Ultra high performance concrete(UHPC)--- AT-UHPC

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 House-building formwork system in large quantities and long-distance harmless transportation.

Facade elements on UHPC base are resistant to environmental influences. Facades or facade elements can be made very thin. By thin-layer Construction Materials and thus low weight of these elements are easier to install.

High Strength Concrete is several times more wear- and corrosion-resistant than standard concretes.

UHPC as flooring systems are extremely durable in all temperature ranges to mechanical loads.

Features of Beijing Lijian UHPC products

Super retarding technology

The opening time is effectively extended, and the expansion degree of 1.5h is ≥ 600mm, which promotes UHPC to enter the era of commercial mixing and effectively improves the uniformity of on-site mixing materials

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

Ultra high mechanical properties

The core component of composite material coordinates the relationship between opening time and early age strength, and the compressive strength of standard curing for 7 days is ≥ 150MPa
