The invention discloses a nano-reinforced phase-change anti-freezing concrete mixture and a preparation method thereof. The nano-reinforced phase-change anti-freezing concrete mixture is prepared from the following raw materials in parts by weight: 365 parts of cement, 1031 parts of gravel, 732.5-735.5 parts of sand, 165 parts of water, 75 parts of fly ash, 8 parts of a water reducing agent, 36.5 parts of a phase-change material and 4-7 parts of a nano-material. The preparation method comprises the following steps: uniformly mixing the raw materials to obtain the nano-reinforced phase-change anti-freezing concrete mixture. Through cooperation of the phase change material and the nanometer material, the thermal performance of the concrete is improved, the freeze-thaw resistance of the concrete is improved, and meanwhile it is guaranteed that the concrete has the strength needed by an engineering structure.
一种纳米增强相变抗冻混凝土拌合料及其制备方法，包括如下重量份的原料：水泥365份、碎石1031份、砂732.5‑735.5份、水165份、粉煤灰75份、减水剂8份、相变材料36.5份以及纳米材料4‑7份；制备方法是将原料混合均匀后，得到纳米增强相变抗冻混凝土拌合料；本发明通过相变材料和纳米材料的配合，改善混凝土的热学性能，提高混凝土抗冻融性能，同时保证混凝土具有工程结构所需的强度。
