Sikament® RB 561 (formerly known as MasterRheobuild® 561) - A superplasticising admixture to produce low slump loss rheoplastic concrete

How does MasterRheobuild 561 work?

MasterRheobuild 561 is a chloride free, ready-to-use, liquid admixture comprising of synthetic polymers specially designed to impart low slump rheoplastic qualities to concrete. Rheoplastic concrete is a fluid concrete with a slump value of at least 200mm, easily flowing but at the same time free from segregation and having the same water/cement ratio as that of a no-slump concrete without additive.

What makes MasterRheobuild 561 a unique solution?

MasterRheobuild 561 has been formulated to meet the requirements of ASTM C494 Type B, D and G, BS5075 Part 3 and UNI no. 7102, 7104 -72 and 8145 for high range water-reducing admixtures. It is compatible with all cements meeting recognised international standards.

What are the features and benefits of MasterRheobuild 561?

• Very high workability - Short placement time. Saves time and labour.
• High water reduction - High impermeability and strength. Improves durability.
• Superior cohesion - No segregation even at high workability. Excellent concrete quality.
• Low shrinkage and creep - Better dimensional stability.
