Basalt fiber modified anti-freezing concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses basalt fiber modified anti-freezing concrete and a preparation method thereof. The basalt fiber modified anti-freezing concrete is obtained by putting a concrete mixture into a mold and curing, the slurry modifier comprises ferric nitrate and calcium hydroxide, and the molar ratio of the ferric nitrate to the calcium hydroxide is 2: (2.1-3). By adding the slurry modifier disclosed by the invention into a concrete mixture, the salt freezing damage degree can be reduced, and the service life of concrete structures such as concrete canals can be prolonged.
本申请涉及混凝土技术领域，具体公开了一种玄武岩纤维改性抗冻混凝土及其制备方法。玄武岩纤维改性抗冻混凝土由混凝土拌和物经过入模养护得到，浆体改性剂的组分包括硝酸铁和氢氧化钙，硝酸铁与氢氧化钙的摩尔比为2:(2.1‑3)。通过在混凝土拌和物中添加本申请的浆体改性剂，能够降低盐冻破坏的程度，有助于延长混凝土水渠等混凝土结构的服役年限。
