A preblended cementitious repair concrete which fully complies with the Highways Agency Specification for Highway Works and Department of Transport specification BD 27/86 for a high strength flowing concrete. Contains non-reactive aggregates and a low soluble alkali cement content. The repair concrete can be applied to a range of thicknesses, minimum 15 mm. Contains RHPC and PFA to clause 1702, 5 mm non-reactive carboniferous limestone to clause 1704, microsilica and shrinkage compensating agents.
- Repair of concrete to bridge structures to Highways Agency (HA) model specification BD 27/86.
- Replacement of concrete to beams and crossheads.
- Repair of car parks, buildings, balconies and stairs.
- Coastal structural repairs and seawall reconstruction.
- Repairing concrete columns, beams, walls and soffits.
- Infill concrete and anchorage of bolts to large bolt pockets.
- For use under baseplates where thick sections are required to be grouted: 75–500 mm.
- Permanent structural repair concrete.
- Rapid strength development thus reducing repair possession times.
- Dimensionally stable, forms an integral bond to existing concrete and restores structural integrity with proven durability.
- Free-flowing repair concrete allowing formation of intricate falsework.
- Ideally suited in structural elements where reinforcement is congested.
- Shrinkage-compensated to avoid shrinkage cracks and enhance durability.
- Immediately after finishing, the exposed surfaces of the concrete shall be cured with wet hessian, polythene or frost blankets for at least 48 hours to prevent rapid loss of water.
- Formwork shall not be removed until the repair can support dead and imposed loads, the concrete should then be cured with a spray-on curing membrane, Weber.tec ritecure, for a minimum of 14 days.
