SPEED-E-ROC™

Rapid-Setting Anchoring Cement Grout

DESCRIPTION
SPEED-E-ROC is a pourable, rapid setting and hardening, high strength, hydraulic cement compound designed for anchoring and grouting. SPEED-E-ROC has a controlled expansion system and is non-shrink. SPEED-E-ROC has an initial set time of 10-20 minutes at 77° F (25° C) and obtains 5,000 psi (34.4 Mpa) in one hour.

USES
SPEED-E-ROC is ideally suited for anchoring rails, bolts, ties, dowels, reinforcing steel, threaded rods, sign posts, parking meters, street signs and ornamental steel work into concrete or any other properly-prepared, porous, hardened material. SPEED-E-ROC may be used as a precision, highly flowable and rapid-setting grout for machinery base plates, bearing plates and columns. It is suitable for industrial, residential and civil engineering applications. The product can be used in either interior or exterior applications, freeze-thaw and wet environments.

FEATURES/BENEFITS

• Very rapid hardening and setting properties.
• Suitable for exterior and interior applications.
• Freeze-thaw stable; may be used in wet environments.
• Very high one hour and 24-hour strengths .
• Controlled expansion.
• Cement-based; contains no chloride accelerators.
• Friendly grayish appearance.
• Non-metallic and contains no chlorides.
• Easy to use; just mix with water.
• Very pourable.
• Accelerates Portland cement based materials.

TECHNICAL DATA*

Set Time (Per ASTM C 191)	10 - 20 Mins.
Controlled Expansion	0.15%
Compressive Strength (Per ASTM C 109-air cured) @ 1-hour 5,000 psi (34.5 Mpa) @ 24 hours 7,000 psi (48.3 Mpa) @ 28 days 11,500 psi (79.3 Mpa)
* All technical data is typical information, but may vary due to testing methods, conditions and operators.

SHELF LIFE
Twelve months when stored in an unopened container in a dry, cool area

PACKAGING AND YIELD
50 lb. (22.7 kg) pail yields: 0.50 ft.³ (14.1 L)
8 lb. (3.6 kg) tub yields: 0.08 ft.³ (2.26 L)

Yields listed above are based on 8 pints (3.8 L) of water per 50 lb. (22.7 kg) pail of SPEED-E-ROC and will vary based on substrate profile, variations in mix water amounts and waste. Field trails should be preformed to determine yields based on job-site conditions.

FOR BEST PERFORMANCE

• Not intended to be used as an underlayment or overlay.
• Do not apply below 35° F (1.7° C) or above 95° F (35° C) or when rain is imminent.
• Protect from freezing for a minimum 24 hours. SPEED-E-ROC should be crowned or shaped as to allow water flow away from anchor and/or coated with a concrete sealer or penetrating sealer.
• Do not add any admixtures.
• Exceeding liquid requirements shall result in reduced physical properties.
• Realize that set time will decrease as the product, air, substrate and mixing liquid temperature increases and will be increased as the temperature decreases.
• Failure to follow industry standard practices may result in decreased material performance.
• Proper application is the responsibility of the user. Field visits by W. R. MEADOWS personnel are for the purpose of making technical recommendations only, and are not to supervise or provide quality control on the jobsite.

SURFACE PREPARATION for Anchoring into Concrete or Porous Hardened Material
Substrate must be structurally sound and free of any contaminants that will adversely affect bond. Drill anchor hole using a rotary percussion hammer. Prepared surface must be dust-free and have a sufficient profile to ensure adequate mechanical lock.

Presoak repair zone, prior to application of SPEED-E-ROC, to a saturated, surface dry (SSD) condition and free of standing water.

Anchor bolts must be installed utilizing a washer. The anchor hole diameter shall be no larger than what is required for the anchor bolt and washer assembly to slide to the bottom of anchor hole and rest on bolt head.

Grouting
Substrate must be structurally sound and free of any contaminants that will adversely affect bond. Prepared surface must be dust-free and have a sufficient profile to ensure adequate mechanical lock. Presoak repair zone prior to application of SPEED-E-ROC to a saturated, surface dry (SSD) condition and free of standing water. Ensure forming system is watertight to avoid excessive leakage of SPEED-E-ROC from the grout zone. Use a suitable release agent such as DUOGARD® from W. R. MEADOWS, on forms to aid in the removal process.

Mixing
Mix one part potable water to six parts of SPEED-E-ROC or until homogeneous and lump-free, pourable mixture is obtained.
Mix 50 lb. (22.7 kg) pail with approximately eight pints (3.8 L) of potable water.
Mix 8 lb. (3.6 kg) tub with approximately 1.25 pints (0.6 L) of potable water.

SAFETY AND TOXICITY
Avoid inhalation of dust. Avoid direct contact with this product. Utilize gloves and safety glasses to minimize direct contact. If contact occurs, wash affected areas with mild soap and water. Keep product out of reach of children. For industrial use only. Refer to Material Safety Data Sheet for complete health and safety information.
