RS-D1
 

RS-D1 is a rapid hardening shotcrete material, for dry-process applications. This product is a pre-blended, pre-packaged, dry-process shotcrete material powered by Rapid Set® technology, containing controlled blended aggregates and other carefully selected components. It has greatly enhanced shooting characteristics, providing greatly reduced setting times and very rapid strength development.

• Very high early strength for a reduced construction schedule
• Improved performance in presence of running water
• Air-entrainment provides superior resistance to freeze-thaw cycling and salt-scaling resistance
• Allows earlier re-opening of traffic lanes on bridges, and earlier re-entry times in tunnels and parking garages
• Low modulus of elasticity and low drying shrinkage, reducing cracking potential
• Simplified curing method to accelerate construction schedule

4. PROCEDURES

[For temperatures above 5 °C (40 °F)]

Surface Preparation (Rock Surfaces): All surfaces to be in contact with RS-D1 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).

Surface Preparation (Repair or Rehabilitation): All surfaces to be in contact with RS-D1 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 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). Application: Apply RS-D1 in accordance with the ACI 506 “Guide to Shotcrete” publication.

CURING
In order to reduce the construction schedule, RS-D1 was developed and tested using a simplified curing method consisting of applying two coats of a water-based curing compound that complies with ASTM C 309.

[For temperatures below 5 °C (40 °F)] 

Surface Preparation (Rock Surfaces): All surfaces to be in contact with RS-D1 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 rock surface, do not pre-wet the receiving surface. Pneumatically remove any free standing or other fine particles that may interfere with the bond between RS-D1 and the substrate.

Surface Preparation (Repair or Rehabilitation): All surfaces to be in contact with RS-D1 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 inch) clearance behind the reinforcing steel. The perimeter of the repair area should be sawcut a minimum of 20 mm (¾ inch). To avoid freezing of the interface between the shotcrete and the rock surface, do not pre-wet the receiving surface. Pneumatically remove any free standing or other fine particles that may interfere with the bond between RS-D1 and the substrate. Do not apply 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 and mixing water temperature must be maintained between 20° – 30°C (70° – 86°F).

Application: Apply RS-D1 in accordance with the ACI 506 “Guide to Shotcrete” publication.

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

Ingestion
May be harmful based on information for closely related materials.

Aspiration Hazard
Can cause lung damage if aspirated based on human experience.

STOT (Specific Target Organ Toxicity) – Repeated Exposure
Causes irritation of the respiratory system. Respiratory tract injury has been observed. Respirable crystalline silica in the form of quartz or cristobalite from occupational sources is listed by the International Agency for Research on Cancer (IARC) and National Toxicology Program (NTP) as a lung carcinogen. Prolonged exposure to respirable crystalline silica has been known to cause silicosis, a lung disease, which may be disabling. While there may be a factor of individual susceptibility to a given exposure to respirable silica dust, the risk of contracting silicosis and the severity of the disease is clearly related to the amount of dust exposure and the length of time (usually years) of exposure.
