UHPC’s superior performance data and index
1、The high compactness and good working performance of UHPC make the surface that contacts with the template have a high degree of smoothness. The outside harmful medium is difficult to intrude into the UHPC, and the colorants and other components in the UHPC are not easily dissolved out. With this characteristic, UHPC can be used as the exterior decoration material of buildings, and the chromatic aberration is reduced to the minimum, which is more conducive to surface cleaning.
2、UHPC is a ultra-high strength cement-based material with high strength, high toughness and low porosity. Its basic preparation principle is that by increasing the fineness and activity of the component, without the use of coarse aggregate, the defects (pores and micro cracks) within the material are reduced to the least, so as to obtain ultra high strength and high durability.
3、Mechanical properties of UHPC

Creep coefficient | 0.3 | 0.8 |
Coefficient of thermal expansion | 11.8µm/m/°C | 11.8µm/m/°C |
4、Resistance to acid attack. UHPCis exhibiting high resistance, even under severe conditions (the general concrete will be destroyed), and it’s resistance ability can make it be exposed to various erosion elements (such as calcium sulfate, sodium sulphate, acetic acid, ammonium sulphate, nitrate, sea water and distilled water).
5、UHPC is an Ultra High Performance Concrete (UHPC) which is developed from fine and high strength aggregate. The aggregate size combination has been optimized, so it is the lowest porosity concrete in the market. Because Ductal UHPC uses a specific combination of materials, it is suitable for the production of narrow and tiny components and these components have high durability (abrasive resistance, carbonation, chloride permeability and freezing-thawing resistance, etc.), which are far higher than the traditional concrete materials, such as at least 1000 times lower oxygen permeability. The hollowing out rate can be made to 50~70%.
6、The excellent performance of the material itself and the premixed pouring process make the product quality more stable and controllable, and it is not easy to crack.
7、Freeze-thaw test (300 cycles) 100% don’t change
•Ice salt denudation<0.0131b/M2, capillary porosity<1%
•HRT cycles 100%
•Abrasion resistance (relative volume loss index)1.7
•Oxygen permeation<10—9M2, total porosity3-6%
•Carbonization depth<0.02in
8、Way to install: both open installation and concealed installation are acceptable.
UHPC Outdoor Granite-Effect Flooring: Durable and Aesthetic Solutions for Modern Outdoor Spaces
Outdoor flooring requires materials that combine durability, weather resistance, and aesthetic appeal. Traditional flooring solutions such as natural stone, standard concrete, or asphalt often face challenges like cracking, corrosion, fading, and heavy maintenance. UHPC Outdoor Granite-Effect Flooring leverages ultra-high-performance concrete technology to address these issues, offering exceptional strength, longevity, and design flexibility.
This article explores the material properties, advantages, design versatility, installation considerations, and applications of UHPC granite-effect flooring, highlighting why it is increasingly used in urban landscapes, commercial plazas, residential patios, and public walkways.
Ultra-High Performance Concrete (UHPC) is a composite material engineered for superior durability and strength. Its key components include:
High-grade cement and fine aggregates
Fiber reinforcements for tensile and flexural strength
Chemical admixtures to enhance workability, curing, and performance
UHPC offers compressive strengths often exceeding 120 MPa, very low permeability, excellent abrasion resistance, and high tensile and flexural strength. These properties make it ideal for outdoor flooring in high-traffic and environmentally exposed areas.
Compared with natural stone, standard concrete, or asphalt, UHPC granite-effect flooring offers:
Durability: Resists cracking, wear, and structural degradation
Weather resistance: Withstands freeze-thaw cycles, UV radiation, and moisture penetration
Low maintenance: Requires minimal cleaning and no periodic sealing
Design flexibility: Supports various textures, colors, and finishes, including granite-effect aesthetics
These features make UHPC flooring a long-lasting and cost-effective solution for diverse outdoor environments.
Outdoor surfaces are exposed to rain, sunlight, temperature fluctuations, and pollution. UHPC flooring’s dense microstructure prevents water ingress and surface degradation, ensuring long-term stability and performance. Granite-effect finishes maintain color and texture even under prolonged UV exposure and heavy foot traffic.
Fiber-reinforced UHPC provides exceptional tensile and flexural strength, allowing granite-effect panels to support pedestrian traffic, light vehicles, and landscaping equipment without cracking or deformation. This makes them suitable for commercial plazas, pedestrian walkways, and public parks.
UHPC flooring exhibits superior resistance to abrasion, chemical exposure, and environmental pollutants. The granite-effect surface maintains its appearance and texture, reducing maintenance needs and ensuring safety in public and private spaces.
The granite-effect finish combines natural stone visuals with the structural advantages of UHPC. Designers can choose from:
Smooth, polished surfaces for modern urban designs
Textured or sandblasted finishes for slip resistance and natural stone appearance
Pigmented or patterned surfaces to match architectural and landscape aesthetics
