King RS-S10 Concrete 30kg
20006464RS-S10 is a high performance, very rapid hardening, polymer-modified, pre-packaged concrete material. It is a pre-blended, pre-packaged, high performance, cementitious, concrete repair and construction material powered by Rapid Set® technology, containing a redispersible polymer, 10 mm (3/8 inch) stone and other carefully selected components.
• Very high early strength for reduced construction schedule
• Properties similar to conventional concrete, thus offering excellent compatibility to parent concrete
• Ideal for full depth repair, does not need to be extended
• Designed with natural normal-density non-reactive fine and coarse aggregates to eliminate potential alkali-aggregate reactivity (AAR)
• Membrane application possible in only 8 hours after placement*
• All KING products are manufactured using ISO 9001:2015 Certified Processes
*Earlier membrane application is possible under certain conditions. See the Membrane Application section for more detailed information.

PROCEDURES
Surface Preparation: All surfaces to be in contact with RS-S10 must be free from dust, oil, grease or any other foreign substances that may interfere with the bond of the material. Remove all delaminated or unsound concrete providing a roughened surface and a minimum of 25 mm (1 inch) clearance behind any corroded reinforcing steel. The perimeter of the repair area should be saw-cut a minimum of 20 mm (¾ inch). Clean the area to be repaired with potable water, leaving the concrete saturated but free of standing water (SSD).
Mixing: Mechanical mixing using a concrete drum-mixer, mortar-style mixer or drill-mixer is required when mixing RS-S10. Do not mix RS-S10 with a planetary mixer and do not mix RS-S10 manually. For a target slump of 200 mm (8.0″) to 265 mm (10.5″), place 2.20 L (0.58 US gallon) of water into mixer and slowly introduce entire bag of RS-S10. Only if additional water is required to meet the target slump slowly add additional water while mixer is running, not exceeding the maximum recommended water content of 2.45 L (0.65 US gallon) per 30 KG (66 lb) bag. Continue mixing for 3 minutes and stop only when material has obtained a consistent homogeneous mix.
If a slump lower than the target is desired (< 200 mm or 8.0″), place 1.90 L (0.50 US gallon) of water into mixer and slowly introduce entire bag of RS-S10. Add additional water as needed while mixer is running to achieve the desired slump, not exceeding the maximum recommended water content of 2.45 L (0.65 US gallon) per 30 KG (66 lb) bag.
Placing: When the ambient temperature is between 0 °C (32 °F) and 10 °C (50 °F), the temperature of the fresh concrete must be maintained between 21 °C (70 °F) and 30 °C (86 °F) to promote early-age strength gain. The substrate temperature should be maintained above 0 °C (32 °F), until the material has reached final set. When the ambient temperature is below 0 °C (32 °F), refer to ACI 306, “Guide to Cold Weather Concreting”. In warm weather, ice water may be used to cool mix temperature and avoid short working time. When ambient temperature is above 30 °C (86 °F), refer to ACI 305, “Guide to Hot Weather Concreting”.
Place material uniformly and consolidate by forcing it down to the surface of the parent concrete and around the underside of the rebar using a concrete vibrator, a steel trowel, a wood float or by rodding the material following ACI 309 R “Guide to Consolidating Concrete”, without causing segregation. Ensure material has filled all voids and completely encapsulated any exposed rebar in the area to be repaired. For slab finishing, the use of a wood or magnesium float is recommended.
CURING
Curing is essential to optimize the physical properties of RS-S10 and minimize plastic shrinkage. RS-S10 should be protected from moisture loss (i.e. covered with a plastic sheet) for only 3 hours after material has reached initial set. Alternatively, apply a water-based curing compound that complies with ASTM C 309 after material has reached initial set. Curing is particularly critical in rapid moisture loss conditions such as high temperatures, high winds and low humidity.
MEMBRANE APPLICATION
Always follow the recommendations of the membrane manufacturer and test the moisture content before applying a membrane. Contact the membrane manufacturer or your KING Technical Representative for any additional information.
