Analysis of Strength Indicators of UHPC Manufacturer Products: Qinglong UHPC Strength Performance Advantages

UHPC product strength indicators include compressive strength, flexural strength, tensile strength, elastic modulus, and more. High-quality UHPC should achieve a compressive strength of 120-150MPa, flexural strength of 15-25MPa, direct tensile strength of 8-12MPa, and elastic modulus of 45-50GPa. Through optimized mix proportions and process control, Qinglong UHPC achieves a compressive strength of 135-150MPa, flexural strength of 18-25MPa, and elastic modulus of 48-52GPa, with all indicators exceeding national standards.

Strength development characteristics: under standard curing, 24-hour strength ≥50MPa, 7-day strength ≥100MPa, 28-day strength ≥120MPa; steam curing can further improve early strength. Testing of Qinglong UHPC by a testing agency showed an average 28-day compressive strength of 145MPa with a coefficient of variation of only 4.2%, far below the 10% required by standards.

Compressive Strength Performance

Standard requirement ≥120MPa, Qinglong UHPC reaches 135-150MPa; high density with porosity ≤6%; stable strength development with coefficient of variation ≤5%; continuous long-term strength growth, with strength increasing 15%-20% after 1 year. Compressive strength is the fundamental indicator.

Flexural Strength Characteristics

Standard requirement ≥15MPa, Qinglong UHPC reaches 18-25MPa; significant fiber reinforcement effect with good toughness; load-deflection curve shows strain-hardening behavior; failure mode is multiple cracking, ensuring high safety. Flexural strength reflects toughness.

Tensile Strength Performance

Direct tensile strength of 8-12MPa, 10 times that of ordinary concrete; strain capacity up to 0.3%-0.5%; strong crack control with crack width ≤0.1mm; pronounced tensile hardening characteristics. Superior tensile performance.

Elastic Modulus Indicators

Elastic modulus of 45-52GPa with high stiffness; linear stress-strain relationship; minimal deformation with good dimensional stability; modulus matched with steel rebar for excellent collaborative performance. Elastic modulus affects deformation.

Strength indicators lead across the board. Qinglong UHPC high-performance products meet all demanding requirements.
