Magnesite concrete with high sulfate attack resistance and preparation method of magnesite concrete
The invention relates to the field of magnesite concrete, and particularly discloses magnesite concrete with high sulfate attack resistance and a preparation method thereof. The magnesite concrete is prepared from the following components in parts by weight: 360 to 430 parts of cement, 1128.5 to 1146.6 parts of coarse aggregate, 663 to 689 parts of fine aggregate, 11.52 to 13.76 parts of silica fume, 160 to 185 parts of mixing water, 3.2 to 3.8 parts of a water reducing agent, 17.28 to 20.64 parts of gneiss stone powder and 6.12 to 7.36 parts of a sulfate corrosion resistant agent, the preparation method of the magnesite concrete comprises the following steps: mixing and stirring all the raw materials except the mixing water and the water reducing agent, then adding the mixing water and the water reducing agent, and continuously stirring to obtain the magnesite concrete with high sulfate corrosion resistance. The magnesite concrete disclosed by the invention has relatively strong mechanical property and sulfate corrosion resistance and excellent durability.
本申请涉及菱镁矿混凝土领域，具体公开了一种高抗硫酸盐侵蚀的菱镁矿混凝土及其制备方法。菱镁矿混凝土包括以下重量份的组分：水泥360‑430份、粗骨料1128.5‑1146.6份、细骨料663‑689份、硅灰11.52‑13.76份、拌和水160‑185份、减水剂3.2‑3.8份、片麻岩石粉17.28‑20.64份、抗硫酸盐腐蚀剂6.12‑7.36份；其制备方法为：先将除拌和水和减水剂以外的所有原料混合搅拌，然后加入拌和水和减水剂继续搅拌，得到高抗硫酸盐侵蚀的菱镁矿混凝土。本申请的菱镁矿混凝土具有较强的力学性能及抗硫酸盐侵蚀性能，耐久性能优异。
