The invention relates to the technical field of concrete, and particularly discloses corrosion-resistant and rust-resistant mass concrete for coastal areas and a preparation process thereof. The mass concrete is prepared from the following raw materials in parts by weight: 250 to 300 parts of cement, 100 to 120 parts of fly ash, 20 to 25 parts of an efficient anti-cracking expanding agent, 30 to 40 parts of a corrosion inhibitor, 20 to 30 parts of a preservative, 700 to 730 parts of sand, 1000 to 1100 parts of gravel, 10 to 15 parts of a polycarboxylic acid efficient retarding and water reducing agent and 100 to 120 parts of water. The high-efficiency anti-crack expanding agent comprises a high-efficiency anti-crack expanding agent solvent and a high-efficiency anti-crack expanding agent microcapsule in a weight ratio of (2.5-1): 1, the wall material of the high-efficiency anti-crack expanding agent microcapsule is a solid polymer embedded with cuprous chloride solid particles, and the core material contains the high-efficiency anti-crack expanding agent and a surfactant. The corrosion resistance, the rust resistance, the crack resistance and the long-acting durable repairability of the mass concrete are improved.
本申请涉及混凝土技术领域，具体公开了一种沿海地区抗腐蚀阻锈大体积混凝土及其制备工艺。所述大体积混凝土由包含以下重量份的原料制成：水泥250‑300份、粉煤灰100‑120份、高效抗裂膨胀剂20‑25份、阻锈剂30‑40份、防腐剂20‑30份、砂子700‑730份、碎石1000‑1100份、聚羧酸高效缓凝减水剂10‑15份和水100‑120份；高效抗裂膨胀剂包括重量比为（2.5‑1）：1的高效抗裂膨胀剂溶剂和高效抗裂膨胀剂微胶囊，高效抗裂膨胀剂微胶囊的壁材为嵌有氯化亚铜固体颗粒的固体聚合物，芯材内含有高效抗裂膨胀剂和表面活性剂。本申请提高了大体积混凝土的抗腐蚀性、阻锈性、抗裂性和长效耐久修复性。
