超薄混凝土抗裂性能研究

在超薄混凝土罩面中,由于罩面层偏薄导致混凝土表面开裂时有发生,应用纤维阻裂的原理,通过钢纤维和聚丙烯脂纤维的对比研究,提出用聚丙烯脂纤维能更好解决这一难题的结论,可为超薄混凝土的推广应用提供技术支撑.

Study on Anti-Crack Technical of Ultra-Thin Whitetopping

The surface of concrete cracks are taken place at times in the ultra-thin whitetopping overlay because the overlay is very thin. Through a thoroughly comparative study on steel fiber and polypropylene resin fibers, the researcher proposes polypropylene resin fiber is better than steel fiber to prevent from cracking. The principle that fiber can prevent from cracking has provided a technical support for the use of ultra-thin whitetopping.
