Reviewers
Reviewers are selected by the Editors among the IBRACON members with recognized competence in the specific field of each contribution. They are acknowledged at the end of each volume.
We are now releasing the third issue of the second volume of our IBRACON Structures and Materials Journal (Vol. 2 Num. 3). In this issue the influence of moderate temperatures on the mechanical behavior of lightweight concrete is addressed, focusing on the use of waste from the shoes industry (EVA) and from construction and demolition (CDW). The second article deals with the analytical solution to simulate the structural behavior of reinforced concrete beams post-strengthened with FRP strips. The third article addresses concretes with very high amount of fly ash and slag, with the objective of improving sustainability. The fourth article deals with the development of high performance hybrid cement composites. The last article addresses the use of health monitoring techniques to investigate creep behavior of commercial concrete specimens.
The papers have been carefully reviewed by the Editorial Board and highly qualified reviewers from Brazil and from abroad. We acknowledge the reviewers' contribution, fundamental for the publication of our Journal. We congratulate the authors of the papers presented in this issue. Again we invite all the concrete community in Brazil and abroad to participate in the activities of the IBRACON Structures and Materials Journal, as a frequent reader or as a contributor. Os artigos foram examinados pelo Comitê Editorial e revisores nacionais e estrangeiros do mais alto nível técnico. Agradecemos aos revisores que nos apoiaram, sem o quais não seria possível a publicação de nossa revista. Parabenizamos os autores dos trabalhos apresentados neste número, destacando o esforço que vem sendo realizado para a manutenção da alta qualidade de nossa revista. Aproveitamos a oportunidade para renovar nosso convite a todos para que participem da Revista IBRACON de Estruturas e Materiais, ou como leitor assíduo ou como autor.

Aims and Scope
The IBRACON Structures and Materials Journal is a technical and scientifical divulgation vehicle of IBRACON (Brazilian Concrete Institute). Each issue of the periodical has 5 to 8 papers and, possibly, a technical note and/or a technical discussion regarding a previously published paper. All contributions are reviewed and approved by reviewers with recognized scientific competence in the area.

Objectives
The IBRACON Structures and Materials Journal´s main objectives are: • Present current developments and advances in the area of concrete structures and materials; • Make possible the better understanding of structural concrete behavior, supplying subsidies for a continuous interaction among researchers, producers and users; • Stimulate the development of scientific and technological research in the areas of concrete structures and materials, through papers peer-reviewed by a qualified Editorial Board; • Promote the interaction among researchers, constructors and users of concrete structures and materials and the development of Civil Construction; • Provide a vehicle of communication of high technical level for researchers and designers in the areas of concrete structures and materials.

Submission Procedure
The procedure to submit and revise the contributions, as well as the formats, are detailed on IBRACON's WebSite (www.ibracon.org.br). The papers and the technical notes are revised by at least three reviewers indicated by the editors. The discussions and replies are accepted for publication after a revision by the editors and at least one member of the Editorial Board. In case of disagreement between the reviewer and the authors, the contribution will be sent to a specialist in the area, not necessarily linked to the Editorial Board.

Contribution Types
The periodical will publish original papers, short technical notes and paper discussions. Announcements of conferences and meetings, information about book reviews, events and contributions related to the area will also be available in the periodical's WebSite. All contributions will be revised and only published after the Editorial and Reviewers Boards approve the paper. Restrictions of content and space (size) are imposed to the papers. The contributions will be accepted for review in Portuguese, Spanish or English. The abstracts are presented in Portuguese or Spanish, and in English, independently of the language in which the paper is written. After the review process, papers originally written in Portuguese or Spanish should be translated into English, which is the official language of the IBRACON Structures and Materials Journal. Optionally, papers are also published in Portuguese or Spanish.
Original papers will be accepted as long as they are in accordance with the objectives of the periodical and present quality of information and presentation. The instructions to submit a paper are detailed in the template (available on IBRACON's WebSite).
The length of the papers must not exceed 20 pages.
A technical note is a brief manuscript. It may present a new feature of research, development or technological application in the areas of Concrete Structures and Materials, and Civil Construction. This is an opportunity to be used by industries, companies, universities, institutions of research, researchers and professionals willing to promote their works and products under development. The instructions to submit a technical note are detailed on IBRACON's WebSite.
A discussion is received no later than 3 months after the publication of the paper or technical note. The instructions to submit a discussion are detailed on IBRACON's WebSite. The discussion must be limited to the topic addressed in the published paper and must not be offensive. The right of reply is guaranteed to the Authors. The discussions and the replies are published in the subsequent issues of the periodical.

Subscription rate
All IBRACON members have free access to the periodical contents through the Internet. Non-members have limited access to the published material, but are able to purchase isolated issues through the Internet. The financial resources for the periodical´s support are provided by IBRACON and by research funding agencies. The periodical will not receive any type of private advertisement that can jeopardize the credibility of the publication.
