(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.

Excellent concrete performance in fresh and hardened states. Cement Concrete Chemistry Colloidal chemistry Heterogeneous chemical mixtures. This page is available in the following languages: Cookies help us deliver our services. The strength of concrete increases when the water to cement ratio decreases.
MasterGlenium Superior early-age strengths Excellent precast-prestress product Faster turnover of forms. Retrieved from ” https: Journal of Colloid and Interface Science. PCE’s backbone, which is negatively charged, permits the adsorption on the positively charged colloidal particles. Cookies help us deliver our services. Admixtures added in transit through automated slump management systems, such as Verifi,  allows concrete producers to maintain slump until discharge without reducing concrete quality.

Downloads Admixture Systems Brochure. However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. MasterGlenium SKY New generation polycarboxylic ether hyperplasticiser for high performance concrete. The new generation of this kind of admixtures is represented by polycarboxylate ether-based superplasticizers PCEs. Superplasticizersalso known as high range water reducersare chemical admixtures used where well-dispersed particle suspension is required.
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. The number and the length of side chains are flexible parameters that are easy to change. Keep me signed in. Close Select your language.
These forces can be directly detected by the use of the atomic force microscopy AFMworking with model substances in liquid environment. Cement and Concrete Research.
MasterGlenium SKY – Superplasticizer for ready-mix concrete

MasterGlenium Rapid cement dispersion Shorter mixing time, especially in high performance mixtures Improved concrete production productivity. This displacement of the polymer on voncrete particle surface ensures to the side chains the possibility to exert repulsion forces, which disperse the particles of the suspension and avoid friction. Can’t access your comcrete Compared to conventional PCE superplasticizers, glnium MasterGlenium SKY range enables ready-mix producers to optimize inventory, facilitate logistics and reduce investments in tanks and dispenser equipmentthus also decreasing maintenance costs.

MasterGlenium Enhanced slump retention High early strengths Operational efficiency. Cement and Concrete Composites. 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.
The addition of superplasticizer in the truck during transit is a fairly new development within the industry. The polyethylene oxide PEO or MPEG group affords a not uniform distribution of electron cloudwhich gives a chemical polarity to the side chains. 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.
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. They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength development.
