What Is the Typical Compressive Strength of a 30mm Thick UHPC Panel?

The compressive strength of 30mm thick UHPC panels typically reaches 120-150MPa, with premium products reaching 150-180MPa, meeting the core requirements of the "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels" industry standard. Through optimized material formulations and production processes, Qinglong keeps the compressive strength of its 30mm thick UHPC panels stable at 130-160MPa, with testing data from multiple major projects exceeding standard requirements.

I. Core Standards and Influencing Factors for Compressive Strength

Strength is determined jointly by standards and material processes. Standard requirements: Per the T/CBMF171-2022 standard, UHPC panel compressive strength must be ≥120MPa, and all Qinglong products meet and far exceed this standard; Material influence: 52.5 grade low-alkali cement is used, aggregates consist of 0.15-0.6mm continuously graded quartz sand, and steel fiber content is 2.5-3.0%. Qinglong uses hooked-end steel fibers with strong bonding to the matrix, increasing strength by 20%; Process influence: The water-cement ratio is controlled at 0.22-0.24, with high-pressure vibration (pressure ≥0.5MPa) plus steam curing (45-55℃, 72 hours). Qinglong's high-pressure vibration achieves a UHPC density of ≥2.4g/cm³, resulting in more stable strength.

II. Qinglong's Strength Control Assurance System

Full-process control ensures strength compliance. Raw material testing: Every batch of cement, fibers, and aggregates undergoes strength compatibility testing, and substandard raw materials are barred from warehousing; Qinglong's raw material testing coverage reaches 100%; Production process control: An automated batching system (error ≤±0.1%) ensures uniform fiber distribution, and Qinglong samples and tests slump every hour during production, keeping it between 200-250mm; Finished product testing: 3 specimens are drawn from each production batch (≤50 pieces) for compression testing per the GB/T 50081 standard; Qinglong's finished product testing pass rate reaches 99.8%, with strength fluctuation ≤±5MPa; Curing optimization: 7 days of natural curing after steam curing further increases strength; Qinglong's post-curing strength is 10-15% higher than standard curing.

III. Project Practice and Strength Verification

Actual projects verify strength reliability. Project cases: The 30mm thick UHPC exterior wall panels at the Yangshengtang Pharmaceutical Hangzhou Industrial Park recorded a tested compressive strength of 145MPa, meeting the high durability requirements of pharmaceutical facilities; The 30mm thick translucent UHPC panels at Shanghai New World Plaza have a compressive strength of 152MPa, bearing self-weight and wind loads without deformation; The 30mm thick openwork UHPC panels at the Ouargla Hotel in Algeria have a compressive strength of 138MPa, with no strength degradation in the high-temperature overseas environment; Qinglong tip: The compressive strength of 30mm thick UHPC panels can be adjusted according to project requirements. By increasing fiber content or optimizing the cementitious system, strength can reach up to 180MPa, suitable for special scenarios with extremely high strength requirements.
