Use of Water Reducers, Retarders, and Supizers.

2000-3-30  Supizers are soluble macromolecules, which are hundreds of times larger than water molecule (Gani, 1997). Mechanism of the supizers is known as adsorption by C 3 A, which breaks the agglomeration by repulsion of same charges and releases entrapped water. The adsorption mechanism of supizers is partially different from

A simplified view on chemical effects perturbing the

1. Introduction. Dispersion of agglomerated cement particles is recognized to constitute the main way by which supizers improve the ability of concrete without increasing the water content , , , , .Quantifying this mechanism is a difficult task and is further complicated by the ongoing hydration reactions of cement .To overcome this difficulty various authors have chosen to study

Plasticizer - Wikipedia

  

2019-10-16  Adding 1-2% plasticizer per unit weight of cement is usually sufficient. Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical used, use of too much plasticizer may result in a retarding effect.

Cement - Supizer Compatibility

2011-9-19  While the mechanism of action of water-reducing chemicals is reasonably well-established, there still exist gaps in the comprehension of why occasionally these chemicals do not as intended. This is because the problem of cement-supizer compatibility has many dimensions to it.
