High-durability concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-durability concrete as well as a preparation method and application thereof. The high-durability concrete is prepared from the following raw materials in parts by mass: 50 to 70 parts of ordinary Portland cement, 15 to 20 parts of admixture, 330 to 450 parts of aggregate, 2.3 to 5 parts of admixture, 20 to 30 parts of super absorbent resin, 5 to 8 parts of titanium dioxide whisker and 40 to 50 parts of water, wherein the ordinary Portland cement is selected from cement of P.O52.5 or above, and the chloride ion content is less than 0.03%; the admixture is at least one of slag, fly ash and silica fume; the total mass of the ordinary Portland cement and the super absorbent resin accounts for 12-20% of the total mass of the raw materials; and the water cement ratio is controlled in a range of 0.36 to 0.6. The high-durability concrete can be used for a main body structure of a cross-sea bridge, and has the advantage of high chlorine salt erosion resistance.
本发明涉及混凝土领域，具体公开了一种高耐久性混凝土及其制备方法及用途。高耐久性混凝土包括如下以质量份数计的原料：50‑70份普通硅酸盐水泥、15‑20份掺和料、330‑450份集料、2.3‑5份外加剂、20‑30份高吸水树脂、5‑8份二氧化钛晶须和40‑50份水；其中，普通硅酸盐水泥选用P.O52.5及以上水泥，且氯离子含量＜0.03%；掺和料为矿渣、粉煤灰和硅灰中的至少一种；且所述普通硅酸盐水泥和所述高吸水树脂的总质量占原料总质量的12‑20%；所述水灰比控制在0.36‑0.6的范围内。本申请的高耐久性混凝土可用于跨海大桥的主体结构，其具有抗氯盐侵蚀能力强的优点。
