Permeability properties of self-compacting rubberized concretes
چکیده انگلیسی

The paper presented herein was carried out to investigate the permeability characteristics of self-compacting rubberized concretes with and without fly ash. At a water–cementitious material (w/cm) ratio of 0.35, the self-compacting concretes (SCCs) were produced by replacing the fine aggregate with four designated crump rubber contents of 0%, 5%, 15%, and 25% by fine aggregate volume. Moreover, the SCCs with fly ash were produced by partial substitution of cement with fly ash at varying amounts of 20% to 60%. Totally, 16 concrete mixtures were cast and tested for permeability related properties such as chloride ion permeability, water sorptivity, and water absorption. The tests were conducted at 28 and 90 days after casting. Tests results revealed that using the crumb rubber aggravated all of the measured properties of self-compacting rubberized concretes (SCRCs) without fly ash. However, with the combined use of the crump rubber and fly ash, the concretes had better resistance to the chloride ion permeability, water sorptivity, and water absorption.


► Utilization of crump rubber in the production of self compacting concretes.
► Using the crumb rubber aggravated the properties of SCRCs without fly ash.
► Crumb rubber aggravated all of the measured properties of SCRCs without fly ash.
► Using of crump rubber with fly ash provided higher permeability resistance.
► Longer curing period decreases ingress of chloride ions.
