(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 new generation of superplasticizers guarantees a concrete that meets the original specification from the fresh to the hardened stage. 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.

The number and the length of side chains are flexible parameters that are easy to change. 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. Retrieved from ” https: MasterGlenium Enhanced slump retention High early strengths Operational efficiency. Cookies help us deliver our services.

Their addition to concrete or mortar allows the reduction of the water to cement ratio without negatively affecting the workability of gleniim mixture, and enables the production of self-consolidating concrete and high performance concrete. This effect drastically improves the performance of the hardening fresh paste. 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.

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. MasterGlenium Superior early-age strengths Excellent precast-prestress product Faster turnover of forms. From Wikipedia, the free encyclopedia.
