The Evaluation of High Performance Fiber Reinforced Concrete as a Green Construction Material

Green concrete can be defined as the kind of construction material which is less energy and resources consuming, while at the same time it has less environment pollution in a broad sense. Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is one kind of this green concrete with outstanding working performance and the high material efficiency. UHPFRC is more and more widely used these years,which is manpower-efficient with superior flowability under maintained stability without any vibration. This paper provides a method to simulate the flowability of the UHPFRC using Computational Fluid Dynamics (CFD) method and also a discussion about the green degree of the concrete is made in the aspects of strength, aesthetics, durability,cost.
