Study on Performance of High-performance Concrete made with Fly ash and Polypropylene Fiber Lanfang Zhang 1,a，Ruiyan Wang 1,b 1School of Civil Engineering & Architecture; Chongqing Jiaotong University; Chongqing 400074;China, ayyzhanglf@163.com, btjhlaraw@yahoo.com.cn Keywords: fly ash, polypropylene fiber, concrete Abstract.
Introduction Concrete is a kind of building material used widely in civil engineering, which have some merits ,such as low cost, extensive raw materials, simple process ,easy molding etc., but at same time, concrete is also a kind of brittle material with some faults , for example ,the ratio of tensile-compressive strength is low, it has non-uniformity, it is easy to crack, and impact resistance toughness is poor, so it is often added a certain amount of fiber to improve the performance of concrete in engineering. polypropylene fiber is a kind of fiber which the chemical properties are stable, acid and alkali resistance is strong, and can’t react with cement, mineral admixture, water and additive etc., This research will use fly ash and polypropylene fiber to improve the brittle, impact resistance and other performance of concrete, so as to meet needs of large-scale important engineering in current and future.
