Plasticizer
The plasticizing are Enduit S recovering the plasticized fabrics, with an aim of making them more resistant, of protecting them from the external wear and elements. For example, the triethylene glycol is plasticizing for the Vinyle.
The concrete Additive
In the field of the chemistry of the Concrete, it is about an additive, built-in during the manufacture of that Ci, and which and which increases the rheology of the freshly-mixed concrete (before hardening). The mechanical characteristics of the concrete thus adjuvanté, are seen some also improved. One speaks in this case about reducing plasticizer about water. The latter intervene by reduction of report/ratio E/C (water/cement).The reduction of the capillarity (of the vacuums interns) material concrete, implies an increase in the mechanical resistance of this one (resistance expressed in a Méga-Pascal (MPa). If initial water proportioning is not modified, one will then obtain an increase in the rheology of the freshly-mixed concrete. Rheology will be it, measured using a slump test (in this case it is the depression of the freshly-mixed concrete which will be measured).
The most current big families of plasticizers are:
- Lignosulphonates
- naphthalenes
- the Melamines
- vinyl copolymers
