Targeting material for improving anti-freezing and anti-corrosion performance and preparation of anti-freezing and anti-corrosion C30 concrete
The invention relates to a material for filling C30 concrete pores with particles, preventing external water and sulfate ions from entering the concrete and further improving the freeze-thaw resistance and corrosion resistance of the C30 concrete. The material comprises the following components in percentage by weight: 60-47% of cement (mc), 10-20% of fly ash (mf), 10-20% of mineral powder (msf), 10-20% of natural sand (mm), 10-20% of broken stone (mcs) and 10-20% of a targeting material (mz), (20%-27%): (20%-26%): (1.11%-1.43): (2.72%-3.36%): (3.15%-4.30%). The water reducing agent adopts an external doping method, and the doping amount of the water reducing agent is 1-2% of that of the cementing material. The C30 concrete has the beneficial effects that the targeting material is doped into the C30 concrete component, the targeting material is mainly used for efficiently filling pores of the C30 concrete, and the concrete is denser in a particle filling effect at the early stage of hydration, so that the number of multiple harmful pores and harmful pores in a pore structure is reduced, and the pore structure is more compact. Finally, the freeze-thaw resistance and the sulfate corrosion resistance of the concrete are improved.
本发明涉及了一种针对具有微粒填充C30混凝土孔隙、阻断外部水和硫酸盐离子进入混凝土内部，进而提高C30混凝土抗冻融、抗腐蚀的一种材料，其组分及配合比为：水泥(mc):粉煤灰(mf):矿粉(msf):天然砂(mm):碎石(mcs):靶向材料(mz)=(60%‑47%);(20%‑27%):(20%‑26%):(1.11‑1.43):(2.72‑3.36):(3.15%‑4.30%)。减水剂采用外掺法，掺量为胶凝材料的1~2%。本发明的有益效果：通过在C30混凝土组分中掺入靶向材料，靶向材料的作用主要为高效填充C30混凝土孔隙，在水化前期的微粒填充效应中使得混凝土更加密实，从而降低了孔结构中多害孔和有害孔的数量，最终提高了混凝土的抗冻融、抗硫酸盐腐蚀性能。
