Ocean engineering concrete premix and preparation method thereof
The invention belongs to the technical field of ocean engineering materials, and particularly relates to an ocean engineering concrete premix and a preparation method thereof.The concrete premix is prepared from, by weight, sulfate-resistant cement, machine-made sand, gravel, ground mineral powder, a composite expanding agent, a nano anti-seepage agent, fibers, latex powder, a water reducing agent and an anti-dispersing agent. The preparation method of the premix comprises the following steps: step 1, sequentially adding sulfate-resistant cement, machine-made sand, broken stones, ground mineral powder, a composite expanding agent, a nano anti-permeability agent, fibers, latex powder, a water reducing agent and an anti-dispersing agent into a zero-gravity mixer in proportion; 2, after all the raw materials are added, continuously stirring for 3-5 minutes to prepare a concrete premix; and 3, stirring the concrete premix and water at the construction site according to a ratio of 100: 13. The beneficial effects of the invention are that: the cement mortar has high bonding degree with concrete, good anti-seepage pressure, large compressive strength, excellent breaking strength, good corrosion resistance, low industrial cost and long service life.
本发明属于海洋工程材料技术领域，具体涉及一种海洋工程混凝土预混料及其制备方法，混凝土预混料包含以下重量份的原料制成：抗硫酸盐水泥、机制砂、碎石、磨细矿粉、复合膨胀剂、纳米抗渗剂、纤维、乳胶粉、减水剂、抗分散剂，其中预混料的制备方法包括步骤一：将抗硫酸盐水泥、机制砂、碎石、磨细矿粉、复合膨胀剂、纳米抗渗剂、纤维、乳胶粉、减水剂、抗分散剂，依次按比例加入无重力混合机；步骤二：将全部原料加完后继续搅拌3～5min制成混凝土预混料；步骤三：施工现场混凝土预混料与水呈100:13的比例进行搅拌。有益效果在于：本设计方案的与砼粘结度高，抗渗压力好、抗压强度大、抗折强度优、耐腐蚀性好、工业成本低，使用寿命长。
