RB-RG High strength, non-shrink cementitious construction grout
RB-RG is a ready to use product in powder form, which requires only the on-site addition of water to produce a non-shrink grout of predictable performance.
- RB-RG is formulated for use at plastic or flowable consistency, and may be used with confidence for bedding, grouting and void filling operations
Features and benefits :
- Early strength development even at flowable consistency
- High bond strength to steel and concrete
- Proven and predictable performance
- Adjustable consistency
- Non shrink
How to use :
The surface onto which the grout is to be applied should be scabbled to remove laitance and expose aggregate. Do not use bush hammers or similar preparation equipment that can crush the aggregate but leave it in place. The surface must be free of oil, dust, dirt, paint, curing compounds or other contaminants that could impair adhesion. Soak area to be grouted to minimise absorption. Surfaces should be damp but free of standing water. Particular attention should be paid to bolt holes to ensure that these are water-free. Use oil free compressed air to blow out bolt holes and pockets as necessary.
Base plates, bolts, etc. must be clean and free of oil, grease and paint. Set and align equipment. If shims are to be removed after the grout has set, then lightly grease them for easy removal.
Ensure formwork is secure and watertight to prevent movement and leaking during the placing and curing of the grout.
Damp down the inside of the grout mixer with water prior to mixing the initial batch of RB-RG. Ensure the mixer is damp but free of standing water. Add the pre-measured quantity of water. Slowly add the RB-RG, mixing continuously. Mix for 3-5 minutes until a smooth, uniform, lump free consistency is achieved.
Place immediately after mixing, into the prepared area in such a manner that the grout has the shortest distance to flow. Pour the grout continuously maintaining a constant hydrostatic head wherever possible. RB-RG grouts are suitable for use with most types of pumping equipment. Immediately after RB-RG grout is placed, cover all exposed grout with clean wet hessian and keep moist until grout surface is ready to be finished, or until final set.
