LR-D1

 

 

LR-D1 is a pre-blended, pre-packaged, dry-process shotcrete material containing Portland cement, air-entraining admixture, blended aggregates and other carefully selected components. This product provides low resistivity values and is specifically designed for use with cathodic protection systems.

• Enhances performance of cathodic protection system
• Air-entrainment provides superior resistance to freeze-thaw cycling and salt-scaling resistance
• Designed with natural normal-density non-reactive aggregates to eliminate potential alkali-aggregate reactivity (AAR)
• All KING products are manufactured using ISO 9001:2015 Certified Processes

See the Technical Data section for more detailed information.

SYNTHETIC FIBER
LR-D1 SY
• Synthetic fibers reduce cracking caused by intrinsic stresses
• Type III synthetic fiber in accordance with ASTM C 1116
• Grade FR Class I shotcrete in accordance with ASTM C 1480

GRADATION
• By default LR-D1 is blended to meet ACI 506 “Guide to Shotcrete”, Table 1.1, Gradation No. 1
• LR-D1 G2 is blended to meet ACI 506 “Guide to Shotcrete”, Table 1.1, Gradation No. 2

EXAMPLE:
For LR-D1 with a level 2 dosage of accelerator, with synthetic fibers and Gradation No. 2, the name of the product would be LR-D1 X2 SY G2.

3. USES

• Induced current applications including new construction and rehabilitation.
• Galvanic anode applications including new construction and rehabilitation.
• Use of a predampener in conjunction with dry-process accelerated shotcrete is not recommended. Contact your local KING Technical Representative.

4. PROCEDURES

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

5. CURING

Curing is essential to optimize physical properties of the shotcrete and minimize plastic shrinkage. LR-D1 should be cured immediately after material has reached initial set in accordance with ACI 308 “Guide to Curing Concrete”. Continuously moist cure for a minimum period of 7 days. Alternatively, moist cure for a minimum period of 24 hours and apply a curing compound that complies with ASTM C 309. Curing is particularly critical in rapid moisture loss conditions such as high temperatures, high winds and low humidity.

6. TECHNICAL DATA

The following data is representative of typical values achievable using proper application techniques as outlined in the ACI 506 “Guide to Shotcrete” publication. The data was obtained during project field tests and in-house shotcrete studies.

7. OPTIMUM PERFORMANCE

• LR-D1 should not be applied when ambient, substrate and material temperatures are below 5 °C (40 °F) or above 35 °C (95 ° F).
• For adverse temperatures, follow ACI recommendations for Cold/Hot Weather Concreting.
• Performance of in-place shotcrete relies heavily upon application techniques. To ensure optimum quality of in-place shotcrete, the material, equipment and key personnel should be pre-qualified prior to project start-up.
• Special provisions are required when using LR-D1 in conjunction with galvanic anodes to ensure performance, please contact your local KING Technical Representative for more information.

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.
