UHPC超高性能混凝土

[發布時間:2021/12/7]


  UHPC超高性能混凝土是一種超高強、韌性、高耐久性的特種工程材料,在國防工程、海洋工程、核工業、特種保安和防護工程、以及市政工程領域有良好的應用前景。經試驗證明,其抗折強度是普通C50混凝土的3倍,縮變下降50%,經歷700次凍融循環后仍然完好無損,被稱為“不開裂”的混凝土。

 ●UHPC現已用于海洋石油平臺的鋼結構的外保護層,可大大提高水位變動區的支柱的使用壽命。

 ●UHPC的早期度發展快,后期度極高,用于補強和修補工程中可替代鋼材和昂貴的有機聚合物,既可保持混土體系的整體性,還可降低成本。

 ●UHPC強度高,抗沖擊性能好,可用于國防工程的防護結構,也可用于需要高承載力的特殊結構。

 ●UHPC的高密實性與良好的工作性能,使其與模板相接觸的表面具有很高的光潔度,外界的有害介質很難侵入到UHPC中去,而UHPC中的著色劑等組分也不易向外析出,利用這一特點可把UHPC用作建筑物的外裝飾材料。
