With this issue (Volume 8 Number 1, February 2015), we open the eighth volume of the IBRACON Structures and Materials Journal. This issue contains five articles related to concrete structures and materials. The first article presents an application of Chapelle's method for determining the reactivity of pozzolanic materials. The method is applied to evaluate lime consumption by metakaolin, silica fume, fly ash, sugar cane bagasse ash and rice husk ash, comparing the result with mass proportions - lime:pozzolan 1:1, as originally proposed by Chapelle, and 2:1 according to Brazilian and French Standards. The second article evaluates the effect of polypropylene and steel fibers on the loss of water by evaporation and shrinkage of concrete. A study was carried out to relate the loss of water from the paste and the shrinkage during the first 28 days of age, using a control mix without fiber for comparison. Another article aims to evaluate the use of coal waste to produce concrete paving blocks. A process was developed with the purpose of reducing the sulfur content of the coal waste and changing the particle size distribution to meet the specifications for fine aggregates. The fourth article discusses the implementation and validation of a software for thermal analysis of two-dimensional structures subjected to fire. The last article discusses an anisotropic damage model for analysis of reinforced concrete structures submitted to reversal loading.
We congratulate the authors for the quality of the published articles and acknowledge the dedication of the reviewers.
