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/cm 2 ) 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.

En varios edificios visitados en Cádiz, Huelva y Sevilla, una serie de problemas importantes cuya consecuencia más inmediata es el rechazo incipiente al uso de la piedra como aplacado
Summary
We considered a study to determine the adherence between several cement mortars (1:3, 1:5, 1:7, 1:9 and a especial moriar prepared with latex) and stones (white granite, pink granites, black granites, white marble and cream limestones). El empleo de piedra natural como revestimiento exterior ha supuesto una mejora en las características generales del edificio ya que estos materiales incrementan el aislamiento térmico y acústico además de ser más resistentes que los tradicionales ante la acción de los agentes externos, con lo que se aumenta la durabilidad de la fachada. En varios edificios visitados en Cádiz, Huelva y Sevilla, una serie de problemas importantes cuya consecuencia más inmediata es el rechazo incipiente al uso de la piedra como aplacado.
