-to-weight ratio. However, FRP has a lower modulus of elasticity compared to steel. Therefore, special attention is required in structural design to address deflection related issues and ensure ductile failure. This research explores the use of machine learning algorithms such as gene expression programming (GEP) to develop a simple and effective equation for predicting the elastic modulus of hybrid fiber-reinforced polymer (HFPR) bars. A comprehensive database of 125 experimental results of HFPR… More >

Abstract In the Fibre Metal Laminate (FML), Carbon Reinforced Aluminium laminate (CARALL), aluminium is placed next to carbon fibres. The potential difference between the aluminium and carbon is larger, leads to galvanic corrosion, which tries to bring down the durability of the FML. To bring down the effect of corrosion, a material layer is introduced between fibres and aluminium so as to separate them thus lowering the possibility of occurrence of corrosion. Another approach is to coat the surfaces of aluminium with different proportions of aluminium oxide nano particles prior to fabrication of the FML. For More >

Abstract As the landfill leachate has strong pollution on the underground water, surface water and soil. This paper develops the formula of impervious slurry with low permeability, good durability, strong adsorption and retardant based on the bentonite which is modified by polyvinyl alcohol. Through the simulation experiment, the optimum formula of polyvinyl alcohol is 0.2%. Its osmotic coefficient for 28 days is 0.53×10-8~1.86×10-8 cm/s and compressive strength is 0.5~1.5 MPa as well. This paper study on the retardant rule of the consolidation of slurry against the pollution in the leachate by self-made percolation instrument. The experiment More >
