A UHPC shading elements create

Ultra-high-performance concrete- UHPC is an advanced cementitious material with high strength and excellent durability. It offers the potential to become a practical solution to improve the sustainability of buildings and other infrastructure components. For the past two decades, UHPC is gaining increased interest in many countries with the usage ranging from building components, bridges, architectural features, repair and rehabilitation, vertical components such as windmills towers and utilities towers to oil and gas industry applications, off-shore structures, hydraulic structures and overlay materials.

UHPC is an ultra-high performance cement-based composite with ultra-high strength (compressive strength ≥ 120MPa, tensile strength ≥ 5MPa), high toughness and high durability

A-uhpc, steam curing free UHPC product, has the characteristics of steam curing free, ultra-high strength, high toughness and low shrinkage.

Technical indicators of a-uhpc products

Key features of Beijing Lijian a-uhpc products

Ultra high mechanical properties

It has ultra-high compressive strength (compressive strength ≥ 160MPa after curing at room temperature for 28 days), tensile strength and high toughness

Ultra high durability

The matrix is dense, and the internal pore structure is not connected. It has high frost resistance, carbonization resistance, permeability resistance, chloride ion resistance and sulfate resistance

Microcrack self healing

Under the condition of high strain, it still has good self healing ability of microcracks

Low carbon environmental protection

The carbon emission per unit intensity is reduced by 40%, which is energy-saving, material saving, low-carbon and environmental protection

AT-UHPC，Gaobaotan UHPC products. 1.5h expansion ≥ 600mm, 7d strength ≥ 150MPa. Improve the construction performance of traditional UHPC and realize the standardized production of UHPC commercial concrete in large quantities and long-distance harmless transportation.
