Aug 15, 1995 Reference: BPSU/128 Technical Data: Subject: Water Absorption of concrete blocks Water absorption data for:: Standard concrete block Concrete block containing Tasco/Tech-Dry Block Emulsion CONTENTS 1. Description of substrates 2. Test method 3. Results 1.DESCRIPTION OF SUBSTRATES Four grey blocks of dimensions (WxDxL) 39x9x19 cm were supplied. Two of the blocks were marked "Standard 1 and Standard 2" and the other two were marked "Treated 1 and Treated 2". 2. TEST METHOD The blocks were oven dried 70C overnight, cooled and weighed. All blocks were placed in a water saturated polyurethane sponge in a water bath according to DIN52617. The mass of the blocks was measured at 2, 5 and 24 hours. 3. RESULTS The capillary water absorption versus time is presented in Table 1. |

 |
||||||||
| The results show that the inclusions of Block Emulsion reduces the capillary water absorption from 7.7% to 0.7% by mass. This represents an overall reduction of water absorbtion of 90%.
