Highly anti-freezing pervious concrete as well as preparation process and application thereof
The invention relates to the technical field of pervious concrete, and particularly discloses highly anti-freezing pervious concrete as well as a preparation process and application thereof. The high anti-freezing pervious concrete is prepared from the following raw materials in parts by weight: 15 to 25 parts of belite-sulphoaluminate cement, 60 to 70 parts of aggregate, 5 to 10 parts of iron aluminate mineral admixture, 1 to 2 parts of anhydrite, 0.3 to 0.5 part of polymer rubber powder, 0.01 to 0.02 part of calcium stearate, 0.001 to 0.002 part of cerium oxide and 8 to 12 parts of mixing water. According to the technical scheme provided by the invention, the complexity and hydrophobic property of pore channels in the cement hardened slurry are improved, so that the diffusion and transmission of water in the hardened slurry are inhibited, the freezing resistance of the pervious concrete is improved, and the service life of the pervious concrete is prolonged.
本发明涉及透水混凝土技术领域，具体公开一种高抗冻透水混凝土及其制备工艺与应用。所述高抗冻透水混凝土的原料组成包括：贝利特‑硫铝酸盐水泥15～25重量份、骨料60～70重量份、铁铝酸盐矿物掺合料5～10重量份、硬石膏1～2重量份、聚合物胶粉0.3～0.5重量份、硬脂酸钙0.01～0.02重量份、氧化铈0.001～0.002重量份、拌合水8～12重量份。本发明的技术方案通过提高其中水泥硬化浆体中孔道的复杂性以及疏水特性，从而抑制水分在硬化浆体中的扩散传输，从而提高了透水混凝土的抗冻性，提高其服役寿命。
