マイクロPPファイバー・コンクリートとは？
A clear definition that matches jobsite reality Micro PP fiber concrete is concrete that contains micro synthetic fibers made from polypropylene. A crew adds the fibers during mixing, and the crew spreads the fibers through the paste and aggregate. The word “micro” describes fiber size, and the word “PP” describes the polymer, and the word “concrete” describes the matrix that holds the fibers. ACI guidance defines microsynthetic fibers as fibers with diameters, or equivalent diameters, less than 0.3 mm, and the same ACI guide defines macrosynthetic fibers as larger than 0.3 mm. The ASTM D7508 specification uses a matching idea through linear density, and it describes micro polyolefin fiber as […]
