Thickness swelling (EN 317) was measured with samples(11 × 50 × 50 mm3) fully immersed in 20◦C distilled water. Thickness swelling and water absorption was measured after 2 h and24 h, respectively. As soon immersion time has elapsed the samples were taken out from the water bath with excess water removed with paper tissues. Thickness swelling was measured in the mid of the sample by a caliper. The water absorption was determined by weighing using a scale Radwag mac 210 (Radwag USA L.L.C.,Florida, United States of America) with the precision of 1 mg. The sample weight was recorded and consequently used for calculation of water soaking in percent.
