Anti-freezing anti-seepage self-compacting fine aggregate concrete for bridge reinforcement and preparation method and application of anti-freezing anti-seepage self-compacting fine aggregate concrete
The invention provides anti-freezing, anti-seepage and self-compacting fine aggregate concrete for bridge reinforcement and a preparation method and application of the anti-freezing, anti-seepage and self-compacting fine aggregate concrete. The concrete is prepared from the following raw materials in parts by weight: 390-410 parts of cement; 10 to 50 parts by weight of fly ash; 840 to 900 parts by weight of sand; 800 to 830 parts by weight of broken stone; 50 to 150 parts by weight of slag powder; 100 to 200 parts by weight of water; 10 to 20 parts by weight of an air-entraining type water reducing agent; and 15-25 parts by weight of an expanding agent. Compared with the prior art, the anti-freezing, anti-seepage and self-compacting fine aggregate concrete for bridge reinforcement provided by the invention adopts specific components with specific contents, realizes relatively good overall interaction, has freezing resistance, anti-permeability, expansibility and good cracking resistance, also has economical efficiency and generalizability, and is particularly suitable for bridge reinforcement in northern cold regions.
本发明提供了一种桥梁加固用抗冻抗渗自密实细石混凝土及其制备方法和应用；该混凝土由包括以下组分的原料制备而成：水泥390重量份～410重量份；粉煤灰10重量份～50重量份；砂840重量份～900重量份；碎石800重量份～830重量份；矿渣粉50重量份～150重量份；水100重量份～200重量份；引气型减水剂10重量份～20重量份；膨胀剂15重量份～25重量份。与现有技术相比，本发明提供的桥梁加固用抗冻抗渗自密实细石混凝土，采用特定含量的特定组分，实现整体较好的相互作用，产品具有抗冻性、抗渗性、扩展性，以及良好的抗开裂性，同时兼具经济性及可推广性，特别适用于北方寒区桥梁加固。
