MasterRheobuild 1100 A high range water reducing superplasticiser for rheoplastic concretes

How does MasterRheobuild 1100 work?

MasterRheobuild 1100 is a high range water reducing superplasticiser. It is based on negatively charged molecules of synthetic polymers which when dispersed within the fresh concrete absorb onto the surface of the cement grains. After the molecules are absorbed they create an electrostatic repulsion amongst the cement grains, making their dispersion in water easier and consequently the concrete mix is more flowable.

MasterRheobuild 1100 is formulated to produce rheoplastic concrete. Rheoplastic concrete flows easily, maintaining high plasticity for time periods longer than conventional superplasticised concrete. Rheoplastic concrete has a similar water-cement ratio to zero slump concrete, and enhances the hardened properties of the concrete.

MasterRheobuild 1100 meets the requirements of:

• ASTM C-494 Type A and F
• EN 934-2 Tables 3.1 and 3.2

What is MasterRheobuild 1100 used for?

MasterRheobuild 1100 is designed for use in the manufacture of high quality structural concrete; pre-cast concrete; pre-stressed and post tensioned concrete; high early strength, high workability concrete.

MasterRheobuild 1100 is used to increase and extend workability, increase compressive strength and effect cement economies. The wide dosage range of MasterRheobuild 1100 enables water reductions to produce a dense concrete with reduced permeability and reduced water penetration.

MasterRheobuild 1100 is also used in areas of congested reinforcement where high workability is of benefit; wherever reduced water contents would be of benefit and in hot weather to extend workability.

What are the benefits of MasterRheobuild 1100?

MasterRheobuild 1100 has been formulated specifically for use in the Middle East climate and it offers the following advantages:

• Less dependence on compaction energy
• Job time and cost reduced through higher productivity rates and/or reduced labour
• Early strength allows for accelerated construction methods, resulting in completion dates ahead of schedule ​

MasterRheobuild 880 – A high range, water-reducing superplasticiser for rheoplastic concretes​

Description

MasterRheobuild 880 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete. A rheoplastic concrete is a fluid concrete, easily flowing, but at the same time free from segregation and bleeding having the same w/c ratio as that of a low slump concrete without admixture. MasterRheobuild 880 is chloride-free.

Where is MasterRheobuild 880 applied?

• Microsilica concrete 
• Mass concrete pours
• Ready-mixed concrete 
• Long-distance transport 
• Pumped concrete
• Casting in hot climates 

What are the advantages of MasterRheobuild 880?

• Reduced thermal peaks
• High workability for longer periods 
• Lower pumping pressure 
• Delayed setting with longer workability 
• Higher ultimate strengths 
• Reduced permeability 
• Improved durability 

MasterRheobuild 875 – A high range, water-reducing, superplasticising admixture for the production of rheoplastic concrete

Description

The basic components of MasterRheobuild 875 are synthetic polymers, which allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. 

MasterRheobuild 875 is a chloride-free product.

Where is MasterRheobuild 875 applied?

• Production of rheoplastic self-compacting concrete 
• Pre-cast concrete 
• Low w/c ratio concrete 
• In complicated formwork or with congested reinforcement 

What are the advantages of MasterRheobuild 875?

• MasterRheobuild 875 allows the production of very flowable concrete, with a low w/c ratio. 
• Concrete with MasterRheobuild 875 shows strengths higher than concrete without admixture having the same workability. 
• The increase in strength, especially evident at early ages, remains at later ages, both in air cured and steam cured processes. 
• Initial and final sets do not change significantly with respect to concrete without admixture.
