Evaluation of the effect of varying the workability in concrete pore structure by using X-ray microtomography

Autor: E. E. Bernardes, A. G. de Magalhães, W. L. Vasconcelos, E. H. M. Nunes

Publikováno v: Revista IBRACON de Estruturas e Materiais, Vol 6, Iss 4, Pp 582-597

The useful life of concrete is associated with the penetrative ability of aggressive agents on their structures. Structural parameters such as porosity, pore distribution and connectivity have great influence on the properties of mass transport in po

Monitoring the carbonation front progress in a cementitious composite having its pore structure analyzed through μ-CT imaging

Autor: E. LACERDA, A.G. MAGALHÃES, E.E. BERNARDES, E. H. M. NUNES, W.L. VASCONCELOS

Publikováno v: Revista IBRACON de Estruturas e Materiais, Vol 10, Iss 3, Pp 653-668

ABSTRACT The carbonation process is one of the factors that cause a reduction in the hydrogenionic potential (pH) in cementitious composites, which can lead to a depassivation of the reinforcement structures, thus furnishing conditions for a corrosio

Characterization of test specimens produced in reduced size for X-ray microtomography (µ-CT) tests

Autor: E. E. BERNARDES, A. G. DE MAGALHÃES, W. L. VASCONCELOS, E. V. M. CARRASCO, E. H. M. NUNES, L. B. DE LIMA

Publikováno v: Revista IBRACON de Estruturas e Materiais, Vol 10, Iss 5, Pp 1025-1041

Abstract The need to use reduced sample sizes, in order to attain improved spatial resolution in (µ-CT) tests applied in Portland cement composites, makes researchers perform the fractionation of materials to obtain samples with dimensions compatibl
