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.
Experimental Raw Materials Cement: Chongqing ordinary Portland cement (42.5 R), which technical performance was accord with "common Portland cement" (GB175 -2007 ).
The mass ratio of water to cementitious materials was 0.39, The total cementitious material content was maintained constant(410kg/m3), and the replacement level of fly ash was 20%, sand percentage was 34%.

A wide range of materials can be used in SLS, such as nylon, polycarbonate, ABS, sand, wax and metal[3], but high price of materials is the bottleneck to constrain SLS application widely, so reducing the cost of materials has always been a research focus in this area.
Wood-Plastic Composites (WPC) is green biological materials, it has many advantages such as good mechanical properties, high hardness, anti-aging, dimensional stability, easy to color, with wood texture and also recycled, the most important advantage is low-cost[4].
It indicates that wax shows good bonding with WPC because both of Co-PES hot-melt adhesive powder and alkalized wood powder are non-polar materials.
