Preparation method of anti-frost-crack concrete
The invention provides an anti-frost-crack concrete preparation method, and relates to the technical field of concrete processing, and the anti-frost-crack concrete preparation method comprises the following steps: S1, crushing: firstly, accurately weighing raw materials, then, sequentially putting the raw materials into a concrete crusher, starting the crusher, gradually increasing the rotating speed, ensuring that the raw materials are fully mixed for 20 minutes, and taking out the raw materials; uniformly mixing the raw materials until the raw materials are completely crushed into fine particles, and ensuring that large particles do not exist; s2, grinding: putting the crushed mixture into a ball mill for grinding, starting the ball mill, and setting proper grinding time in the grinding process. According to the anti-freezing concrete, the freezing point of the concrete can be effectively reduced by adding the anti-freezing agent, so that the freezing resistance of the concrete is improved, structural damage caused by freezing is prevented, and the toughness and durability of the concrete can be improved and cracks caused by freezing and thawing cycle are reduced by adding the polypropylene fibers, the phenolic fibers and the polyvinylidene chloride fibers.
本发明提供一种防冻裂的混凝土制备方法，涉及混凝土加工技术领域，包括如下步骤：S1，打碎，首先将原料准确称量，随后，将所述原料依次投入混凝土打碎机中，启动打碎机，并逐渐增加转速，确保原料充分混合，持续20分钟，直到原料完全被打碎成细小颗粒，确保混合均匀，无大块颗粒存在；S2，研磨，将打碎后的混合料放入球磨机中研磨，启动球磨机，并设置适当的研磨时间，研磨过程中。本发明中，通过加入抗冻剂，能够有效降低混凝土的冰点，从而增加混凝土的抗冻性，防止冻结引起的结构损伤，而加入的聚丙烯纤维、酚醛纤维、聚偏氯乙烯纤维则可以增加混凝土的韧性和耐久性，减少因冻融循环而引起的裂缝。
