Glenium C 317 

GLENIUM C 317 is a new generation high range water reducing admixture, based on chains of modified poly carboxylic ether, primarily developed for concrete industry where high strength and durability are required.

The ability to work with very low water/cement ratio allows for the manufacture of high quality concrete.

GLENIUM C 317 is free of chloride is designed to meet ASTM C 494 requirements for Type A and Type F and it is also compatible with all cements meeting the ASTM standards.

What differentiates from the traditional high range water reducing is a new, unique mechanism of action that greatly improves the effectiveness of cement dispersion.

GLENIUM C 317 has a different chemical structure from the traditional high range water reducing. It consists of a carboxylic ether polymer with long side chains. At the beginning of the mixing process it initiates the same electrostatic dispersion  mechanism as the traditional high range water reducing, but the side chains linked to the polymer backbone generate a steric hindrance which greatly stabilises the cement particles ability to separate and disperse. With this process, flowable concrete with greatly reduced water content is obtained. The mechanism allows to obtain, compared to traditional high range water reducing admixtures, considerably higher early strengths and higher reduction of mixing water content.

In order to optimise special requirements the use of the following complementary additives is suggested:

• silica fume for high performance concrete (HPC) and improve durability in chemical aggressive environments;
• synthetic fibres to prevent cracks due to plastic shrinkage;
• curing agent MASTERKURE against too quick evaporation of mixing water GLENIUM C317 is not compatible with all admixture of RHEOBUILD series.
