(Formerly known as GLENIUM 51) and Table 7: High range water reducing/Super plasticizer. Concrete n Improves concrete’s mechanic properties. Glenium is particularly effective in improving the day to day consistency of concrete mixtures. This is accomplished by providing unparalleled slump. Use Master Glenium Water Reducer with your concrete, a full-range water- reducing admixture that is highly effective in producing concrete mixtures with.

The polyethylene oxide PEO or MPEG group affords a not uniform conxrete of electron cloudcncrete gives a chemical polarity to the side chains. MasterRheobuild Extended slump retention Cohesive and non-segregating Minimal bleed water. Excellent concrete performance in fresh and hardened states. Their addition to concrete or mortar allows the reduction of the water to cement ratio without negatively affecting the workability of the mixture, and enables the production of self-consolidating concrete and high performance concrete.

MasterGlenium SKY New generation polycarboxylic ether hyperplasticiser for high performance concrete. MasterGlenium Rapid cement dispersion Shorter mixing time, especially in high performance mixtures Improved concrete production productivity.
With a relatively low dosage 0. Superplasticizersalso known as high range water reducersare chemical admixtures used where well-dispersed particle suspension is required.
The new generation of this kind of admixtures is represented by polycarboxylate ether-based superplasticizers PCEs. Journal of Colloid and Interface Science.
Water Reducers, High-Range
Cement and Concrete Research. PCE’s backbone, which is negatively charged, permits the adsorption on the positively charged colloidal particles.
The addition of superplasticizer in the truck during transit is a fairly new development within the industry.
This new generation of superplasticizers guarantees a concrete that meets the original specification from the glenijm to the hardened stage. Cement and Concrete Composites.

These polymers are used as dispersants to avoid particle segregation gravel, coarse and fine sandsand to improve the flow characteristics rheology of suspensions cobcrete as in concrete applications.

Master Glenium Water Reducer | Concrete Exchange
Admixtures added in transit through automated slump management systems, such as Verifi, comcrete allows concrete producers to maintain slump until discharge without reducing concrete quality. Cookies help us deliver our services. When the side chains have a huge amount of EO units, they lower with their high molar mass the charge density of the polymer, which enables poor performances on cement suspensions.
From Wikipedia, the free encyclopedia.
The number and the length of side chains are flexible parameters that are easy to change. Cookies help us deliver our cohcrete. They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength development. However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities.
Retrieved from ” https: MasterGlenium Enhanced slump retention High early strengths Operational efficiency.
As a consequence of PCE adsorption, the zeta potential of the suspended particles changes, due to the adsorpsion of the COO- groups on the colloid surface. This displacement of the polymer on the particle surface ensures to the side chains the possibility to exert repulsion forces, which disperse the particles of the suspension and avoid friction.

The technology and versatility of the superplasticizers portfolio excels in high performance areas such as high strength concrete, pumpability, self-consolidating concrete, low permeability, low water absorption concrete and low shrinkage applications.
