803 CONSTRUCTION GROUT – SR
803 CONSTRUCTION GROUT – SR is a pre-blended Portland cement grout containing non-ferrous admixtures to counteract plastic and drying shrinkage. The product complies fully with ASTM C827 test specifications for non-shrink grout. 803 CONSTRUCTION GROUT – SR is formulated using admixtures recommended for non-shrink grout by the U.S. Corps of Engineers and American Concrete Institute publications. There are no corrosive or unstable ingredients in 803 CONSTRUCTION GROUT – SR.
803 CONSTRUCTION GROUT – SR is ideal for every phase of structural grouting, including structural members, bridge seats, machinery bases, crane rails, anchorage systems, underpinning, and concrete repairs. The product is Ideal for use where a sulfate-resistant grout is required.
- Very versatile in use.
- May be pumped, packed, or poured.
- Ambient temperatures during placing may vary from 4° to over 30°
- At normal temperatures the working time or pot life is one full hour, which allows ample time for mixing, transporting, and placing.
- Other than conventional concrete curing requirements, no other special measures are necessary to preserve the stability of 803 CONSTRUCTION GROUT – SR.
25 Kg Bags
One bag (25 kg) will yield approximately 14,200 cm³ (1.5 ft.³). For exceptionally thick sections, [10 cm (4″) and over] 803 CONSTRUCTION GROUT – SR should be cut 50% with pea gravel or 9.5 cm (3/8″) crushed stone.
One year from date of manufacture when stored indoors on pallets in a dry, cool area. Do not store product outside.

|Colour||Slightly darker than normal concrete|
|Pot Life||1 hour @ 15° – 21° C|
|Set Time||Flowable mix 5 – 6 hours @ 21° C|
|Compressive Strength||52 MPa (7500 psi) in 28 days|
Compressive strength will vary with the amount of mixing water used and with ambient temperatures during curing. Specimens for compressive strength should be taken in 25.4 mm (2″) brass cube moulds under total confinement and according to CRD-C 621 procedures. The chart below indicates the typical pattern for flowable consistencies and cured at room temperature. Less flowable consistencies will exhibit high strengths.
30 – 45 seconds through flow cone
Approximately 4.5 litres of water per 25 kg bag.
Zero slump consistency
Approximately 3.5 litres of water per 25 kg bag
Surface Preparation … Foundation concrete to receive grout must be roughened, cleaned of all foreign matter and laitance, and thoroughly water saturated. All freestanding water should be blown clear just prior to placing grout.
Application Method … The mix should contain only enough water to form a cohesive ball when squeezed tightly in the hand. Mixing should be done by hand using a shovel and wheelbarrow or mortar box. Water should be sprinkled over the dry material and turned into the mix thoroughly using a shovel. See water mix rations above. The mixed grout must be rammed in place with a metal or hardwood tool. Discard mixed grout not rammed in place within one hour of initial preparation.
Extending … For exceptionally thick sections [4″ (101.6 mm) and over], 803 CONSTRUCTION GROUT – SR should be cut 50% with pea gravel or 9.5 mm (3/8″) crushed stone.
Curing … Cure 803 CONSTRUCTION GROUT – SR immediately following application using a suitable curing compound from W. R. MEADOWS, or in accordance with ACI 308. 1100, 1220-WHITE, CS-309™ series, or VOCOMP®-25 from W. R. MEADOWS are recommended. When conditions exist for rapid early water loss, the use of EVAPRE™, an evaporation retarder from W. R. MEADOWS, is also recommended.
Compressive strength will vary with the amount of mixing water used and with ambient temperatures during curing. Specimens for compressive strength should be taken in 50.8 mm (2″) brass cube molds under total confinement and according to CRD-C 621 procedures. Less flowable consistencies will exhibit high strengths. Ambient temperatures during placing may vary from 4° C to over 30° C. At normal temperatures the working time or pot life is one full hour. Slightly accelerated or retarded working time will apply when working in hot or cool conditions respectively. Moderate vibration and agitation of the fresh grout is permitted.
