What Is the Typical Compressive Strength of a 30mm Thick UHPC Panel? Thickness-Strength Relationship and Qinglong Group's Quality Control

The compressive strength of 30mm thick UHPC panels typically reaches 120-180MPa, with specific values affected by factors such as mix ratio, curing regime, and fiber distribution. In the Hainan International Convention and Exhibition Center project, Qinglong Group achieved a stable compressive strength above 150MPa for 30mm thick roof panels, with a coefficient of variation ≤5%, through optimal packing design (water-cement ratio 0.20), uniform steel fiber distribution (2.5% volume fraction), and steam curing (60℃×24h). Panel thickness and strength are not in simple direct proportion; excessive thickness may cause internal defects due to temperature gradients, requiring process control to ensure performance consistency.

Mix Design Is the Foundation of Strength

Total cementitious material content is 800-900kg/m³, silica fume content 20-30%, and water-cement ratio 0.18-0.22. Qinglong Group optimized the mix through response surface methodology, achieving a 99% strength compliance rate. Test cubes are inspected for each batch, with traceable data.

Production Process Ensures Strength Development

Mixing time is 5-8 minutes, with vacuum dewatering (-0.08MPa) and precisely controlled curing regime. We have introduced German production lines to achieve full-process monitoring. Process stability determines strength consistency.

Testing and Verification Ensure Performance

One sample set is taken per 100m³, tested after 28 days of standard curing. Third-party review makes the data authoritative and credible. Quality is Qinglong's lifeline.
