The chemical, physical and biological conditions of the soil are extremely important to obtain satisfactory agricultural production. The no-tillage system (SPD) contributes to minimize soil loss in the crop, ensuring the stability of its aggregates by minimal soil tillage and overlapping the soil with a vegetable layer. The present work aims, through a review of available literature, to show that the no-tillage system promotes soil restructuring through the action of organic matter built by crop residues from the crop rotation process. Aiming to minimize problems in agricultural production as the beginning of the erosive process, the SPD uses conservation techniques to promote soil decompression and increase the biodiversity of the production system through the diversity of species provided by the crop rotation and succession process. Thus, the no-tillage system increases the natural fertility of the soil by decomposing organic matter and intercropping with leguminous plants that increase the concentration of nitrogen (N) in the soil. Thus, it can be concluded that SPD provides numerous short, medium and long term benefits, enabling the solution of environmental problems found in the area of agricultural production, making the system more sustainable. In this work a bibliographical revision about the theme is made.

ResumoCom a escassez de materiais sustentáveis na construção civil, verificamos a alternativa da utilização de novos experimentos, criando um novo tijolo com maior resistência e durabilidade, como a fibra vegetal que além de ser um produto sustentável e de baixo custo também pode acrescentar ótimos resultados ao seus compósitos. Este trabalho tem como objetivo, confeccionar tijolos de solo cimento com adição da fibra vegetal e analisar suas principais características físicas e mecânicas. Os materiais utilizados foram: solo, cimento e água, seus ensaios foram feitos na Universidade Presidente Antônio Carlos, a primeira etapa foi a caracterização do solo, na segunda etapa foram confeccionados os tijolos com uma prensa manual e por ultimo foram feitos os ensaios da resistência á compressão e absorção da água nos tijolos. Palavras-chave: Materiais sustentáveis; Solo-cimento; Fibra vegetal; Construção civil. AbstractWith the scarcity of materials sustainaible in civil construction, we think in the alternative of use of new experiments,to increase of resistance and durability of the brick, such as fiber Development, v. 7, n. 9, p. 01-18, e779439, 2018 ISSN 2525-3409 (CC BY 4.0) 2 vegetable what beyond to be a product sustainable and from below can also add great results to their composites. This one job has with the objective, to make bricks solo cement with addition of the fiber vegetable and analyze its main characteristics physical mechanics . The materials used were: ground, cement water, their essay were made at University Antônio Carlos, the first we got the characterization of ground, on Monday stages were made the bricks with one press manual and for last were made test gives resistance the compression and absorption in water we brick. Em matéria de meio ambiente preservar os poucos recursos é primordial para manutenção da humanidade. A construção civil, através de uma educação ambiental, busca na atualidade, estabelecer uma forma de progredir, no estudo de novos materiais sustentáveis, atendendo as necessidades da sociedade com seu baixo custo e evitando a destruição ambiental. A utilização do solo como alternativa na construção civil advém desde os primórdios da humanidade, conforme relata Mazzeo Grande (2003), aprender a manipular o solo foi muitíssimo importante para o desenvolvimento do homem que passou a sair das cavernas e fixar-se em locais mais favoráveis à sobrevivência humana. Historicamente, civilizações como os Egípcios, Babilônios, apresentavam o domínio da utilização de adobe, portanto, isto vem se desenvolvendo a mais de 4.000 anos antes de Cristo. A exploração ao meio ambiente se da, pelos impactos gerados pela produção do tijolo tradicional, colaborando para a elevação do custo devido a grande procura e pouca demanda, assim encontrar novas alternativas é um passo importante para adequar as necessidades emergentes da sociedade, coincidindo com uma maior preservação do mesmo. Esta pesquisa parte da seguinte problemática: é possível melhorar as propriedades físicas e mecânicas do tijolo solo...

The purpose of this article is to address the main functions, characteristics, and, finally, methodologies employed in road conservation services at Federal Highways, specifically on Highway BR-116 between km 207.1 and Km.306.5. The peculiarities related to conservation services will be analyzed in a comprehensive and comprehensible way, in the sense that it is possible to minimize the pathologies caused by poor road conservation, as well as avoid expenses that have always burdened the public coffers. Once a highway has been deployed, so that it can have a useful life, that is, in conditions of trafficability and safety for its users, it will require multidisciplinary operations, with resources properly allocated for that purpose, equipment and skilled labor that will play paper fundamental in the mitigation of pathologies arising from the highway's own time of use, as well as from the weather.

