Calcium hydrated lime was added to concrete with 50% of the cement, by weight, substituted with fly ash, with the intent of replacing some of the calcium hydroxide consumed by the pozzolanic activity. Three proportions of mixes were studied: concrete with high early strength cement (HESC), concrete with 50% HESC and 50% fly ash, and concrete with 50% HESC, 50% fly ash and an additional 20% of hydrated lime. They were then tested according to ASTM C1202, but with the application of a voltage of 30 V during 35 h. Results revealed that concretes containing fly ash and hydrated lime presented a lower accumulated charge density and coefficient of chloride diffusion than the HESC concrete used as a reference.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-20T12:19:50Z No. of bitstreams: 1 10.1061(ASCE)MT.1943-5533.0000596.pdf: 1027275 bytes, checksum: 2568cd7a937a163e2080de5ed9724cd6 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-09-09T14:44:27Z (GMT) No. of bitstreams: 1 10.1061(ASCE)MT.1943-5533.0000596.pdf: 1027275 bytes, checksum: 2568cd7a937a163e2080de5ed9724cd6 (MD5)Made available in DSpace on 2014-09-09T14:44:27Z (GMT).
