(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.

This page was last edited on 19 Decemberat 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 new generation of this kind of admixtures is represented by polycarboxylate ether-based superplasticizers PCEs. The addition of superplasticizer in the truck during transit is a fairly new development within the industry.
PCE’s backbone, which is negatively charged, permits the adsorption on the positively charged colloidal particles. 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.

Water Reducers, High-Range
MasterRheobuild Extended slump retention Cohesive and non-segregating Minimal bleed water. MasterGlenium Superior early-age strengths Excellent precast-prestress product Faster turnover of forms. This new generation of superplasticizers guarantees a concrete that meets the original specification from the fresh to the hardened stage. Cement and Concrete Composites. They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength gleium.
When the condrete 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. However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. Close Login Please login with your username and password.
