Fosroc Renderoc RG Structural Repair Mortar (25 kg)

Product Details

Free-flow, high strength micro-concrete for structural rehabilitation of columns, beams & foundations. ✅ Ideal for jacketing & retrofitting ✅ Packing: 25 kg bag �� Used in BMC, MHADA, PMC jobs in MumbaiRenderoc RG is used for repairs to damaged reinforced concrete elements, particularly where access is restricted and where vibration of the placed material is diffi cult or impossible. It is suitable for various structural strengthening measures such as encasement build-ups, jacketing, piletop encapsulation resin system, etc. Advantages   Gaseous expansion system compensates for shrinkage and settlement in the plastic state.   Can be pumped or poured into restricted locations.   Highly fl uid to allow for placement without vibration.   Pre-packed to overcome site-batched variations.   Rapid strength gain to facilitate early reinstatement.   High ultimate strengths and low permeability of cured repair.   Contains no chloride admixture.  Ensures piletop integrity as part of a waterproofi ng system Description Renderoc RG is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free-fl owing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fi llers, and additives which impart controlled expansion characteristics in the plastic state, while minimising water demand. The low water requirement ensures high early strength and long-term durability. For larger repairs, the mixed Renderoc RG may be modifi ed by the addition of 5mm to 12mm clean, graded, saturated surface dry aggregates at site. For exceptionally large repairs, the local Fosroc offi ce shall be consulted. Technical support Fosroc off ers a technical support package to specifi ers, end users and contractors as well as technical on-site assistance in locations all over the country. Design criteria Renderoc RG can be applied in sections upto 100mm deep. For larger sections, the addition of approved aggregates may be required. This will depend on the specifi c confi guration of the repair location. Fosroc offi ce shall be contacted for further information.
