The measurements carried out were apparent speed of ultrasonic pulse, electrical resistivity, fast ion permeability of chloride and mechanical resistance to compression. The performance of all mixtures proved to be durable, and the development of the electrical resistivity and the decrease in the level of the chloride ion permeability were enhanced by the contents of AFA, although the resistance to compression at higher contents of AFA was minor. The maximum percentage of AFA to comply with the current criteria of durability was 65%.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Este artículo describe propiedades referentes a la durabilidad de cinco mezclas de concreto con distintos contenidos de ceniza volante activada (CVA) y cemento portland tipo CPC 40. Los ensayos realizados fueron: velocidad de pulso ultrasónico, resistividad eléctrica aparente, permeabilidad rápida al ión cloruro y resistencia mecánica a la compresión. Los resultados indicaron que la calidad de todas las mezclas resultó durable, el desarrollo de la resistividad eléctrica y disminución del nivel de permeabilidad al ión cloruro fue favorecido por el contenido de CVA. En cuanto a las resistencias a la compresión, se notó que a mayor contenido de CVA estas resultaron menores. El porcentaje máximo de sustitución de CVA para cumplir con los criterios de durabilidad actuales resultó del 65%.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Este artigo descreve propriedades relativas à durabilidade de cinco misturas de concreto com diferentes teores de cinzas volantes ativadas (CVA) e cimento portland tipo CPC 40. Os ensaios realizados foram: velocidade de pulso ultrassônico, resistividade elétrica aparente, permeabilidade rápida ao íon cloreto e resistência mecânica à compressão. A qualidade de todas as misturas foi duradoura, o desenvolvimento da resistividade elétrica e a diminuição do nível de permeabilidade ao íon cloreto foi favorecido pelo conteúdo de CVA, embora a resistência à compressão em maior conteúdo de CVA tenha sido menor. O percentual máximo de substituição do CVA para atender aos critérios atuais de durabilidade foi de 65%.]]></p></abstract>
