(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.

Cement and Concrete Research. They leave sufficient area on the cement surface to allow a rapid hydration reactionresulting in high early strength development. Excellent concrete performance in fresh and hardened states. Close Login Please login with your username and password. The polyethylene oxide PEO or MPEG group affords a not uniform distribution of electron cloudwhich gives a chemical polarity to the side chains.

This effect drastically improves the performance of the hardening fresh paste. 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.

Water Reducers, High-Range

However, their working mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities. 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.

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.
