SikaQuick® 1000
Rapid hardening repair mortar with extended working time

Description

SikaQuick® 1000 is a 1-component, rapid hardening, early strength gaining, ementitious, patching material for concrete.

Where to Use

  • Use on grade, above, and below grade on concrete.
  • Highway overlays and repairs.
  • Structural repair material for concrete roadways, parking structures, bridges, dams and ramps.
  • Full depth patching repairs.
  • Economical patching material for horizontal repairs of concrete and mortar.

Advantages

  • Specially suited for hot weather applications when extended working time is required.
  • Rapid hardening as defined by ASTM C-928.
  • Epoxy coatings can be applied as early as 6 hrs. On site testing is recommended for verification. Please consult coatings manufacturer for recommendations.
  • Freeze/thaw resistant.
  • Easy to use, labor-saving material.
  • Not gypsum-based.
  • High early strength.
  • Open to foot traffic in 4 hours; to vehicle traffic in 6 hours (at 73°F).
  • Easily applied to clean, sound substrate.
  • Not a vapor barrier.

Coverage

Approximately 0.42 cu. ft. When extended with 25 lbs. of 3/8 in. gravel yield is approximately 0.58 cu. ft.

 

How to Use

Surface Preperation

Surface must be clean and sound. Remove all deteriorated concrete, dirt, oil, grease, and other bond-inhibiting materials from the area to be repaired. Be sure repair area is not less than 1/4 in. deep. Preparation work should be done by appropriate means. Obtain an exposed aggregate surface with a minimum surface profile of ± 1/8 in. (CSP-6) on clean, sound concrete. To ensure optimum repair results, the effectiveness of decontamination and preparation should be assessed by a pull-off test. Saw cutting of edges is preferred and a dovetail is recommended. Saturate surface to be repaired with clean water. Substrate should be saturated surface dry (SSD) prior to application.

Priming

For priming of reinforcing steel use Sika ® Armatec ® 110 EpoCem (consult Technical Data Sheet). Concrete Substrate: Prime the prepared substrate with a scrub coat of SikaQuick® 1000 prior to placement of the mortar. The repair mortar has to be applied into the wet scrub coat before it dries.

Mixing

Mechanically mix in an appropriately sized mortar mixer. Wet down all tools and mixer to be used. With water: Start with 4.5 pints of water added to the mixing vessel.

Add 1 bag of SikaQuick® 1000 while continuing to mix. Add up to another 1/2 pint of water to achieve desired consistency. Do not over-water.
With Latex R: Pour 4.5 pints of SikaLatex ® R into the mixing container. Slowly add powder, mix and adjust as above.
With diluted Latex R: SikaLatex ® R may be diluted up to 5:1 (water: SikaLatex ® R) for projects requiring minimal polymer modification. Pour 4.5 pints of the mixture into the mixing container. Slowly add powder, mix and adjust as above. For applica- tions greater than 1 in. in depth, add 3/8 in. coarse aggregate. The aggregate must be non-reactive (reference ASTM C-1260, C-227 and C-289), clean, well graded, saturated surface dry, have low absorption and high density, and comply with ASTM C-33 size number 8 per Table 2.
Note: Variances in aggregate may result in different strengths. The addition rate is 25 lbs. of aggregate per bag of SikaQuick® 1000. (25 lbs. of 3/8 in. aggregate is approximately 2.0 gallons by loose volume of aggregate). Do not exceed a slump of 7 in. This may cause excessive bleeding and retardation and will reduce the strength and performance of the material.

Application

The prepared mortar must be scrubbed into substrate. Be sure to fill all pores and voids. Force material against edge of repair, working toward center. After filling repair, screed off excess. Allow concrete to set to desired stiffness, then finish. If a smoother finish is desired, a magnesium float should be used. Mixing, placing, and finishing should not exceed 30 minutes maximum. To control setting times, cold water should be used in hot weather and hot water used in cold weather

Tooling & Finishing

As per ACI recommendations for portland cement concrete, curing is required. Moist cure with wet burlap and polyethylene,a fine mist of water or a curing compound meeting ASTM C-309. Moist cure should commence immediately after finishing. If necessary, protect newly applied material from rain. To prevent from freezing, cover with insulating material.

Limitations

  • Minimum ambient and surface temperatures 45°F and rising.
  • Minimum application thickness 1/4 in. as a mortar and 1 in. extended with aggregate.
  • Maximum application thickness 1 in. as a mortar and 6 in. extended with aggregate.
  • Do not feather edge.
  • Do not exceed 7 in. slump when extended.
  • Use only potable water.
  • Variations in aggregates may produce differences in strengths from the typical values stated in Sika's Technical Data.
  • As with all cement based materials, avoid contact with aluminum to prevent adverse chemical reaction and possible product failure. Insulate potential areas of contact by coating aluminum bars, rails, posts etc. with an appropriate epoxy such as Sikadur ® Hi-Mod 32.
  • Do not use Sika ® Armatec ® 110 EpoCem as a bonding agent with SikaQuick® 1000.
