Cementitous Grouts - SikaGrout®-528 SF

High performance, cementitious grout with bleed resistance

Non-shrink, non-metallic, cementitious grout with a unique two-stage shrinkage compensating mechanism. With a special blend of shrinkage-reducing and plasticizing/water-reducing agents, SikaGrout®-528 SF compensates for shrinkage in both the plastic and hardened states.

• Does not contain aluminum powder nor any components which generate hydrogen gas, carbon dioxide or oxygen.
• Enhanced with un-densified silica fume for low permeability
• Non-metallic, will not stain or rust
• Bleed resistant, even at high flow
• Low heat build-up
• Non-corrosive

Usage

• Use to grout and fill or repair voids in concrete
• Use for grouting tight clearances

Application Steps

• For best results use a colloidal mixer similar to ChemGrout© CG-600 series or other type of high shear mixer at approximately 1,800 rpm.
• Start by using 11.5 pints (5.4 L) of water at approximately 70°F (If higher, use cold water; if colder, use warm water.) per bag in a clean and appropriate mixing vessel.
• Add bag of material to mixing vessel.
• Mix for minimum of 3 minutes after the addition of the last bag or until a homogeneous mix is achieved.
• Continue to agitate material in the holding hopper to achieve best flow.
• Only add additional water as needed up to a total maximum of 12.5 pints (5.9 L) (DO NOT EXCEED) per bag in order to achieve the flow specified on the Product Data Sheet (PDS).
• At higher temperatures and/or water amounts near upper range of maximum 12.5 pints (5.9 L), the grout will be less thixotropic. Therefore, it may be more appropriate to measure the flow using the standard flow cone test (ASTM C-939).

• Alternatively, for quantities less than 1 bag, mechanically mix with high-speed drill (2,500 rpm) and Sika jiffy paddle for a minimum of 6 minutes.
• Method of mixing may significantly affect the material properties, particularly flow.

• Project specific testing by the engineer is recommended to ensure that the mixing and placement methods result in the specified requirements.

• Make sure all forming, mixing, placing, and clean-up materials are on hand.
• A mock-up should be completed on-site and inspected by the engineer to ensure that the placement means and methods yield the specified results.
