MasterRheobuild 1000

High-range water-reducing admixture

How does MasterRheobuild 1000 work?

MasterRheobuild 1000 high-range, water-reducing admixture is formulated to produce rheoplastic concrete. Rheoplastic concrete flows easily, maintaining high plasticity for time periods longer than conventional super-plasticized concrete. Rheoplastic concrete has the low water-cementitious materials ratio of no-slump concrete, providing excellent engineering (hardened) properties. The slump-retention characteristics of rheoplastic concrete permit the addition of MasterRheobuild 1000 admixture at the batch plant. MasterRheobuild 1000 admixture meets ASTM C 494/C 494M requirements for Type A, water-reducing, and Type F, high-range water-reducing, admixtures.

Recommended uses:

Concrete where high plasticity, normal-setting characteristics and accelerated strengths are desired
Prestressed, precast and ready-mixed concrete applications
Civil and mining applications

What are the unique features of MasterRheobuild 1000?

In the plastic state:

Range of 8-11 in. (200-280 mm)
Extended slump retention
Controlled set times
Cohesive and non-segregating
Minimal bleed water

In the hardened state:

Higher earlier strengths than can be achieved with conventional high-range water reducers
Increased ultimate compressive strength
Higher modulus of elasticity
Improved bond strength to steel
Low permeability
High durability
Reduced shrinkage and creep
Highly reliable in-place structural integrity

What are the benefits of MasterRheobuild 1000?

Less dependence on consolidation energy
Job time and cost reduced through higher productivity rates and/or reduced labor
Early strength allows for accelerated construction methods, resulting in completion dates ahead of schedule
Engineering specification changes can allow for greater limits on the free-fall of concrete, lift heights, concrete temperatures and potential economic mixture adjustments
