The Influence of Air<br />
The preparation of mortar and concrete always<br />
requires mixing. These shear forces naturally lead to<br />
dispersion of air.<br />
The presence of air in cementitious systems<br />
is inevitable<br />
• Small air voids are desirable (easy flow, isolation,<br />
uptake of stress)<br />
• Too much air or large air voids are unwanted<br />
(loss of strength, surface defects)<br />
Use defoamers to control amount of air<br />
Air voids homogenously distributed<br />
Air voids inhomogenously distributed<br />

Evolution of Evonik’s Defoamers<br />
First generation of antifoams from Evonik:<br />
• TEGO® AF P 205 for mortar and all other<br />
cementitious systems<br />
• TEGO® AF P 210 designed especially for selfleveling<br />
underlayments (SLUs)<br />
Second generation of antifoams was developed to:<br />
• increase performance<br />
• improve cost efficiency<br />
• achieve additional benefits<br />
