Water Absorption The water absorption was tested on the plates made of Grovebetong supplied by Webers AB, Goteborg. The samples were cure according to the Swedish standard. The 28 days cube compressive strength is 40 MPa .The plates were coated with Florosil (Fl), Creom (Cr), and Condry (CON) two times at the interval of 12 hours (1 day). These plates were put over wet sand bed in a box, the water was poured so much so that the bottom of the samples were only in contact with the wet sand. The aim is that the water penetration will only be through the capillary suction. The plates were weighed at particular intervals. The weights reported are when it has reached saturation point. It means there was no further absorption. Water absorption is calculated in weight percent. The samples were dried to constant weight after the test and the weight change was calculated.

Water Vapor Transport Test The samples after drying were sealed over a steel pot filled with eater, with the coated surface downwards. The area of the pot was of 14 cm diameter. The area exposed is Π r 2 ; 3.14X7x7= 154 square cm. It was heated, the steam transported through the coated surface. The t4est was done for 4 hours. The samples were weighed, the weight change is determined and the vapor transmission is calculated. The results are reported in vapor transmission per square meter per hour. kg/hr/m 2 = 10x g/hr/cm 2 KARL GUSTAVSGATAN 22B, Tel.+46 31-454920 S-411 25 GOTHENBURG, SWEDEN Org. nr: 5562375435 © IdéTrading AB.

Results The results show that the water absorption of the plates coated with Florosil is 1.4 times less than the normal concrete with respect to the weight at room temperature and 1.8 times less than the normal concrete with respect to the dry weight The results show that the water absorption of the plates coated with Creom CR is 1.8 times less than the normal concrete with respect to the weight at room temperature and 2.03 times less than the normal concrete with respect to the dry weight The results show that the water absorption of the plates coated with Condry “CON “ is 4.37 times less than the normal concrete with respect to the weight at room temperature and 4.26 times less than the normal concrete with respect to the dry weight The results sow that the water absorption of the plates coated with CONDRY “CON” is 3.2 times less than the concrete coated with Florosil with respect to the weight at room temperature and 2.4 times less with respect to the dry weight The results sow that the water absorption of the plates coated with CONDRY “CON” is 2.43 times less than the concrete coated with Creom with respect to the weight at room temperature and 2.10 times less with respect to the dry weight The results show that the vapor transmission of the plates coated with Florosil is 1.6 times less than the normal concrete The results show that the vapor transmission of the plates coated with Creom CR is 2.04 time less than the normal concrete The results sow that the vapor transmission of the plates coated with CONDRY CON is 5.5 times less than the normal concrete The results show that the vapor transmission of the plates coated with CONDRY CON is 3.8 times less than the concrete coated with Florosil. The results show that the vapor transmission of the plates coated with CONDRY CON is 2.3 times less than the concrete coated with Creom. Furthermore, the surface of Florosil treated concrete is too soft, it can be scratched away whereas the surface treated with Condry is hard. Dr.Satish Chandra Rtd.
