Rapid-setting and fibre-reinforced dry spray structural repair concrete
Application
- Rapid repairs to structures within tidal zones.
- Repairs to dock walls.
- Repairs to coastal structures.
- Structural repairs to jetties, piers, sea walls, quays and docks.
- Repairs to river bridge abutments or piers.
- Primary linings to underground workings.
- Structural repairs to concrete beams, columns and soffits.
- Repairs to railway bridge and viaduct soffits.
Description
Rapid-setting and fibre-reinforced dry spray structural repair concrete designed to give high strength, low rebound, low wastage and to maxmise application thickness. Added alkali-resistant glass fibres give higher tensile strength, reduce shrinkage cracking and rebound.
Containing graded inert limestone aggregates and dust suppressants, webercem spray RSF has conformity testing to BS EN 1504-3 and meets the requirements for a Class R4 repair product.
Features and benefits:
- Rapid setting concrete allows work to continue in tidal zones.
- Rapid set prevents wash out from tidal action or flowing water.
- Economical with low rebound.
- Fibres help improve resistance to cracking and adhesion to concrete substrates.
- Extra high build – up to 400 mm thickness can be applied in one pass to vertical faces.
- Total chloride ion content does not exceed 0.05% of the weight of cement. No calcium chloride or admixtures containing chloride salts are used.
- Good resistance to salts absorption.
