Ultra-long delayed coagulation type underwater non-dispersible concrete admixture and preparation method thereof
The invention discloses an ultra-long delayed coagulation type admixture for underwater non-dispersible concrete and a preparation method of the admixture. The admixture is prepared by compounding an HN-02 delayed coagulation component, a CF-02 flocculation component, a water reducing component, an inorganic dispersion component, other components and water. The HN-02 retarding component accounts for 6-10% of the total weight, the CF-02 flocculation component accounts for 12-19% of the total weight, the water reducing component accounts for 38-40% of the total weight, the inorganic dispersing component accounts for 2-5% of the total weight, the other components account for 0.1-0.8% of the total weight, and the balance is water. The HN-02 retarding component is an inorganic and organic composite modified super retarder; and the CF-02 flocculation component is a powdery water-soluble organic high polymer non-dispersing agent. The concrete admixture disclosed by the invention has multiple functions of retarding, flocculating, water reducing and the like, and can prolong the plasticity maintaining and setting time of concrete, improve the dispersion resistance of the concrete and regulate the viscosity of the concrete at the same time.
本发明公开了一种超长缓凝型水下不分散混凝土用外加剂及其制备方法，所述外加剂由HN‑02缓凝组分、CF‑02絮凝组分、减水组分、无机分散组分、其他组分和水复配而成。HN‑02缓凝组分占总重的6‑10%，CF‑02絮凝组分占总重的12‑19%，减水组分占总重的38‑40%，无机分散组分占总重的2‑5%，其他组分占总重的0.1‑0.8%，其余为水；所述HN‑02缓凝组分为无机+有机复合改性超缓凝剂；所述CF‑02絮凝组分为粉末状水溶性有机高聚物不分散剂。本发明涉及的混凝土外加剂兼具缓凝、絮凝、减水等多项功能，可延长混凝土的保塑及凝结时间的同时，提高混凝土的抗分散性能，并调节混凝土的黏度。
