摘要：
The present work studies the bond strength between new mortars and old tiles. The influence in tile/mortar bond strength of moisture content of tiles, mortars aggregates grain size distribution and nature, binder/aggregate ratio, different tile ceramic parts, water absorption and porous characteristics of historic tiles and new mortars were evaluated. Laboratory bond strength tests were performed with 6 different types of old tiles and it were performed 3 bond strength tests in situ. Tile/mortar bond strength values rise with an increased moisture content on tile. Most presented mortar compositions are suitable for reapplication of historic tiles as they present bond strength values (approximate to 0,04 MPa-0,10 MPa) similar to in-situ tests.
