MasterRheobuild® 820 | MCT CHEMICALS | MASTER BUILDER SOLUTION

Usage of MasterRheobuild® 820:

1. High-Performance Concrete: MasterRheobuild® 820 is used in high-performance concrete applications, enhancing the mix’s flowability and reducing the water-to-cement ratio, thereby improving the strength and durability of the final product.
2. Self-Consolidating Concrete (SCC): This product is commonly used in the production of SCC, where it helps the mix achieve the desired level of fluidity and flow without the need for vibration, ensuring uniform distribution and excellent surface finish.
3. Ready-Mix Concrete: MasterRheobuild® 820 is added to ready-mix concrete to improve its workability, reduce segregation, and allow easier placement and finishing, ensuring consistent results across large-scale projects.
4. Precast Concrete: Used in the production of precast concrete elements, MasterRheobuild® 820 helps improve the quality, strength, and workability of precast products, enabling faster form stripping and better moldability.
5. Concrete in Hot Weather: It is beneficial in hot weather conditions by helping control the rate of hydration, ensuring that the concrete maintains its workability and strength, even in extreme temperatures.

Application Coverage:

• Concrete Mixes: Typically, MasterRheobuild® 820 is used at a dosage of 0.5% to 1.5% by weight of the total cementitious content, depending on the desired flowability, strength, and durability.
• Precast and Ready-Mix Concrete: In ready-mix or precast applications, the admixture helps to achieve uniformity in the concrete mix, providing high consistency and better workability, which is essential for large-scale projects.
• Self-Consolidating Concrete (SCC): For SCC, MasterRheobuild® 820 is used to enhance flowability, enabling the concrete to fill formworks without the need for external vibration.
• Concrete in Hot Weather: In hot weather, the dosage of MasterRheobuild® 820 can be adjusted to reduce the risks of rapid hydration, ensuring the mix remains workable and retains its strength during placement and curing.

Advantages of MasterRheobuild® 820:

1. Improved Workability: MasterRheobuild® 820 significantly improves the workability of concrete, making it easier to mix, place, and finish. This is particularly beneficial in projects requiring high flowability or self-compacting concrete.
2. Enhanced Concrete Strength: By reducing the water-to-cement ratio, the admixture helps increase the compressive strength of concrete, making it ideal for applications where strength is a critical factor, such as high-rise buildings and infrastructure projects.
3. Reduced Water Usage: MasterRheobuild® 820 allows for lower water content in the mix, leading to more durable, dense, and stronger concrete with reduced permeability and enhanced resistance to cracking and weathering.
4. Self-Consolidating Concrete (SCC): It improves the flow properties of the concrete, enabling the mix to self-level and fill formworks without the need for vibration, which reduces labor costs and increases efficiency.
5. Improved Durability: The reduced water content in concrete also leads to better resistance to aggressive environmental factors, such as chemicals, freezing and thawing, and abrasion, ensuring long-lasting performance of the concrete.
6. Cost-Effective: By enhancing the workability and performance of concrete, MasterRheobuild® 820 can reduce material and labor costs while improving the overall quality and lifespan of the final product.
7. Consistent Quality: The admixture ensures that each batch of concrete meets the required strength, workability, and durability specifications, leading to more predictable and consistent results on large-scale construction projects.
8. Ideal for Hot Weather: The product helps mitigate the effects of high temperatures during mixing and curing, making it ideal for use in hot climates or during summer months, ensuring the concrete retains its properties even in challenging conditions.
