(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.

They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength development. The particular configuration of the MasterGlenium SKY molecules allows their delayed absorption onto the cement particles and disperses them effectively over a long period of time.
This page is available in the following languages: 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.
Water Reducers, High-Range
The strength of concrete increases when the water to cement ratio decreases. Cement and Concrete Composites.
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. The polyethylene oxide PEO or MPEG group affords a not uniform distribution cpncrete electron cloudhlenium gives a chemical polarity to the side chains.
Retrieved from ” https: MasterGlenium Enhanced slump retention High early strengths Operational efficiency. MasterRheobuild Extended slump retention Cohesive and non-segregating Minimal bleed water. This effect drastically improves the performance of the hardening fresh paste.
The new generation of this kind of admixtures is represented by polycarboxylate ether-based superplasticizers PCEs. Cement Concrete Chemistry Colloidal chemistry Heterogeneous chemical mixtures.
Master Glenium Water Reducer | Concrete Exchange
These polymers are used as dispersants to avoid particle segregation gravel, coarse and fine sandsand to improve the flow characteristics rheology of suspensions such as in concrete applications. Journal of Colloid and Interface Science. 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.
With a relatively low dosage 0.
MasterGlenium 7500: Full-range water-reducing admixture
MasterGlenium Superior early-age strengths Excellent precast-prestress product Faster turnover of forms. Visit our download center.
This page was last edited on 19 Decemberat PCEs are composed by a methoxy- polyethylene glycol copolymer side chain grafted with methacrylic acid copolymer main chain. MasterGlenium Rapid cement dispersion Shorter mixing time, especially in high performance mixtures Increased productivity. Close Select your language.

However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. Superplasticizersalso known as high range water reducersare chemical admixtures used where well-dispersed particle suspension is required.
Excellent concrete performance in fresh and hardened states. From Wikipedia, the free encyclopedia. Close Please select your location.
This new generation of superplasticizers guarantees a concrete that meets the original specification from the fresh to the hardened stage.
