Orthogonal Experimental Study on Frost Resistance of Polypropylene Fiber Concrete
The orthogonal test method is used to research effect of the factors on the concrete’s frost resistance performance. The factors include volume fraction of fibers, water-binder ratio, fly ash and water-reducing agent. The results show that the polypropylene fiber influences on the mass loss of concrete noticeably, which can improve the frost resistance of concrete. The match ratio of the concrete is optimized. Finally the best match ratio is found out, which meets strength and frost resistance of concrete.
