ABSTRACT

The work on High Adhesive-Polymer Cement Concrete, HA-PCC is already under way. The PCC with adhesion bond (pull of test) around 5 MPa has been received till now. It is worth to stress that High Strength Concrete need-by nature-more aggressive surface preparation, which could result-in turn-in the increase of microcracks in concrete substrate. In such case “bonding layer” on concrete substrate below the repair materials will be justified or even needed. The repair materials-as the rule-should contain microfibers for better “microcrack bridging”. There is a need not only for new generation of repair materials but also for new generation of repair systems and methods.
