FDN: An Efficient, Mul-tifunctional Water Reducer

FDN-I – A highly efficient water-reducing agent

· Dosage: Powder: 0.5%–1.0% (by weight of cementing materials); Liquid: 1.5%–3.0% (by weight of cementing materials).

· Excellent water-reducing and dispersing effects, with a water reduction rate of 15% to 25%.

· Difference in Setting Time (Initial / Final): -90 min to +120 min;

· Air content ≤3.0%;

· Shrinkage ratio ≤ 135% ;

· Compressive Strength Ratio: 3d ≥ 130%, 7d ≥ 125%, 28d ≥ 120%.

· The slump of the concrete mixture can be increased by 10 cm to 20 cm; it exhibits no bleeding or segregation, thereby significantly improving the workability of the concrete.

· With a low dosage and high strength, it enables a 10% to 20% reduction in cement usage, improves the structure of hardened concrete, and significantly enhances its impermeability, frost resistance, corrosion resistance, and durabilit.

FDN-II: A slow-setting, high-efficiency water-reducing agent

· Dosage: 0.7%–1.5% (based on the weight of cementing materials);

· Excellent water reduction effect: water reduction rate ≥15%;

· It exhibits significant retarding effects, and the retardation time can be adjusted to meet varying engineering requirements;

· High Strength Enhancement: 7-day compressive strength ratio ≥ 125%; 28-day compressive strength ratio ≥ 120%;

· High efficiency in slump retention, particularly suitable for ready-mixed concrete requiring stringent slump control.
