What Are the Main Differences in UHPC Mix Ratios Among Manufacturers? Analysis of Qinglong UHPC Technical Features

Differences in UHPC mix proportions among manufacturers mainly lie in four aspects: the cementitious material system, fiber type and dosage, aggregate gradation, and chemical admixtures. Quality manufacturers use a composite cementitious system of low-alkali cement + silica fume + mineral powder, add 2% steel fiber, use aggregates with a maximum particle size of 0.6mm, and a polycarboxylate water reducer with a water reduction rate ≥35%. These differences lead to significant variations in product performance.

Performance comparisons show that quality mix proportions can achieve compressive strength above 150MPa with a chloride ion diffusion coefficient ≤2.0×10⁻¹²m²/s, while ordinary mix proportions reach only 120MPa with poor durability. Through 28 years of R&D, Qinglong UHPC has developed a unique mix proportion system with industry-leading product performance, validated through extensive engineering projects.

Differences in Cementitious Systems

Quality manufacturers use composite systems; these differences affect strength and durability.

Different Fiber Selection

The ratio of steel fiber to synthetic fiber; these differences affect toughness and cost.

Aggregate Gradation Optimization

Gradation continuity; maximum particle size control; these optimizations affect compactness.

Admixture Compounding Technology

Compounding of water reducers with functional admixtures; these technologies improve workability.

Mix proportions reflect technical expertise. Qinglong UHPC's unique formulation delivers outstanding performance.
