Performance of recycled concretes exposed to sulphate soil for 10 years
(Elsevier, 2016-01)
Recycled aggregate concretes, particularly those made with crushed concrete in replacement of the natural coarse aggregate, have been increasingly used in the last decades. Although compressive strength is not affected by ...
External sulphate attack on recycled concrete: Assessment of the influence of recycled aggregate
(Springer, 2020)
The performance of recycled aggregate concrete (RAC) under external sulfate attack (ESA) has not been fully clarified yet. The attached mortar on recycled aggregate particles increases the content of hydration products ...
Diagnosis and rehabilitation possibilities of real reinforced concrete structure
(PONTIFICIA UNIV CATOLICA CHILE, ESCUELA CONSTRUCCION CIVIL, 2008)
A diagnosis and rehabilitation study of a reinforced concrete structure is presented in this paper. The Public building was corstructed in 1939, located in marine environment, distant less than I km of the coastal border, ...
Electrochemical behaviour of heat-treated Al-Zn-Mg alloys in chloride solutions containing sulphate
(Elsevier B.V., 2002-07-05)
The electrochemical corrosion and passivation of Al-5Zn-1.7Mg-0.23Cu-0.053Nb alloys, submitted to different heat treatments (cold-rolled, annealed, quenched and aged, and quenched in two steps and aged), in sulphate-containing ...

Diagnosis and rehabilitation of real reinforced concrete structures in coastal areas
(MANEY PUBLISHING, 2012)
A diagnosis and rehabilitation study of two reinforced concrete structures located in coastal areas in two different climates is presented. Building 1 was constructed in the north of Chile in 1949, at a distance of 600 m ...
Long-term sulfate attack on recycled aggregate concrete immersed in sodium sulfate solution for 10 yearsAtaque por sulfatos a largo plazo sobre hormigón de árido reciclado sumergido en solución de sulfato de sodio por 10 años
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2020-02)
The effect of recycled concrete aggregate (RCA) on concrete performance against external sulfate attack (ESA) is not yet fully known. In this paper, recycled aggregate concretes (RAC) with 0, 50, 75 and 100% of RCA contents ...
