Editorial
The IBRACON Structures and Materials Journal is releasing the fourth issue of the sixth volume. In this issue, eight articles are being published on significant topics of concrete structures and materials. The first article draws on graphical means for fire design of concrete beams. Creep strains on reinforced concrete columns are addressed in the second article.
Chloride accelerated tests are the topic for the next article, focusing on the influence of silica fume, water/binder ratio and concrete cover thickness. The fourth article discusses the use of X-ray microtomography for evaluation of the effects of varying the workability of the fresh concrete, produced by the use of additives, on concrete pore structure and compression strength. Another article approaches the post-cracking behavior of blocks, prisms and mini-concrete walls reinforced with vegetal fibers. The sixth article presents a numerical analysis of prestressed hollow core slabs under long term loading. Numerical results are compared with experimental tests performed on two series of prestressed hollow core slabs. The objective of the seventh article is the analysis of the spacing between supports in the assemblage of lattice slabs.
The issue closes with an article on replacement of Portland cement by stone cutting waste and ground waste clay brick, focusing on the hydration and packing density of cement pastes.
We would like to acknowledge the dedication of authors and reviewers, responsible for the significant results achieved by the IBRACON Structures and Materials Journal. We are glad to welcome Prof. Dr. Roberto Caldas de Andrade Pinto, from the Federal University of Santa Catarina, who is participating as a new Associated Editor.
