About Fosroc Renderoc RG Micro Concrete Non Shrink, Packaging Size: 25 Kg
Renderoc RG is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free-fl owing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fi llers, and additives which impart controlled expansion characteristics in the plastic state, while minimising water demand. The low water requirement ensures high early strength and long-term durability.Main Uses
For larger repairs, the mixed Renderoc RG may be modified by the addition of 5mm to 12mm clean, graded, saturated surface dry aggregates at site. For exceptionally large repairs, the local Fosroc office shall be consulted.
Advantages
- Gaseous expansion system compensates for shrinkage and settlement in the plastic state.
- Can be pumped or poured into restricted locations.
- Highly fluid to allow for placement without vibration.
- Pre-packed to overcome site-batched variations.
- Rapid strength gain to facilitate early reinstatement.
- High ultimate strengths and low permeability of cured repair.
- Contains no chloride admixture.
Superior Strength and DurabilityRenderoc RG Micro Concrete achieves high compressive strength rapidly-20-25 MPa in 1 day and up to 60 MPa in 28 days-ensuring strong and reliable repairs for critical structural elements. Its non-shrink formulation prevents cracking and guarantees volume stability, making it particularly suitable for the rehabilitation of damaged concrete areas.
User-Friendly ApplicationSupplied as a ready-to-use grey powder, Renderoc RG only requires water addition during mixing. Its flowable consistency enables easy placement even in restricted spaces, ensuring thorough compaction and integration with existing concrete. With a working time of approximately 30 minutes at 30C, users have ample time to complete repairs efficiently.
FAQ's of Fosroc Renderoc RG Micro Concrete Non Shrink, Packaging Size: 25 Kg:
Q: How should Fosroc Renderoc RG Micro Concrete be applied for optimal results?
A: To achieve the best results, thoroughly mix the powder with clean water as per manufacturer instructions until a uniform, flowable consistency is attained. Pour or pump the mixed micro concrete into prepared, formwork-confined areas for concrete repair, jacketing, or void filling. Ensure the substrate is clean, damp, but free of standing water prior to application.
Q: What are the primary uses of Renderoc RG Micro Concrete?
A: Renderoc RG is commonly used for the repair and reinstatement of structural integrity in reinforced concrete (RC) members such as columns, beams, and floors. It is suitable for jacketing, grouting, encasement repairs, and filling voids in damaged or deteriorated concrete structures.
Q: When is Renderoc RG the preferred choice for concrete repair?
A: Renderoc RG is ideal when high early strength, non-shrink properties, and flowability are required-especially for repairs in structural RC elements that need fast return to service or where access is limited and good compaction of conventional concrete is difficult.
Q: Where should Renderoc RG be stored before use?
A: Store Renderoc RG in its original, unopened packaging in a cool, dry place away from moisture. Proper storage extends the shelf life to six months and preserves the material's quality and effectiveness.
Q: What benefits does Renderoc RG offer over traditional repair mortars?
A: Renderoc RG offers a chloride-free, non-shrink, and flowable formulation that delivers rapid strength gain, minimizes shrinkage cracks, and integrates seamlessly with existing structures. Its high durability and compatibility make it especially suitable for industrial and structural repairs.
Q: Is Renderoc RG Micro Concrete safe and environmentally friendly?
A: Yes, Renderoc RG is non-poisonous, odourless, and free from added chlorides, making it safe for use in reinforced concrete repairs without risking corrosion. Always follow safety guidelines provided in the product documentation.
