588-10K
Non-Shrink, Non-Ferrous, Mineral-Aggregate-Based Precision Grout

DESCRIPTION
588-10K is a hydraulic-cement-based, precision, non-shrink, load-bearing grout designed to transfer load effectively and safely, ensuring long service time of the grouted item. It is a non-corrosive, non-metallic, mineral-based precision grout, developed to have high initial and ultimate flexural and compressive strengths. It can be mixed quickly, as needed, on the jobsite. 588-10K offers exceptional workability and is easily placed by pouring or pumping. The product is designed to give non-shrink performance under various conditions for both interior and exterior applications.

USES
588-10K is designed for precision grouting of machinery and equipment base plates, windmill turbines, generators, rolling mills, compressors, or similar types of machinery. 588-10K is also designed for grouting soleplates, bridge seats, precast columns and beams, steel column pads, precast beams, and segmental bridge construction. 588-10K can also be used for anchoring of guardrails, signposts, bridge seats, anchor bolts, guide wires, and dowels.

PACKAGING
50 lb. (22.7 kg) Poly-Lined bags.

SHELF LIFE
Twelve months when stored indoors on pallets in a dry, cool area. Do not store product outside.

YIELD
Each 50 lb. (22.7 kg) bag yields 0.43 to 0.64 ft.³ (0.0122 m³) of in-place grout using the median water ratio level, dependent upon rate of extension.

APPLICATION
Grouting application shall be performed in accordance to American Concrete Institute (ACI) 351.1R: Grouting Between Foundations and Bases for Support of Equipment and Machinery and other applicable industry standard practices.

Surface Preparation … All grout contact surfaces must be free of oil, grease, scale, penetrating sealers, or all other types of contaminates that will interfere with the bond. Mechanically roughen or high pressure water-jet the existing concrete substrate. Surface must be rough and profiled, but generally level. Grouting area must be saturated with water 12 - 24 hours prior to grouting. Remove all excess water before placing grout.

Forming … Forming method must provide for rapid, continuous grout placement. For pouring, allow a minimum clearance of 3" for entry and 6" minimum grout "head.” Forming must also provide for venting to avoid entrapment of air. Provide 1/2" minimum form clearance on all sides and 1" clearance for head. Ensure form is well sealed and an appropriate form release agent has been applied for that type of form.

Mixing … Small quantities of 588-10K may be hand-mixed in a concrete mixing pan until lump-free. For large quantities and continuous pours, mix using a mortar mixer with rubber-tipped blades or appropriate grout pump for a minimum of three minutes or until lump-free and uniform. Use the minimum water required to produce desired placement consistency. Use 6.5 pts. (3.1 L) of water per bag for plastic consistency; 7.25 pts. (3.4 L) for medium flow (pourable), and 8.25 pts. (3.9 L) for high flow. Mix in two steps: add 2/3 of water requirement, then add grout. After partial mixing, add remainder of water for desired consistency. Thoroughly mix total quantity for 2 - 3 minutes. Do not mix more than can be placed in 15 minutes at 75° F (23° C). Do not retemper.

Placement …588-10K is easily placed by pouring or pumping and compaction can be accomplished by rodding or tapping. Place grout on one side, flowing to opposite and adjacent sides, to avoid entrapment of air. When necessary, provide vent holes. Grout head and excess grout may be removed after initial set. W R. MEADOWS recommends the Machine Technologies P-25 mortar pump and D-25 continuous mixer for pumping applications. For more information, visit www.machinetechnologies.com.

Curing … Immediately following application, cure 588-10K using a suitable curing compound from W. R. MEADOWS, or in accordance with ACI 308. 2200-WHITE series or 1100-CLEAR series from W. R. MEADOWS is recommended. When conditions exist for rapid early water loss, the use of EVAPRE™ from W. R. MEADOWS is also recommended.

PRECAUTIONS
Do not use as a repair mortar. (Please contact W. R. MEADOWS for specific repair mortar recommendations.) Do not pre-mix in a ready-mix truck, either at batching plant or onsite.
