PT



PT is a neat, high performance, shrinkage-compensated, post-tensioning grout. It is an unsanded, Portland cement-based, expanding shrinkage-compensated, post-tensioning grout containing silica fume and other carefully selected components. It is pumpable and has enhanced flowability making it ideal for grouting post-tensioning cables, tendons and other highly stressed steel cable applications.

• Superior early strength gain, allowing early tensioning of anchors
• Very fluid, easily pumpable, and exhibits little or no bleeding even when pumped under pressure
• Excellent cohesive properties
• Net positive displacement (expansion) ensures maximum bond and protects against future water ingress
• Provides protection against corrosion
• Improved resistance to sulphate attack


1. FEATURES & BENEFITS

• Superior early strength gain, allowing early tensioning of anchors
• Very fluid, easily pumpable, and exhibits little or no bleeding even when pumped under pressure
• Excellent cohesive properties
• Net positive displacement (expansion) ensures maximum bond and protects against future water ingress
• Provides protection against corrosion
• Improved resistance to sulphate attack
• Very low permeability
• All KING products are manufactured using ISO 9001:2008 Certified Processes

2. USES

• Grouting pre-tensioned or post-tensioned cables or rods
• For most other grouted anchor requirements including cable bolting, earth tie-backs for excavation or soil stabilization, grouting anchors in tunnel support systems, re-bar grouting and grouting soil or rock tendons for anchoring piles or foundation structures
• Infill of pipe piles

3. PROCEDURES

Surface Preparation: All ducts, vents, inlets and outlets should be checked for obstruction by blowing dry, oil-free, compressed air through each duct prior to grouting.

Mixing: A high-speed colloidal mixer equipped with a calibrated measuring device for determining the quantity of water, shall be used. Introduce potable water (see below) into mixer and then add PT while operating at medium speed. The maximum recommended volume of water for a pumpable consistency is 10.0 L (2.64 US gallons) per 30 KG (66 lb) bag. Mix at high speed for a minimum of one minute. The time between mixing and pumping of the batch should not exceed 15 minutes.

5. OPTIMUM PERFORMANCE

• Adhere to recommended water additions. Exceeding the maximum recommended water:material ratio will result in reduced compressive strengths and inferior physical properties.
• Surface temperature of the grouted area should be between 5 °C (40 °F) and 35 °C (95 °F)
• Do not use PT if water/material temperature results in a flow of greater than 25 seconds

6. YIELD

30 KG (66 lb) bag contains approximately 0.020 m3 (0.7 ft3).

7. PACKAGING

PT is packaged in 30 KG (66 lb) triple-lined bags and polywrapped on wooden pallets. All KING products can be custom packaged to suit specific job requirements.

8. STORAGE AND SHELF LIFE

Material should be stored in a dry, covered area, protected from the elements. Unopened bags have a shelf life of 3 months.

9. SAFETY PROCEDURES

PT 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; skin contact; eye contact; ingestion.
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.
Eye Contact Airborne dust may cause immediate or delayed irritation or inflammation.
Effects of Long-Term (Chronic) Exposure Risk of injury depends on duration and level of exposure.

SECTION 3: COMPOSITION/INFORMATION ON INGREDIENTS

Chemical Name CAS Registry No. Concentration % Other Identifiers
Portland cement 65997-15-1 60-100%
Silica fume 69012-64-2 5-10%

 

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 Seek medical attention for rash, burns, irritation, dermatitis and prolongedunprotected exposures to wet cement, cement mixtures or liquids from wet cement.
Eye Contact Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open.
Ingestion NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. DO NOT INDUCE VOMITING. 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.

TLV® = Threshold Limit Value. TWA = Time-Weighted Average. A2 = Suspected human carcinogen. R = Respirable fraction.
Engineering Controls If user operations generate dust, fume, or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
Personal Protective Equipment (PPE)
Eye/Face Protection Approved safety eye wear should be worn, based on the risk assessments performed.
Skin Protection Personal protective equipment for the body should be selected based on the task being performed. This includes gloves, coveralls and footwear. Approved gloves should be worn based on risk assessments.
Respiratory Protection Use of an approved respirator, based on a risk assessment is necessary. Respiratory protection should be selected based on the known or anticipated levels of exposure, and the work being performed.
