GLENIUM CONCRETE PDF

(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.

MasterGlenium Enhanced slump retention High early strengths Operational efficiency. PCE’s backbone, which is negatively charged, permits the adsorption on the positively charged colloidal particles. Close Please select your location.

Water Reducers, High-Range

Close Please select your language This page is available in the following languages: MasterGlenium SKY products offer a single, versatile admixture for many types of concrrte and conditions. Master Builders Solutions Technical Support. This page was last edited on 19 Decemberat These forces can be directly detected by the use of the atomic force microscopy AFMworking with model substances in liquid environment.

Admixtures added in transit through automated slump management systems, such as Verifi, [2] allows concrete producers to maintain slump until discharge without reducing concrete quality. As a consequence of PCE adsorption, the zeta potential of the suspended concfete changes, due to the adsorpsion of the COO- groups on the colloid surface.

MasterGlenium Rapid cement dispersion Shorter mixing time, especially in high performance mixtures Improved concrete production productivity. Can’t access your account? By using this site, you agree to the Terms of Use and Privacy Policy. Cookies help us deliver our services.

The polyethylene oxide PEO or MPEG group affords a not uniform distribution of electron cloudwhich gives a chemical polarity to the side chains. This new generation of superplasticizers guarantees a concrete that meets the original specification from the fresh to the hardened stage. MasterGlenium SKY New generation polycarboxylic ether hyperplasticiser for high performance concrete.

Views Read Edit View history. They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength development. Cookies help us deliver our services. This effect drastically improves the performance of the hardening fresh paste. MasterGlenium Superior early-age strengths Excellent precast-prestress product Faster turnover of forms. Close Please select your location. The new generation of this kind of admixtures is represented by polycarboxylate ether-based superplasticizers PCEs.

Keep me signed in. 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. 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.

With a relatively low dosage 0. However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. 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.

MasterGlenium 7500: Full-range water-reducing admixture

This page is available in the following languages: Visit our download center. Gleniim to conventional PCE superplasticizers, our MasterGlenium SKY range enables ready-mix producers to optimize inventory, facilitate logistics and reduce investments in tanks and dispenser equipmentthus also decreasing maintenance costs.

Superplasticizersalso known as high range water reducersare chemical admixtures used where well-dispersed particle suspension is required.

The number and the length of side chains are flexible parameters that are easy to change. Cement and Concrete Research.

MasterGlenium SKY – Superplasticizer for ready-mix concrete

Journal of Colloid and Interface Science. Cement Concrete Chemistry Colloidal chemistry Heterogeneous chemical mixtures.

PCEs are composed by a methoxy- polyethylene glycol copolymer side chain grafted with methacrylic acid copolymer main chain. By using our services, you agree to our use of cookies. The strength of concrete increases when the water to cement ratio decreases. 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.
