Se confeccionaron probetas cilíndricas sobre las que fue evaluada la resistividad mediante el método de la sonda de Wenner. Comparando los resultados obtenidos con los valores umbrales indicados en la literatura, se permite entender la importancia que frente a este mecanismo de degradación implica limitar a 0.45 la máxima relación a/c. Por otra parte, el cemento CPP resultó ser el de mejor desempeño, dando lugar a mayores resultados de resistividad, mientras que la incorporación del hidrófugo tuvo un efecto de nulo a contraproducente en dicho parámetro.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In the present work it is evaluated how the variation of the water/cement ratio influences the electrical resistivity of the concrete; the type of cement selected (CPP and CPF); and the incorporation of a water repellent. Cylindrical specimens were made on which the resistivity was evaluated using the Wenner probe method. Comparing the results obtained with the threshold values indicated in the literature, it is possible to understand the importance of this degradation mechanism that implies limiting the maximum w/c ratio to 0.45. On the other hand, the CPP cement turned out to be the one with the best performance, giving rise to higher resistivity results, while the incorporation of the water repellent had a null or counterproductive effect on said parameter.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo No presente trabalho avalia-se como a variação da relação água/cimento influencia na resistividade elétrica do concreto; o tipo de cimento selecionado (CPP e CPF); e a incorporação de um impermeabilizante à massa de concreto. Corpos de prova cilíndricos foram feitos nos quais a resistividade foi avaliada usando o método da sonda de Wenner. Comparando os resultados obtidos com os valores limites da literatura, foi possível perceber a importância de limitar a relação água cimento em 0,45, para aumentar a resistividade do concreto acima de certos limites consagrados. Por outro lado, o cimento CPP (pozolânico) revelou-se o que apresentou melhor desempenho, originando resultados de resistividade mais elevados, enquanto a incorporação do impermeabilizante de massa teve um efeito nulo ou contraproducente neste parâmetro.]]></p></abstract>
