Description

DURA® WP70/20
Wall Panel 70/20 is a thin wall panel manufactured using ultra-high performance ductile concrete (UHPdC). Each panel has a total height of 7 m and a total width of 2 m. The wall panel has multiple purposes such as it can be used in conjunction with Dura® PFS (Portal Frame System), serve as thin wall panel against wind/rain/sunshine/dust/spy. Besides, the wall panel can be customized to serve as acoustic panel against noise; security panel against thief; protective panel against blast and impact loading; impermeable membrane against highly corrosive compound and fire.

Features
  • DURA® WP70/20 consists of thin wall panel of 30 mm in thickness, two ribbed beams as wide as 75 mm and a base pad of 100 mm in thickness.
  • The UHPdC used for the DURA® WP70/20 has characteristic compressive strength ranges between 100 to 120 MPa, and characteristic flexural strength of 15 MPa.
  •  DURA® WP70/20 eliminates the use of conventional steel reinforcing bars and stirrups. All steel fibres used are made from high carbon steel wires with tensile strength of 2300 MPa.
  • Special lifting anchors are provided to improve the safety margin during handling and installation.
Advantages of DURA® WP70/20
  • DURA® WP70/20 is highly durable and impermeable. It is therefore suitable for use in extremely aggressive environments such as marine environments or chemically active plants.
  • DURA® WP70/20 is easy to install. Simple conventional drop-in anchors or pre-positioned bolts & nuts are used to connect the wall panel to the floors (except some grout maybe needed for uneven floor base).
  • No scaffolding, props or formwork are required over the entire installation, thus reducing construction site activities, improving safety margins and eliminating in-situ casting work.
  • DURA® WP70/20 is many times lighter than conventional R.C. wall system.
  • DURA® WP70/20 is guaranteed to be geometrically stable as they are steam-cured to minimized creep and long-term shrinkage.
  • DURA® WP70/20 is not only weather-proof, but can be also customized to fire-proof.
  • DURA® WP70/20 is aesthetically pleasing as its finish surface is smooth and colors of the wall are subjected to request.
  • DURA® WP70/20 is a durable structure that supports the "GREEN" visionary of sustainable development.
