Chloride ion erosion-resistant sea sand concrete with high fiber content and preparation method of chloride ion erosion-resistant sea sand concrete
The invention relates to chloride ion erosion resistant sea sand concrete with high fiber content and a preparation method of the chloride ion erosion resistant sea sand concrete. The chloride ion erosion resistant sea sand concrete comprises the following components in parts by weight: 200-250 parts of cement; 160 to 180 parts of water; 80 to 100 parts of granulated blast furnace slag powder; 70 to 80 parts of fly ash; 700 to 800 parts of sea sand; 900 to 1100 parts of coarse aggregate; 3-4 parts of an efficient water reducing agent; the volume fraction of the steel fibers is 1%-5%, and the volume fraction of the inorganic fibers is 0.3%; and the volume fraction of the organic fibers is 0.5%. After the organic fibers and the inorganic fibers with high mixing amount are intertwined, the inorganic fibers with high elastic modulus are used as a framework to form a blocking layer with partial rigidity, gravity settling of the steel fibers is prevented, the toughening effect and the later-stage structural stability of the steel fibers are improved, and the chloride ion penetration resistance and the mechanical property of the sea sand concrete are effectively improved.
本发明涉及一种高纤维掺量耐氯离子侵蚀海砂混凝土及其制备方法，包括如下重量份数的各组分：水泥200～250份；水160～180份；粒化高炉矿渣粉80～100份；粉煤灰70～80份；海砂700～800份；粗骨料900～1100份；高效减水剂3～4份；化学降粘剂0.1份，钢纤维体积率1％～5％，无机纤维体积率0.3％；有机纤维体积率0.5％。高掺量的有机纤维与无机纤维互相缠绕后，以弹性模量较高的无机纤维为骨架，形成带部分刚性的阻断层，阻止钢纤维重力沉降，提高了钢纤维的增韧效果与后期结构稳定性，有效提升了海砂混凝土的抗氯离子渗透性能与力学性能。
