Shrinkage Compensated High Flow General Purpose Cement Grout

Ronagrout GP

DescriptionRonagrout 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 40MPa. It can be applied in thick or thin section and is suitable for structural and non- structural repairs such as honeycomb-ing. Ronagrout GP contains an expan-sive 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.

Benefits Controlled expansion to compensate for shrinkage and settlement in plastic state Can be used as a patching mortar or flowable grout Application 10mm up to 100mm thick per layer (Maximum 25mm 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

PackagingRonagrout GP is supplied in 25kg bag. The approximate yield is 13.5 litres depending on the amount of water added and the mixing method used.

Surface PreparationGenerally the concrete substrate must be clean, sound and free from all deleterious material. Laitance, dirt and contamination must be removed by water jetting, scabbling, grit blasting or similar following which all dust and debris must be removed. Bolt holes and fixing pockets must be free of any dirt or debris, base plates must be free of oil, grease and loose rust.For concrete repair application, all defective concrete should be removed to leave a sound stable substrate for the repair material. Loose rust and scale should be removed from exposed reinforcement and reinforcement should be primed. Cut around the perimeter of the repair areas to a minimum depth of 20mm to avoid feather edges and prime if necessary.Surface Priming Concrete surfaces to be primed must first be thoroughly wetted with clean water. Mix the primer by the following ratio: Ronafix : Cement = 1:1.5 by volume OR 1:2.0 by weight Prime the steel reinforcement and allow to become tacky Prime the steel reinforcement again and the previously dampened concrete surfaces.FormworkFormwork must be grout tight and rigid enough to prevent deformation during the grouting process. Formwork should be so designed as to enable a hydrostatic head to be maintained at all times during the grouting operation. Unrestrained areas around the element to be grouted should be kept to a minimum.MixingA 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 25kg 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. Ronacrete 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 5.0L per 25kg bag. For pourable application the water should be in the range 4.0 to 5.0L per 25kg bag. For free flow grouting applications the water addition should be 5.0L per 25kg 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.InstallationRonagrout GP can be placed in thicknesses ranging from 10mm to 100mm in one single application. For application thicknesses over 100mm Ronagrout GP can be extended with the addition of a clean, sound and well graded 5mm to 10mm aggregate. A maximum of 25kg of aggregate per 25kg of Ronagrout GP is recommended.For vertical and overhead patch repair works Ronacrete recommend keeping the water addition to a minimum and limiting layer thicknesses to 25mm.Detailed information and guidance on the design of formwork and the flow characteristics of the grout can be obtained from Ronacrete technical department but for estimating purposes a 200mm head of Ronagrout GP will flow approximately 2m through a gap of 20mm.Storage and Shelf LifeShelf Life is 9 months. Store in the original and unopened bags in dry conditions. Exposure to high humidity and/or high temperature may reduce the shelf life.Health and SafetyRonagrout GP is non-hazardous although protective clothing such as goggles, overalls and gloves is recommended to prevent prolonged skin contact, inhalation or ingestion.In the event of skin contact, wash with soap and water. Seek medical advice if irritation or pain occurs. In the event of eye contact, irrigate with plenty of clean water and seek immediate medical advice. In the event of ingestion, wash mouth with plenty of clean water. Do not induce vomiting. Seek medical advice.Technical Service and SupportRonacrete provide free technical advice and support during design and installation of all systems for flooring, concrete repair, bonding, bedding and waterproofing.
