Structural Concrete Protection

ADVANTAGES

  • Fire protection
  • Thermal upgrade
  • Thin solutions
  • Minimal fixings

Promat offers a number of solutions to address the increasing requirement for thermal upgrading and fire protection of semi-exposed concrete decks both in the conversion and refurbishment of existing and new building constructions.

Strengthening and upgrading structural systems to improve fire performance of an existing building is a common building renovation activity. For upgrade projects, design engineers must deal with structures in which every element carries a share of the existing load.

The tendency of concrete to spall, or break up, in a fire can lead to loss of the insulating cover to the steel and reduction in overall thickness of the member. In some constructions, supplementary reinforcement is necessary to reduce these effects. The overall thickness and cover is determined by the properties of the aggregate used.

NOTE:

  1. Existing fire resistance of concrete floor (30-180 minutes with equivalent insulation) is with referenece to BS 8110: Part 2: 1985.
  2. 240 minute insulation may not be achieved for structural stability of a pre-stressed or reinforced floor that is at risk due to inadequate concrete cover.
  3. Equivalent insulation applies to all existing and upgraded fi re resistance.
