Admixture standards in individual European countries were phased out during 2002 and a new European Standard EN 934 introduced, covering all the main types of admixture. This standard is currently divided into five parts. EN 934, covers admixtures for concrete (Part 2), mortar (Part 3), grout (Part 4) and sprayed concrete (Part 5).

To that end, MasterGlenium 7920 admixture was used to help disperse cement particles and provide an environment for easy mixing of the materials. Furthermore, BASF's MasterLife 300D admixture facilitates the growth of crystals to fill voids in cracks within concrete to help keep it watertight.
Developed by EdenCrete Industries Inc., EdenCrete® is a carbon nanotube enriched liquid additive that elevates concrete structures to new levels of strength and toughness. When added to concrete mixtures, it performs like multiple additives rolled into one.
All these additives have been used for many years and have a good track recoerd, but now we will have to learn to use them in conjunction with admixtures that are key components of modern concrete. In particular when using a superplasticizer it is possible to get cementitious particles very close to each other to make a stronger and more ...

Fresh concrete frozen during the first 24 hours can lose 50% of its potential 28 day strength. A number of these problems can be overcome through the addition of admixtures to concrete. Accelerators. Accelerating admixtures can help offset the effects of low temperatures by …
While all other admixtures have been tested and found to have no long-term detrimental effects on colored concrete, they may shift the color lighter or darker. This makes it that much more important to maintain batch-to-batch consistency. Never switch admixtures or stop using them in the middle of a colored concrete project!
An admixture which, when added to concrete, mortar, or grout, increases the rate of hydration of hydraulic cement, shortens the time of set in concrete, or increases the rate of hardening or strength development. Accelerating admixtures can be divided into groups based on their performance and application: Set Accelerating Admixtures,
