DESCRIPTION
588 is a Portland cement based precision grout. It is
non-corrosive, non-gaseous and provides high density,
high initial and ultimate flexural and compressive
strengths. It can be mixed quickly, as needed, on the
jobsite. 588 offers exceptional workability and is easily
placed by pouring or pumping. The product is designed
to give non-shrink performance under various
conditions, in interior or exterior applications.
USES
588 is suggested for precision grouting of machinery
bases, generators, rolling mills, punch presses,
compressors, etc.; structural grouting of precast
columns, steel columns, crane rails, precast beams, etc.;
anchoring of guard rails, sign posts, bridge seats,
anchor bolts, guide wires, dowels, etc.

PACKAGING
50 lb. (22.7 kg) poly-lined bags.
SPECIFICATIONS
Corps of Engineers Specification: CRD-C 621
USDA Accepted
ASTM C 1107, Grades A, B & C
YIELD
Each 50 lb. (22.7 kg) bag yields 0.43 to 0.64 cubic feet
(0.0122 cubic meters) of in-place grout using the
median water ratio level, dependent upon rate of extensions.
APPLICATION
All grouting should be done using established
procedures according to American Concrete Institute
recommendations: ACI 351.1R-93 "Grouting for
Support of Equipment and Machinery."
Surface Preparation … All grout surfaces must be clean and completely free of laitance, oil, grease, other coatings and any other contamination. Unsound concrete must be chipped out, leaving surface level, but rough. Grout area should be saturated with water 12-24 hours prior to grouting. Remove all excess water before placing grout. Surface should be saturated, surface dry (SSD).
Forming … Method of forming must provide for rapid, continuous grout replacement. 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."
Mixing … Small quantities of 588 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 uniformed and until lump-free. Use minimum water required to produce desired placement consistency. Use 6.5 pts. (3.1 liters) of water per bag of grout for plastic consistency; 7.25 pts. (3.4 liters) for medium flow (pourable) and 8.25 pts. (3.9 liters) for high flow. Mix in two steps: Add 2/3 of water requirement ... 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 30 minutes.
Placement … 588 can be easily placed by pouring or pumping; compaction can be accomplished by rodding or light vibrating. 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.
Curing … 588 should be cured in accordance with ACI 308. If a membrane curing compound is used, we suggest using CS-309™-25 or VOCOMP®-25 curing and sealing compounds from W. R. MEADOWS.
Cost reductions are realized by extending with clean, 3/8" (9.5 mm) pea gravel. In applications where grout thickness is to be 2" to 4" (50 to 100 mm), up to 25% of aggregate, based on weight of grout, may be added. For thicknesses over 4" (100 mm), up to 50% of aggregate may be added. Such additions may be made to the flowable mix.
PRECAUTIONS
Do not use as a repair mortar. (Please contact
W. R. MEADOWS for specific repair mortar
recommendations.) Read and follow application
information and precautions. Refer to Material
Safety Data Sheet for complete health and safety
information.
