Anti-freezing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-freezing concrete and a preparation method thereof.The concrete is prepared from cement, coarse aggregate, fine aggregate, water, mineral powder, fly ash, an additive, an anti-freezing agent, an air entraining agent, waste aluminum particles, a silane coupling agent, polyacrylonitrile fibers and thermal expansion microspheres; wherein the core material of the thermal expansion microsphere is polyacrylonitrile fiber powder and liquid alkane, and the wall material of the thermal expansion microsphere is a mixture of polyurea and polyvinyl chloride; the preparation method comprises the following steps: mixing the cement, the coarse aggregate, the fine aggregate, the mineral powder, the fly ash, the air entraining agent, the waste aluminum particles and the polyacrylonitrile fibers to prepare a primary mixture; and mixing the admixture and the antifreeze agent, adding the mixture into water, adding the silane coupling agent, mixing, adding the primary mixture, finally adding the thermal expansion microspheres, and stirring to obtain the antifreeze concrete. The method has the characteristic of improving the freeze-thaw resistance of the concrete.
本申请涉及混凝土领域，具体公开了一种抗冻混凝土及其制备方法，混凝土包括以下原料：水泥、粗骨料、细骨料、水、矿粉、粉煤灰、外加剂、抗冻剂、引气剂、废铝颗粒、硅烷偶联剂、聚丙烯腈纤维和热膨胀微球；其中，热膨胀微球的芯材为聚丙烯腈纤维粉和液体烷烃，壁材为聚脲和聚氯乙烯的混合物；其制备方法包括以下步骤：将水泥、粗骨料、细骨料、矿粉、粉煤灰、引气剂、废铝颗粒、以及聚丙烯腈纤维混合制得初混物；将外加剂和抗冻剂混合后计入水中，然后加入硅烷偶联剂，混合后加入初混物，最后加入热膨胀微球，搅拌后制得抗冻混凝土。本申请具有提高混凝土抗冻融性能的特点。
