Descrição do produto

A UHPC shading elements create

O concreto uhpc ultra-alto desempenho é um material cimentício avançado com alta resistência e excelente durabilidade. Oferece o potencial para se tornar uma solução prática para melhorar a sustentabilidade dos edifícios e outros componentes de infraestrutura. Nas últimas duas décadas, a UHPC está ganhando maior interesse em muitos países com o uso que varia de componentes de construção, pontes, características arquitetônicas, reparo e reabilitação, componentes verticais, como torres de moinhos de vento e torres de utilidades para aplicações de petróleo e gás, off-shore estruturas, estruturas hidráulicas e materiais de sobreposição.

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

Features of Beijing Lijian 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

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