Abstract


Stones placates present a wide of problems that result in the fall of plates. One of the causes is the lack of adherence stone-mortar.
We considered a study to determine the adherence between several cement mortars (1:3, 1:5, 1:7, 1:9 and a especial mortar prepared with latex) and stones (white granite, pink granites, black granites, white marble and cream limestones).
The results obtained suggest that only adequate adherence rates (higher than 3 kgf/cm2) achieved with cement mortar 1:3 and especial mortar.
Besides it is observed that in the stones studied there is no relation between adherence and the absorption values.
