MasterRheobuild3090
High range, water-reducing superplasticiser for concretes containing GGBS and microsilica
DESCRIPTION OF PRODUCT
MasterRheobuild 3090 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete, particularly those containing GGBS and microsilica. A rheoplastic concrete is a fluid concrete with a slump of at least 200mm, easily flowing, but at the same time free from segregation and having the same w/c ratio as that of a low slump concrete (25mm) without admixture.MasterRheobuild 3090 is chloride-free.
ADVANTAGES
MasterRheobuild 3090 considerably improves the properties of fresh and hardened concrete.

MasterRheobuild 2270 – A high range, water-reducing, superplasticising admixture for the production of rheoplastic concrete
Description
The basic components of MasterRheobuild 2270 are synthetic polymers, which allow mixing water to be reduced considerably and concrete strength to be enhanced significantly, particularly at early ages. MasterRheobuild 2270 is a chloride-free product.
Where is MasterRheobuild 2270 applied?
- Production of rheoplastic self-compacting concrete
- Pre-cast concrete
- Low w/c ratio concrete
- For concrete to be placed in complicated formwork or with congested reinforcement
What are the advantages of MasterRheobuild 2270?
- MasterRheobuild 2270 allows the production of very flowable concrete, with a low w/c ratio.
- Concrete with MasterRheobuild 2270 shows early 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 aircured and steam-cured processes.
- Initial and final sets do not change significantly with respect to concrete without admixture.

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 – High-range water-reducing admixtures with rheoplastic properties
How does MasterRheobuild work?
MasterRheobuild admixtures provide superior cement dispersion allowing for the production of flowable concrete with a low water/cement ratio. These specially formulated high-range water-reducing admixtures impart rheoplastic qualities to concrete that improve the placement of fresh concrete for enhanced production efficiency. This technology can be used in concrete mixes that require higher levels of fluidity and early strengths
What makes MasterRheobuild a unique solution for customers?
MasterRheobuild products have unique water-reducing properties and allow the development of fluid mixes with low permeability performance. Lower permeability minimizes water absorption and chloride ingress. The result is a more durable structure with increased service life
MasterRheobuild benefits:
Shortened placement time reducing labor requirements
Lower permeability that increases strength and improves durability
Reduces segregation even at higher levels of workability
Having the right admixture partner is vital for success.
