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

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 corrosion process

X-ray microtomography (μ-CT) to analyze the pore structure of a Portland cement composite based on the selection of different regions of interest

Autor: Aldo Giuntini de Magalhães, Edgar Vladimiro Mantilla Carrasco, E. E. Bernardes, Wander L. Vasconcelos

Publikováno v: Construction and Building Materials. 95:703-709

The necessity to use reduced sample sizes, in order to achieve better spatial resolution in studies on the pore microstructure of Portland cement matrix composites, leads researchers to perform the fractionation of specimens. However, there is always
