-It is an essential ingredient in the mixing, curing, and hardening of concrete;
-Its exchange with the surroundings causes hardened concrete to shrink, swell, and possibly crack;
-Its presence in hardened concrete influences strength and creep;
-It plays a central role in deterioration caused by frost action or alkali;
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, they 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:
