Reinforcing steel bar wrapping mode type seabed concrete and preparation method thereof
The invention discloses a reinforcing steel bar wrapping mode type seabed concrete. The seabed concrete comprises the following main components: cement, water, sand, stones, an air entraining agent, fly ash, a water reducing agent and an additive. Through rosin resin, lignosulfonate, a naphthalene sulfonate formaldehyde polymer, high aluminum powder, a sodium sulfate aqueous solution, silicic acid and fly ash, the anti-permeability performance of the concrete can be effectively improved, seawater is prevented from permeating into the concrete to influence the interior of the concrete, and the service life of the concrete is prolonged; meanwhile, a chloride ion permeation resistant film layer can be formed on the outer surface layer of the reinforcing steel bar in the construction process, the service life is prolonged by 1-2 times, and the problems that most of concrete on the market is poor in corrosion resistance and strength, prone to being impacted by objects in the sea and corroded by organisms and seawater in the sea in the seabed environment and the like are solved; the concrete can be quickly abraded and fractured, so that the use requirement of seabed protection cannot be met.
本发明公开了一种钢筋包模式海底用混凝土，所述海底用混凝土的主要成分为：水泥、水、砂、石子、引气剂、粉煤灰、减水剂和添加剂。本发明通过松香树脂、木质素磺酸盐、萘磺酸盐甲醛聚合物、高铝粉、硫酸钠水溶液、硅酸和粉煤灰，能够有效增加混凝土的抗渗性能，防止海水渗透入混凝土的内部，对其内部造成影响，提高了混凝土的使用寿命，同时施工过程中能在钢筋外表层形成一种抗氯离子渗透的膜层，延长使用寿命1‑2倍，解决了现有市面上大多数的混凝土抗腐蚀和强度较差，在海底的环境中，容易受到海中物体的撞击和海中生物和海水的腐蚀等等，都会导致混凝土快速磨损和破裂，无法满足海底保护使用需求的问题。
