What is Fosroc Renderoc RG?
A Brief Introduction to Microconcrete : Renderoc RG is a general-purpose , non-shrink , cementitious microconcrete . This advanced material is designed for repairs where access is limited and vibration is impractical . As a ready-to-use blend, it only requires the addition of water at the site, making it convenient for various structural repairs .
Composition and Design of Renderoc RG : The product consists of Portland cements, graded aggregates, and special additives . These ingredients give Renderoc RG its unique shrinkage-compensating properties in the plastic state, allowing it to gain strength quickly and cure with minimal water content. This results in a durable, long-lasting repair solution .
Key Uses of Fosroc Renderoc RG
Renderoc RG is ideal for numerous concrete repair applications , particularly where structural integrity is at stake .
Structural Strengthening : One of the primary uses of Renderoc RG is structural strengthening . It can be used for large repair sections, including areas that are hard to reach, such as beams and columns .
Concrete Encapsulation and Jacketing : It’s also effective for encasement and jacketing of weakened concrete structures, ensuring they regain their former strength without the need for complex machinery or labor - intensive processes .
Pile Top Encasement : For projects requiring pile top encapsulation, Renderoc RG proves invaluable , offering robust reinforcement that withstands both environmental and structural stresses .
The Advantages of Using Fosroc Renderoc RG
Gaseous Expansion for Shrinkage Compensation : One of the standout features of Renderoc RG is its gaseous expansion system, which compensates for shrinkage and settlement in the plastic state . This ensures the microconcrete remains dimensionally stable , even under significant loads .
High Fluidity for Easy Application : Renderoc RG boasts excellent fluidity , allowing it to be poured or pumped into confined spaces with ease . No vibration is required during application , making it perfect for hard-to-reach areas .
Rapid Strength Gain for Quick Repairs : Another advantage is its rapid strength gain . Within 24 hours, Renderoc RG achieves a compressive strength of 10 N/mm², reaching up to 50 N/mm² within 28 days . This fast curing time facilitates quick repairs and minimizes downtime .
Pre-packed for Consistent Quality : Since it comes pre-packed , Renderoc RG eliminates the risk of inconsistencies that often arise from site-batched mixes. This ensures that each repair is executed to the highest standard .
Chloride-free Composition for Corrosion Resistance : Renderoc RG contains no chlorides , making it a safe choice for concrete repairs in environments where corrosion is a concern, such as coastal regions or areas with high humidity .
Design Criteria for Fosroc Renderoc RG Applications
Application Depths and Aggregates : Renderoc RG can be applied in sections of up to 100mm in depth . For deeper applications , the addition of 5mm to 12mm clean, graded aggregates may be necessary. In such cases, it’s always best to consult your local Fosroc office for guidance .
Temperature and Curing Conditions : The product should be applied under the right conditions, especially in high-temperature environments, where additional curing techniques like wet hessian may be required to ensure the material performs as expected .
Step-by-step Application of Fosroc Renderoc RG
Surface Preparation and Reinforcement Cleaning : Before applying Renderoc RG , it's crucial to prepare the surface by cleaning away defective concrete and ensuring the reinforcement is exposed and free from corrosion . This guarantees a strong bond between the new and existing concrete .
Mixing Instructions for Optimal Results : Mixing is best done with a forced-action mixer to achieve an even , smooth consistency . A water-to-powder ratio of 0.16 is ideal . In larger repairs, adding pre - approved graded aggregates may be necessary .
Formwork Installation : Slurry - tight formwork is essential for holding the microconcrete in place . Make sure the formwork can withstand the hydraulic pressure and provide air vents to prevent air entrapment .
Placing the Microconcrete : Once mixed, Renderoc RG should be placed immediately, either by pouring or pumping. Standard concrete pumping practices should be followed to ensure proper distribution and prevent air pockets .
