Ronagrout GP

Shrinkage Compensated High Flow General Purpose Cement Grout

Ronagrout GP is a prepacked single component cementitious general purpose grout. Requiring only the measured addition of clean water to achieve workability from mortar consistency to free flowing grout. Ronagrout GP is suitable for various grouting, anchoring and concrete repair applications. The performance of the product is certified under the Hong Kong Concrete Institutes (HKCI) Product Conformity Certification Scheme for Repair Mortars (PCCS-RM) Class S and is suitable for repairs to concrete with a characteristic strength(fcu) up to at least 40 MPa. It can be applied in thick or thin section and is suitable for structural and non-structural repairs such as honeycombing ; Ronagrout GP contains an expansive agent to compensate for shrinkage and settlement in the plastic state and is specially modified to resist bleeding and segregation even when exposed to vibration. The rapid development of strength and high ultimate strength facilitates the early continuation of work and the installation of plant and equipment.  

  • Controlled expansion to compensate for shrinkage and settlement in plastic state
  • Can be used as a patching mortar or flowable grout
  • Application 10 mm up to 100 mm thick per layer (Maximum 25 mm overhead)
  • Easy to mix and apply
  • Rapid strength gain
  • Can achieve very high compressive, flexural and tensile strengths
  • Monolithic bond to substrate
  • Low VOC
  • Can contribute to LEED certification

Application steps

MIXING

A mechanical forced action mixer is required, specialist equipment is best but a heavy duty drill with a stirring type mixing blade should be suitable. Place the correct amount of water into the mixer and slowly add the entire 25 kg bag of Ronagrout GP whilst continuously mixing.

Ronagrout GP should be mixed for at least 5 minutes until a smooth and lump free consistency is achieved. Sika recommend high speed mixing followed by 1 minute of low speed mixing to ensure that all entrapped air is able to escape.

For trowel or patch repair application water addition should be in the range 3.6 to 5.0 L per 25 kg bag. For pourable application the water should be in the range 4.0 to 5.0 L per 25 kg bag. For free flow grouting applications the water addition should be 5.0 L per 25 kg bag.

For void free grouting the number of personnel and the capacity of the mixing equipment must be sufficient to enable grouting to be carried out in a single continuous operation.

 

APPLICATION

Ronagrout GP can be placed in thicknesses ranging from 10 mm to 100 mm in one single application. For application thicknesses over 100 mm Ronagrout GP can be extended with the addition of a clean, sound and well graded 5 mm to 10 mm aggregate. A maximum of 25 kg of aggregate per 25 kg of Ronagrout GP is recommended.

For vertical and overhead patch repair works Sika recommend keeping the water addition to a minimum and limiting layer thicknesses to 25 mm. Detailed information and guidance on the design of formwork and the flow characteristics of the grout can be obtained from Sika technical department but for estimating purposes a 200 mm head of Ronagrout GP will flow approximately 2 m through a gap of 20 mm.

CLEANING OF TOOLS

Clean all tools and application equipment with clean water immediately after use.
