MasterRheobuild 857AD - A high range, water reducing superplasticiser for concretes containing GGBS and microsilica
How does MasterRheobuild 857AD work?
MasterRheobuild 857AD is formulated from
synthetic polymers specially designed to impart
rheoplastic qualities to concrete, particularly those
containing GGBS or microsilica.
A rheoplastic concrete is a fluid concrete with a
slump of at least 200 mm, easily flowing, but at the
same time free from segregation and having the
same water/cement ratio as that of a low slump
concrete (25 mm) without admixture.
MasterRheobuild 857AD is chloride free
What is MasterRheobuild 857AD used for?
- Mixes containing GGBS or microsilica
- Mass concrete pours
- Ready mixed concrete
- Pumped concrete
- Casting in hot climates
- High workability for longer periods
- Lower pumping pressure
- Delayed setting with longer workability
- Higher ultimate strengths.
- Reduced permeability
- Improved durability
What are the advantages of MasterRheobuild 857AD?
MasterRheobuild 857AD considerably improves
the properties of fresh and hardened concrete.
