Multi-Purpose, Non-Shrink, Contractor Grade ASTM C1107 Grout for Structural and Non-Structural Grouting

DESCRIPTION: CTS CONSTRUCTION GROUT is a versatile, non-shrink grout that can be mixed to any consistency from damp pack to fluid. CONSTRUCTION GROUT is a high quality blend of portland cement, non-shrink additives, and specialty sand. When mixed with water, CONSTRUCTION GROUT produces a durable, high strength material that can be used for grouting and general concrete applications on interior and exterior projects. The final color of CONSTRUCTION GROUT is gray.

USES: Use CONSTRUCTION GROUT for structural and non-structural applications, including precision grouting, base plates, precast components, machinery and equipment bases, anchor bolts, keyway joints, load bearing pads, and other non-shrink applications.

SURFACE PREPARATION: Concrete surfaces must be clean, sound, and free from any materials that may inhibit bond such as oil, dirt, asphalt, sealing compounds, acids, wax, and loose debris. When bonding is important, all surfaces must be mechanically abraded by scarifying, grinding, shot blasting, or other approved methods. Placement area must be between 45°F to 90°F (7°C to 32°C). Saturate the substrate with clean water for a minimum of 4 hours. Remove any standing water or puddles before placement of the material.

FORMS: Construct forms to be watertight and non-absorbent. Joints must be sealed with polyurethane foam, caulk, or putty. Forms must be coated or lined with bond breaker or form release. Provide adequate vent holes to avoid air entrapment. Construct a head placement at a 45 degree angle to facilitate the grout pour. Build forms 1" (2.5 cm) higher than the base of the plate and 1" to 3" (2.5 cm to 7.6 cm) between all sides of the plate and form.

MIXING: The use of a power-driven mechanical mixer, such as a mortar mixer or a drill-mounted mixer, is recommended. Add potable water, then add dry grout material while mixing. Adjust water temperature to ensure the mixed grout is between 45°F and 90°F (7°C and 32°C). Mix for a minimum of 4 to 5 minutes. Working time is approximately 15-20 minutes.

Consistency of the grout is dependent on jobsite variables such as ambient temperature, water temperature, product temperature, and mixing method.

Use the following mix water guidelines:

Plastic consistency

– 3.5 quarts (3.3 L)

Flowable consistency

– 4.0 quarts (3.8 L)

Fluid consistency

– 5.5 quarts (5.2 L)

Adjust the water to achieve the desired flow consistency. Do not exceed 5.5 quarts (5.2 L) of water per 50-lb (22.7-kg) bag. Adding too much water may induce bleeding and segregation. Fluid consistency is achieved when the material flows through the flow cone in 25 to 35 seconds per ASTM C939.

For deep pours over 2" (5.1 cm), extension is required. Add up to 25 lbs (11.3 kg) of clean, dry 3/8" (0.95 cm) pea gravel per 50-lb (22.7-kg) bag. Do not exceed an 8" (20.3 cm) slump (ASTM C143) to prevent segregation. This may require less than the stated maximum [5.5 quarts (5.2 L)] water dosage. Do not add any additional dry materials such as cement, sand, additives or admixtures.

PLACEMENT: Place grout continuously into forms in one placement. CTS CONSTRUCTION GROUT may be placed by pump. All machinery near grout placement must be shut down for 24 hours. Limit the amount of vibration during grout placement to reduce potential segregation. CONSTRUCTION GROUT must fill all areas and stay in contact with load bearing area. Remove forms once grout has achieved final set.

CURE: Use a curing compound in accordance with ASTM C309 upon final set or wet cure with clean potable water on open surfaces for three days.

YIELD & PACKAGING: CONSTRUCTION GROUT is available in 50-lb (22.7-kg) bags. One 50-lb (22.7-kg) bag will yield 0.38 ft3 (0.01 m3) at a flowable grout consistency. Coverage may vary due to jobsite conditions.

TEMPERATURE: CONSTRUCTION GROUT may be applied in temperatures ranging from 45°F to 90°F (7°C to 32°C).

SHELF LIFE: CONSTRUCTION GROUT has a shelf life of 12 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged package.

USER RESPONSIBILITY: Before using CTS products, read current technical data sheets, bulletins, product labels and safety data sheets at www.CTScement.com. It is the user’s responsibility to review instructions and warnings for any CTS products prior to use.

WARNING: DO NOT BREATHE DUST. AVOID CONTACT WITH SKIN AND EYES. Use material in well-ventilated areas only. Exposure to cement dust may irritate eyes, nose, throat, and the upper respiratory system/lungs. Silica exposure by inhalation may result in the development of lung injuries and pulmonary diseases, including silicosis and lung cancer. Seek medical treatment if you experience difficulty breathing while using this product. The use of a NIOSH/MSHA-approved respirator (P-, N- or R-95) is recommended to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid ingesting cement dust. Skin contact with dry material or wet mixtures may result in bodily injury ranging from moderate irritation and thickening/cracking of skin to severe skin damage from chemical burns. If irritation or burning occurs, seek medical treatment. Protect eyes with goggles or safety glasses with side shields. Cover skin with protective clothing. Use chemical resistant gloves and waterproof boots. In case of skin contact with cement dust, immediately wash off dust with soap and water to avoid skin damage. In case of skin contact with wet cement, wash exposed skin areas with cold running water as soon as possible. In case of eye contact with cement dust, flush immediately and repeatedly with clean water, and consult a physician. If wet cement splashes into eyes, rinse eyes with clean water for at least 15 minutes and go to the hospital for further treatment.
