Cement Canvas

Cement Canvas is a flexible composite material in which dry cement powder is embedded within a three-dimensional fiber matrix. When hydrated, it rapidly hardens to form a thin, concrete structure that is waterproof, fire-resistant, and durable, and is widely used in emergency engineering, slope protection, temporary construction, and creative design applications.To use, simply cut the Concrete Canvas to the required size, lay it in place, and thoroughly water or soak it. Water activates the cement, triggering the hydration process, after which it hardens into shape within 24 hours, forming a concrete layer 5–25 mm thick with a compressive strength of 10–50 MPa, comparable in performance to traditional concrete. Its key features are: soft and foldable before curing, making it easy to transport; strong, durable, and with a service life of over 20 years after curing.

Concrete Canvas (CC), also known as "cementitious fabric," is a flexible composite material pre-impregnated with dry mixed cement, structured like a "sandwich":

· Top layer: A wear-resistant, UV-protected polyethylene (PE) woven fabric that provides initial protection;

· Core layer: A three-dimensional fiber matrix uniformly embedded with specialized cement powder, serving as the "heart" of the hydration reaction;

· Bottom layer: A permeable PE or PVC film that retains moisture to promote hydration while preventing cement loss.

I. Core Advantages at a Glance

1. ‌Simple Construction‌: No mixing, formwork, or heavy machinery required—lightweight panels can be transported and installed by a single worker

2. ‌Rapid Curing‌: Shape remains adjustable up to 2 hours after watering; achieves 80% strength within 24 hours; light vehicles can traverse the surface after 72 hours

3. ‌Eco-Friendly‌: Uses 95% less material than traditional concrete, significantly reducing carbon emissions and aligning with green building principles

4. ‌Adaptable to Complex Terrains‌: Conforms seamlessly to irregular surfaces such as curves, slopes, and pipelines, minimizing earth excavation

5. ‌Waterproof and Fire-Resistant‌: Ultra-low permeability down to 10⁻¹¹ m/s, ensuring complete waterproofing; non-combustible with no open flame, low smoke, and minimal toxic gas emission during exposure to fire

II. Applications of Cementitious Textile: 

‌1. Emergency and Rapid Construction‌

· Temporary roads after disasters, flood embankments, and reinforcement of breached dams (e.g., Jiangxi flood relief in China, 2020)

· Emergency shelters (CCS Shelter), formable in as little as 40 minutes, habitable within 2 hours

‌2. Infrastructure Repair and Protection‌

· Pipe wrapping, bridge strengthening, tunnel lining

· Slope protection, riverbank and mine slope stabilization, as an alternative to shotcrete, preventing soil erosion

‌3. Environmental and Agricultural Applications‌

· Construction of corrosion-resistant troughs, drainage channels, and drought-resistant canals (already applied in Africa)

· Anti-seepage layers for reservoirs and water storage pits
