King RS-S10 SCC Concrete 30kg
20006465RS-S10 SCC 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
• Superior plastic properties provide a fluid mix with self-consolidating characteristics without bleeding or segregation
• Easily consolidated without rodding or vibrating
• Properties similar to conventional concrete, thus offering excellent compatibility to parent concrete
• Excellent bond to parent concrete without requiring a bonding agent
• Designed with natural normal-density non-reactive fine and coarse aggregates to eliminate potential alkali-aggregate reactivity (AAR)

USES
• Partial depth, formed repairs of concrete beams, columns, soffits, and/or shear walls in bridges, parking garages or other concrete structures
• Place RS-S10 SCC at a minimum thickness of 50 mm (2 inches)
• Use RS-S10 SCC for closed formed repairs only
PROCEDURES
Surface Preparation: All surfaces to be in contact with RS-S10 SCC 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: Place 75% of required water into mixer and slowly introduce entire bag of RS-S10 SCC. Add balance of required water slowly while mixer is running, not exceeding maximum recommended volume of water. Maximum recommended volume of water is 2.75 L (0.73 US gallon) per 30 KG (66 lb) bag. Continue mixing for a minimum of 3 minutes and stop only when material has obtained a consistent homogeneous mix.
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 must 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”.
Fill the formwork with water in order to fully saturate the substrate and formwork. Repair any leaks in the formwork, as the formwork should be watertight. Drain water before introducing the RS-S10 SCC. Gravity feed RS-S10 SCC into forms and allow mix to fully encapsulate any existing rebar. Rodding and vibrating of mix is not required. Forms should not be removed until mix has attained a minimum compressive strength of 25 MPa (3625 psi). Refer to ACI 347, “Guide to Formwork for Concrete”.
CURING
Curing is essential to optimize the physical properties of RS-S10 SCC and minimize plastic shrinkage. Protect from moisture loss 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 or after the removal of formwork. Curing is particularly critical in rapid moisture loss conditions such as high temperatures, high winds and low humidity.
