-Its exchange with the surroundings causes hardened concrete to shrink, swell, and possibly crack;
-Its presence in hardened concrete influences the strength and creep;
-It plays a central role in deterioration caused by frost action or alkali;
Obviously, control of water is important to concrete. We will give an overview of some of the opportunities offered by the use of SOCO Polymer for achieving that control.
SOCO Polymer (super absorbent polymer for concrete) is polymeric materials that have the ability to absorb a large amount of liquid from the surroundings and retain it within their structure.
It belongs to the group of so-called “smart materials”— materials that, in a controlled way, significantly change their properties in response to an external stimulus. When It is exposed to water, they swell, and when subsequently subjected to drying, it reversibly shrink. These key properties can actively be used in relation to concrete.
As mentioned in the introduction, it has extreme water absorption characteristics; this makes them particularly interesting in relation to concrete. Due to the water absorption, SOCO polymer may also be considered a means to control porosity, which is another important property for concrete. Because it can be designed with other specific properties, however, many additional uses of SOCO Polymer in concrete may be relevant. Examples include:
-It with fibrous shapes potentially can be used to make high
-Can be used as an internal sealant in cement-based materials.
-A special use of SOCO Polymer in concrete could be as a controlled release agent.
