Admixture for delayed coagulation type underwater non-dispersible concrete and preparation method thereof
The invention discloses a water reducing agent which is prepared by compounding the following components in percentage by mass: 3-6% of an HN-01 retarding component, 1-5% of a CF-01 flocculation component, 1-5% of a water reducing component, 1-5% of an inorganic dispersion component, 1-5% of other components and the balance of water. 10 to 14 percent of a CF-01 flocculation component; 35-38% of a water reducing component; 2-5% of an inorganic dispersion component; 0.1 to 0.8 percent of other components; and the balance of water. The HN-01 retarding component is an inorganic and organic composite modified super retarder; the CF-01 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.
本发明公开了由HN‑01缓凝组分、CF‑01絮凝组分、减水组分、无机分散组分、其他组分和水复配而成，各组分质量百分比为：HN‑01缓凝组分3‑6%；CF‑01絮凝组分10‑14%；减水组分35‑38%；无机分散组分2‑5%；其他组分0.1‑0.8%；其余为水；所述HN‑01缓凝组分为无机+有机复合改性超缓凝剂；所述CF‑01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。
