Resumen

VISAIRO-MENDEZ, R.; TORRES-ACOSTA, A. A.  y  ALVARADO-CARDENAS, R.. Specimen size effect on the durability indexes determination for cement-based materials. Rev. ALCONPAT [online]. 2019, vol.9, n.3, pp.288-302.  Epub 26-Jun-2020. ISSN 2007-6835.  https://doi.org/10.21041/ra.v9i3.381.

In this project is required to determine if there is any result variation in durability indexes due to size effect in sizes of mortar specimens. Cubes 5 x 5 cm, 5 x 10 cm and 10 x 20 cm cylinders for each mortar type were considered. It was found that in certain indexes (WER, TVC, and CS) results did not depend on specimen´s geometry. Nonetheless, UPV index result presented differences up to 17.5 % between the cubes and the 10 x 20 cm cylinders. εeff index result showed an interesting difference between the cubes and the 5 x 10 cm cylinders used in full length. Therefore, it is recommended to restrict the height of the specimen to a standard value.

Palabras llave : mortar; durability; size; performance.
