GRADATION

• By default King® RS-D1 & King® RS-D1 ST are blended to meet ACI 506 “Guide to Shotcrete”, Table 1.1, Gradation No. 1
• King® RS-D1 G2 & King® RS-D1 ST G2 are blended to meet ACI 506 “Guide to Shotcrete”, Table 1.1, Gradation No. 2

12 months in original packaging, unopened

Material should be stored in a dry, covered area, protected from the elements. For optimum performance it is recommended to store the material between 5°C ( 40°F) and 35°C (95°F) . 

Underground environments

Physical properties may be adversely affected if material is stored in temperatures below 5°C ( 40°F), material stored below these temperatures should be allowed to warm to ambient underground temperatures before shooting.For optimum performance it is recommended to store the material between 5°C ( 40°F) and 35°C (95°F) .

ROCK SURFACES: All surfaces to be in contact with product must be free from dust, oil, grease or any other foreign substances that may interfere with the bond of the material. Remove all loose or delaminated rock. Clean the area with potable water, leaving the substrate saturated but free of standing water (SSD).

REPAIR OR REHABILITATION: All surfaces to be in contact with product must be free from dust, oil, grease or any other foreign substances that may interfere with the bond of the material. Remove all loose or delaminated concrete providing a roughened surface and a minimum of 20 mm (¾ in) clearance behind any corroded reinforcing steel. The perimeter of the repair area should be saw-cut a minimum of 20 mm (¾ in). Clean the area to be repaired with potable water, leaving the concrete saturated but free of standing water (SSD)

ROCK SURFACES:All surfaces to be in contact with the product must be free from dust, oil, grease or any other foreign substances that may interfere with the bond of the material. Remove all loose or delaminated rock. To avoid freezing of the interface between the shotcrete and the parent concrete, do not pre-wet the receiving surface. Pneumatically remove any free standing or other fine particles that may interfere with the bond between the product and the substrate.

REPAIR OR REHABILITATION: All surfaces to be in contact with product must be free from oil, grease or any other foreign substances that may interfere with the bond of the material. Remove all loose or delaminated concrete providing a roughened surface and a minimum of 25 mm (1 in) clearance behind the reinforcing steel. The perimeter of the repair area should be sawcut a minimum of 20 mm (¾ in). To avoid freezing of the interface between the shotcrete and the parent concrete, do not pre-wet the receiving surface. Pneumatically remove any free standing or other fine particles that may interfere with the bond between the product and the substrate. Do not apply when ambient temperature is below or is expected to fall below -5 °C (20 °F) within six (6) hours following the application of shotcrete. Do not apply when temperature of receiving surface is below -5 °C (20 °F). Material and mixing water temperature must be maintained between +20 °C and +30 °C (70 °F and 86 °F).

Apply product in accordance with the ACI 506 “Guide to Shotcrete” publication.

OPTIMUM PERFORMANCE

• King® RS-D1 & King® RS-D1 ST should not be applied when ambient and substrate temperatures are below -5 °C (20 °F) or when ambient, substrate and material temperatures are above +35 °C (95 °F).
• For adverse temperatures, follow ACI recommendations for Cold/Hot Weather Concreting.

TEMPERATURES BELOW 5°C (40°F):

Do not apply King® RS-D1 when ambient temperature is below or is expected to fall below –5 °C (20 °F) within 6 hours following the application of shotcrete.

Do not apply when temperature of receiving surface is below –5 °C (20 °F). Material temperature should be maintained above 10 °C (50 °F) at the time of application.

In order to reduce the construction schedule, this product was developed and tested using a simplified curing method consisting of applying two (2) coats of a water-based curing compound in compliance with ASTM C309.

FOR APPLICATIONS AT TEMPERATURES BELOW 5 °C (40 °F)

Immediately after shotcrete reaches final set, apply two (2) coats of a resin-based liquid membrane curing compound approved for use in cold weather conditions.

Clean all tools and equipment immediately after use with water. Once hardened, material can only be removed mechanically.
