Design and Construction Control of C60 Polypropylene Fiber Concrete Mix Ratio
Combined with A0 block concrete of Pier 521 construction features of Xuhong River Bridge,the design and construction control of C60 polypropylene fiber concrete mix ratio was studied in this paper.The results show that:not only does the concrete strength meet the design requirements,but also the bulk concrete does not appear bubbles,watermarks,sand lines,color differences,cracks and other appearance quality problems and passes the concrete quality test of A0 block of pier 521 at one time.The crack resistance,abrasion resistance,fatigue resistance and long term durability of high grade concrete were significantly improved by the incorporation of polypropylene fibers..
