Durable concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, in particular to durable concrete and a preparation method thereof, and the durable concrete comprises the following raw materials in parts by mass: 150-230 parts of Portland cement, 80-120 parts of an additive, 45-78 parts of a reinforcing agent, 12-23 parts of an anti-freezing agent and the balance of water. The additive is added, so that the internal structure of the concrete is more stable, the compression resistance and durability of the concrete are improved, the prepared concrete has the advantages of being not prone to cracking, good in workability, high in compressive strength, good in freezing resistance and the like, and the reinforcing agent is added, so that the concrete has high compactness and good anti-permeability, and the concrete has the advantages of being good in water resistance and water resistance. According to the present invention, the dissolution of heavy metal ions is effectively avoided, the compressive strength and the flexural strength of the concrete are improved, the shrinkage deformation of the concrete is reduced, the durability is improved, the service life is prolonged, and the raw materials are mixed in a plurality of steps so as to achieve good dispersibility between the raw materials, and improve the workability and the durability of the concrete mixture.
本发明涉及混凝土制备技术领域，尤其为一种耐久性混凝土及其制备方法，耐久性混凝土包括如下质量份数的原料：硅酸盐水泥150‑230份、外加剂80‑120份、加强剂45‑78份、防冻剂12‑23份和余量水。本发明外加剂的加入使混凝土内部结构更加稳固，提高混凝土的抗压及耐久性能，使制得的混凝土具有不易开裂、和易性好、抗压强度高、抗冻性好等优点，加强剂的加入不仅能使混凝土具有较高的密实性，使混凝土具有良好的抗渗性，有效避免重金属离子的溶出，且提高混凝土的抗压抗折强度，减少混凝土的干缩变形，改善耐久性，延长使用寿命，同时通过分多个步骤混合原料，使各原料之间的分散性较好，提高混凝土混合物的和易性和耐久性。
