MasterRheobuild 1100 A high range water reducing superplasticiser for rheoplastic concretes
Formerly: Rheobuild 1100
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
