Key Features of the UHPC150 Series
Easy Construction: Self-consolidating workability with high slump-flow and low 1-h loss, enabling excellent pumpability and uniform consolidation for more consistent on-site quality.
Dual High Performance: Ultra-high compressive strength together with tensile strain-hardening toughness provides performance redundancy for critical load-bearing members.
Systematic Delivery: An integrated suite—prestressed duct grouting, structural grouting, and UHPC prefabrication(field-cast components—reduces multi-supplier coordination costs.
Customization: All products support custom development with matching technical services to optimize materials performance, construction efficiency, and environmental metrics.

Under direct tension, once after first cracking, steel fibers embedded in the dense cementitious matrix bridge the cracks and continue to transfer tensile stresses through fiber–matrix interfacial bond and shear, so the composite sustains high post-cracking tensile capacity and exhibits a metal-like tensile strain-hardening response.