Reuse of waste generated by the construction has been seen as an important practice for the environment, the use of the RCC has become every day more, on account of its techniques and its results. Recycling and reusing the rubble of construction if you can promote a culture where all begin an environmental responsibility, making the works become reference to sustainability in the construction area. Besides being slightly compromised with the importance of the impacts to the environment, companies that undertake to join the RCC your profitability and decrease the impacts that will be caused to the environment. This article comes to address the types of materials that can be reused, which your classification in accordance with resolution 307/02 of CONAMA, the techniques that are needed to make the reuse of residue, what are the advantages of doing the reuse, and which impacts of this waste recycling can generate.

In the contractures and engeneer/architecture office, usually, there are big concernings to avoid interference between all the projects that comprise the edification planing. Thus, it’s necessary to do compatibilizations, that now in the days, most of the times, it’s achieved by the software autocad. Those compatibilizations are necessary, beacuse enable the reduction in the construction cost  in a way that not spend the money with new materials, manpower and rework. However, when the bim platform is used, provides a new experience, like agility in the work group to compatibilibilize with much better quality. This article have a goal to study the cases of the following projects: architecture, structure, hidrosanitary and eletric of a familiar residence program named my house my life, made by federal economic caixa, in software revit, as well as the incompatibilities identification between the projects quoted and the solutions, to make viable a new way of compatibilization to popular projects with better quality. The floor plane of the archtetonic project was inserted in revit software, to start the modeling, serving as the basis for the other projects. It was united in a fale the architectural and structural projects, and separated the hydrosanitary and eletric. The files were entered in the navisworks software to check for incompatibilities between the projects in the report.  The incompatibilities were found between electrical and hydraulic, hydraulic and structural and electrical and structural projects. Therefore, the bim platform is very necessary to identify the incompatibilities quickly and simply.

The search for constructive alternatives that are more efficient, sustainable and fast in order to increase productivity and to meet the increasing demand of the Market has been one of the great challenges for the construction industry. In order to meet this demand a new construction method known as Light Steel Framing (LSF) has been a great alternative, although it is better known in  developed countries in Brazil, its practice has been diffused and used gaining even more space in the providing a fast and quality construction. In this work a comparative analysis was performed between the Light Steel Framing system and Conventional Masonry through a project of a model house of a floor with the objective of presenting the main differentials between these constructive systems in single family homes. With the projects defined, a quantitative survey of the materials used is done and the compositions of the main elements that differ between both systems are assembled. Through the surveys it was possible to identify the unit costs of each item and to carry out an analysis of the results obtained highlighting the main differences. The results showed that the LSF system presents as an industrialized system presenting higher productivity, having a clean, dry, and sustainable construction, besides presenting low weight, however, in relation to the cost of the work, the study presented the LSF system as less advantageous when compared to conventional masonry, presenting 18,09% more expensive. Knowing that the Light Steel Framing system has so many technical advantages with greater feasibility of execution over the conventional masonry system already proven with this study, it is concluded that professionals in the field of construction should encourage more entrepreneurs and contractor to use this type of construction.

Este estudo tem a finalidade de demonstrar a importância do gerenciamento dos resíduos sólidos oriundos da construção civil, expor a importância do Plano de Gerenciamento de resíduos sólidos e apresentar os benefícios e vantagens do Plano de Gerenciamento de resíduos sólidos para a obra, uma vez que, o setor da construção civil gera toneladas de Resíduos Sólidos todos os anos, onde a grande maioria destes resíduos são descartados de forma inadequada e sem preocupação com o meio ambiente. Além da produção exacerbada e exorbitante dos resíduos, existe ainda o aumento no custo dos materiais pela falta de gerenciamento destes, o que gera desperdício, conseqüentemente, despejo e acúmulo de resíduos sólidos na natureza. A realização da pesquisa foi feita através da realização da revisão bibliográfica em autores que já discorrem e pesquisaram sobre o tema. Concluiu-se ao final da escrita, que a implantação do Plano de Gerenciamento de Resíduos da Construção Civil, é perfeitamente viável para a construção civil e os benefícios vão de uma redução de 50% a 96% na geração de resíduos sólidos por mês nas obras de construção civil. Isto representa ganhos para a empresa e para o meio ambiente.
