S5Z WIL-X CEMENT GROUT

Conforms to ASTM C845 Type K

Wil-X is chemically compensated for shrinkage. It has a high bond value and is crack resistant for permanent installations. Wil-X can be used safely with most concrete admixtures. Wil-X grout will be thicker than a Portland cement grout with the same water to cement ratio. Therefore, use of a high-range water reducing admixture (super plasticizer) is recommended if grout will be pumped or if higher fluidity is desired. Because it is a cement-based grout, it is non-explosive and has a six-month shelf life when stored properly in a dry location and out of direct sunlight.

Wil-X may be used to build up leveling pads by simply mixing with sand or pea gravel. This mixture should not be run through the grout pump.

Setting Time: Gilmore Needles (ASTM C266). Initial set 45 minutes; final set 10 hours.

US Spec RA Grout

Product Description

US Spec RA Grout consists of specialty blended cements and admixtures to provide maximum flow, shrinkage compensation and extended working times in an aggregate free formulation where clearances are minimal. RA Grout is non-metallic and non-corrosive. RA Grout has been specifically formulated to meet and exceed the testing requirements of ASTM C-1107 and US Army Corps of Engineers CRD C-621. When tested in accordance with ASTM C-827 RA Grout yields a controlled positive expansion.

Advantages
  • Pumpable fluid grout for very tight clearances
  • Non-bleeding
  • Attains high compressive strengths at specified w/c ratios
  • Extended working time for maximum pumping range
  • Non-shrink from time of placement
  • Thixotropic: High flow restored by agitation
  • Encapsulates tendons, bolts or bars to protect from corrosion
  • Consistent: Strict Quality Control testing and standards

 

Time PSI MPa
1 Day 4,500 31.02
7 Days 9,000 62.05
28 Days 12,000 82.73

 

Packaging and Yield

US Spec RA Grout is packaged in heavy duty, polyethylene line backs containing 50 lb (22.7 kg), yielding 0.53 cubic feet when 7.75 quarts of mixing water is used. Each pallet contains 48 bags of RA Grout.

Mixing

Mix US Spec RA Grout to a uniform consistency in accordance with the manufacturer’s instructions. Potable water containing no chlorides or other foreign substance shall be used. The water shall be accurately measured and placed in the mixer first. Start with 1.94 gallons of water per 50lb bag of US Spec RA Grout and mix continuously for 3-5 minutes before placing. If possible, the grout should be mixed continuously until placing is completed, but if this is not practical, a brief remixing prior to pumping or placement is adequate to overcome the effect of “thixotropic set”. Do not use any other admixtures or additives.

Note: Results based on a controlled laboratory environment (see product data for details). Jobsite results may vary.

Post-Grout Tube

Williams will provide post-grout tubes for anchors bonded in weak rock or soil upon request. The Williams supplied flexible or rigid post-grout tube has a bursting strength of 1000 psi. The post-grout tube length and valve placement are adjustable and can be specified at the time of order. There is no field assembly of the post grout tube, other than attaching it to the anchor as it is being installed down the drill hole. Drill hole diameter should be a 1” minimum clearance to accommodate Post-Grout Tube.

Grout Saddle with Valve

For quick attachment and release of tendons to grout hose.

T4Z Grout Tube Adapter

For down pressure grouting only when grout is forced through normal grout hole in the hollow rebar

Grout Socks

What was once considered to be an impossible anchorage is made easy with a practical solution from Williams. For difficult bonding applications such as anchors in weak coral, sandstone, highly fractured rock, underwater holes and in artesian water conditions, we place Grout Socks on our grout bonded anchors to prevent grout loss due to permeation or washing away by flowing water. The socks are individually manufactured to be a minimum of 1” larger than the drill hole diameter, allowing the sock to expand into the deformations in the drill hole wall, and in many cases providing the only means to achieve a mechanical bond. In some geotechnical conditions, designers should be aware that Grout Sock may adversely affect the bond strength between the grout and ground. Williams recommends that a testing program be implemented to determine actual bond stress values for elements installed with grout socks.

Super Plasticizer

Plasticizer is available and is used as a water reducer for ease of pumping grout through tubes at lower water to cement ratios.
