| Popis: |
The paper presents results of an experimental research made upon the self-sealing of a fibre reinforced mortar with an integral crystalline waterproofing admixture in a dosage rate of 1-3 % of the cement mass. Samples were pre-loaded in three point bending up to 90 % of the ultimate capacity and conditioned in wet-dry cycles. Micro-cracks width was measured with a microscope after pre-loading, and up to 20 days. The results show that the 3 % admixture content presents the superior self-sealing performance both in the terms of the self-sealing degree and self-sealing rate. According to the results, lower contents of crystal-line admixture cannot predict a desirable self-sealing target, despite the fact that the self-sealing potential/ability is indisputable and may take longer periods. |
