​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​
