3. USES

• Ground support applications for mining, tunneling and other underground openings.
• Rehabilitation of marine structures.
• Lining and rehabilitation of sewers and other tunnels.
• Slope stabilization, soil-nailing, shaft and tunnel linings.
• Use of a predampener in conjunction with dry-process, accelerated shotcrete is not recommended. Contact your local KING Technical Representative for more information.

4. PROCEDURES

Surface Preparation (Rock Surfaces): All surfaces to be in contact with MS-D1 ST 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 MS-D1 ST 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 MS-D1 ST in accordance with the ACI 506 “Guide to Shotcrete” publication.

5. CURING

Good curing conditions are beneficial to optimizing physical properties of MS-D1 ST. Although the high relative humidity commonly found in underground environments provides for good curing conditions, additional curing is often appropriate and should be performed in accordance with ACI 308 “Guide to Curing Concrete”.

For rehabilitation applications, shotcrete 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.

7. OPTIMUM PERFORMANCE

• MS-D1 ST should not be applied when ambient, substrate and material temperatures are below 5 °C (40 °F) or above 35 °C (95 °F).
• 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.
• Recommended minimum inside diameter of shotcrete hoses should be 50 mm (2 inches).

8. YIELD

1,000 KG (2,205 lb) bag contains approximately 0.45 m3 (16.5 ft3).

9. PACKAGING

MS-D1 ST is normally packaged in 1000 KG (2205 lb) bulk bags and polywrapped on wooden pallets. All KING products can be custom packaged to suit specific job requirements.

10. STORAGE AND SHELF LIFE

Material should be stored in a dry, covered area, protected from the elements. Unopened bags have a shelf life of 12 months. Physical properties of MS-D1 ST may be adversely affected if material is stored in temperatures below 0 °C (32 °F). Material store below these temperatures should be allowed to warm to ambient underground temperatures before shooting.

11. SAFETY PROCEDURES

MS-D1 ST contains Portland cement. Normal safety-wear such as rubber gloves, dust mask and safety glasses used to handle conventional cement based products should be worn. Safety Data Sheets are available upon request.

SECTION 2: HAZARDS IDENTIFICATION

Potential Health Effects

Route of Exposure Inhalation; ingestion; skin contact; eye contact.
Inhalation Exposure to airborne concentrations above exposure limits may cause irritation of the nose, throat and lungs.
Skin Contact May cause dry skin, discomfort and irritation. Repeated or prolonged exposure can irritate or burn the skin.
Eye Contact Airborne dust may cause immediate or delayed irritation or inflammation. Contact causes severe burns with redness, swelling, pain and blurred vision. Permanent damage including blindness can result.
Effects of Long-Term (Chronic) Exposure Risk of injury depends on duration and level of exposure. This product contains crystalline silica. Prolonged or repeated inhalation of the respirable crystalline silica can cause silicosis, a seriously disabling and potentially fatal lung disease. See Section 4 for further information.
Carcinogenicity CARCINOGEN. Known to cause: lung cancer.

Notes:  Other additives not controlled through WHMIS or other legislation.

SECTION 4: FIRST AID MEASURES

First Aid Procedures

Inhalation Move victim to fresh air. Seek medical attention for discomfort or if coughing or other symptoms do not subside.
Skin Contact Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes.
Eye Contact Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
Ingestion NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. DO NOT INDUCE VOMITING. If conscious, give victim a glass of water or milk. Immediately call a Poison Centre or doctor.

 

Note to Physicians
Additional Notes – Silicosis – There are three (3) types of silicosis:

1) Simple chronic silicosis – which results from long-term exposure (more than 20 years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirable crystalline silica form in the lungs and chest lymph nodes. This disease may feature breathlessness and may resemble chronic obstructive pulmonary disease (COPD).

2) Accelerated silicosis – occurs after exposure to larger amounts of respirable crystalline silica over a shorter period of time (5-15 years). Inflammation, scarring, and symptoms progress faster in accelerated silicosis than in simple silicosis.

3) Acute silicosis – results from short-term exposure to very large amounts of respirable crystalline silica. The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood oxygen levels.

Progressive massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive fibrosis results from severe scarring and leads to the destruction of normal lung structures.

SECTION 5: FIRE FIGHTING MEASURES

Flammable Properties Does not burn.
Suitable Extinguishing Media Not combustible. Use extinguishing agent suitable for surrounding fire.
Specific Hazards None known.
Arising from the Chemical
Protective Equipment and Precautions for Firefighters Quartz is a carcinogen and chronic inhalation hazard. Firefighters may enter the area if positive pressure self-contained breathing apparatus (NIOSH approved or equivalent) and full Bunker Gear is worn. Wash down contaminated Bunker gear with water to remove any quartz fibres

SECTION 6: ACCIDENTAL RELEASE MEASURES

Personal Precautions Use the Personal Protective Equipment recommended in Section 8 of this MSDS. Restrict access to area until completion of clean up. Ensure clean-up is conducted by trained personnel wearing appropriate respiratory protection and chemical protective clothing.
Environmental Precautions Do not allow into any sewer, on the ground or into any waterway.
Methods for Containment and Clean-up Avoid dry sweeping. If necessary, use a dust suppressant such as  water. Do not use compressed air for clean-up. Allow material to dry or solidify before disposal. Collect using shovel/scoop or approved HEPA vacuum and place in a suitable container for disposal. Dike and recover contaminated water for appropriate disposal. Flush area with water.

 

SECTION 7: HANDLING AND STORAGE

Handling Only use where there is adequate ventilation. Avoid generating dusts. Good housekeeping is extremely important. Prevent dust accumulation on ALL surfaces including ceiling rafters and other hidden surfaces. Bagged product is heavy and poses risks such as sprains and strains to the back, the arms, the shoulders and the legs during lifting and mixing.
Storage Store in an area that is: dry. Store in the original, labelled, shipping container. Prevent dust build-up on ALL surfaces. Clean frequently. Avoid dry-sweeping. Use vacuum cleaner equipped with high efficiency filter. Keep away from food and drinking water.
