Key features of Beijing Lijian a-uhpc products

Ultra high mechanical properties

High Strength Concrete 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. House-building formwork system has high frost resistance, carbonization resistance, permeability resistance, chloride ion resistance and sulfate resistance
Microcrack self healing
Under the condition of high strain, Construction Materials 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
