Renderoc Rapid is designed to accept traffic one hour after placement, enabling fast repairs and concrete replacements to take place, whilst minimising any traffic interruptions. The product is alkaline in nature and will protect embedded steel reinforcement. It may be used in both internal and external applications. When reinstating floor and pavement areas having a repair area greater than 10 m², the use of Paveroc is recommended. Advantages „ Rapid strength gain - will accept traffic in 1 - 2 hours „ High strength, abrasion and weather resistance „ Single component product eliminates site batching and March 2014 Page 1 March 2014 23 requires only the site addition of clean water „ Excellent bond to the concrete substrate „ Shrinkage compensated „ Contains no chloride admixtures Description Renderoc Rapid is supplied as a ready to use blend of dry powders which require only the site addition of clean water to produce a highly consistent, high strength reinstatement mortar which virtually self-compacts. The material is based on a blend of cements, graded aggregates, special fillers and chemical additives to provide a mortar with good handling characteristics, while minimising water demand. Renderoc Rapid exhibits excellent thermal compatibility with concrete and good water repellent properties. The low water requirement ensures fast strength gain and long-term durability. Technical Support Parchem offers technical support to specifiers, end-users and contractors, as well as on-site technical assistance. Design Criteria Renderoc Rapid is designed for horizontal use. The material should not be applied at less than 25 mm thickness. Renderoc Rapid may be applied up to a maximum thickness of 250 mm. Properties The following results were obtained from material mixed at w/p 0.125 (2.5 L / 20 kg) and cured at 23°C. Cure time Compressive strength (AS1478.2 - 2005) 1 hour: 20 MPa 2 hours: 25 MPa 4 hours: 30 MPa 1 day: 35 MPa 7 days: 45 MPa 28 days: 55 MPa Working Life: 10 minutes Initial Set: 20 - 25 minutes Final Set: 25 - 35 minutes Time to Pedestrian 1 - 2 hours Vehicular Traffic: Fresh Wet Density (AS1012.5 - 1999): 2200 kg / m³ Shrinkage (AS1012.13 - 1992): < 600 microstrain @ 28 days Note: Compressive strengths stated above were measured using cube samples. Test results obtained will vary if testing is carried out to an alternative standard or sample dimensions are used. Specification Clauses Steel reinforcement primer Where reinforcement has been exposed by the preparation process, the steel primer shall be Nitoprime Zincrich, a single component zinc-rich epoxy resin. The primer shall be an ‘active’ type, capable of avoiding the generation of incipient anodes in the immediately adjacent locations. It shall be fully compatible with the Renderoc system of concrete repair.. Rapid reinstatement mortar The rapid reinstatement mortar shall be Renderoc Rapid, a single component cement-based blend of powders to which only the site-addition of clean water shall be permitted. The cured mortar shall achieve 20 MPa @ 1 hour and 35 MPa @ 24 hours (@ 23°C). The product shall be capable of accepting pedestrian and vehicular traffic after 1 - 2 hours @ 23°C.
