The use of reforestation wood in civil construction plays an important role in the sustainable development of the world, as is the case with oriented wood strip panels. Coming from continuous technological advancement, which adds quality to the material and creates new constructive solutions, OSB (Oriented Strand Board) panels appear as an effective alternative for society. This work aims to broaden the knowledge about the use of OSB boards in the building system (CES), due to their function and application in wall, slab, roof and roof sealing, based on a case study of the construction process of a residence. in the city of Manaus. Advantages and disadvantages of this system were compared when compared to the conventional system, and its use (OSB / CES) has been shown to meet the sustainability criteria, as it is ecologically viable, being a clean, lean process; economically viable, fast, cheap and inclusive as it generates local employment. Further studies are needed to understand the importance of using clean technologies for construction, capable of reducing impacts on the environment, without compromising the development of the site.
The water treatment processes in which microorganisms act are margin filtration, slow filtration and biological activated carbon (CAB) [2]. For this research, a study of permeable concrete with the addition of 2% activated carbon for light traffic paving was performed. The objective of this research is to identify the feasibility of using this concrete so that filtered water can reach at least the basic sanitation networks, with a better quality to be treated. For this, characterizations of the quality of the concrete component materials were made with a novelty, using the fine aggregate (sand). After the characterizations, the permeable concrete traces with mechanical strength of 30MPa were made. Dosing analyzes followed with molding, curing and rupture of concrete specimens. The results of the arithmetic mean of the axial compression of conventional concrete at 28 days were 34.2 MPa and the concrete with the addition of activated carbon was 32.2 MPa, reaching the expectations of strength. Complementary experiments were performed for the quality of the water filtered by the CP's, the pH, the alkalinity and the chlorine content were analyzed. The pH of the conventional concrete found was 7.6 and the concrete with the addition of activated carbon was between 7.2 and 6.8, which may be the best result found
Regarding the historic squares of the city, several have reached a stage of total degradation others have disappeared or suffer from overuse or misuse. Methodology: bibliographic and field research. Revitalization deals with a series of steps that lead a given space to have new efficiency, a new sense of usability, improving its surroundings in order to provide its residents and visitors a better living and leisure space. The proposal has a modern architecture following the standards of reforms that are currently being made in all major cities of the country, among its modifications include the implementation of outdoor gym, playground, ramps designed within accessibility standards, tactile floor installation, etc. The cost of the project will be R $ 255,837.02 plus BDI rate of 23.89%, lasting 60 days for its completion.
This work of completion aimed to demonstrate the importance of the use of PPE in construction with awareness and guiding the use of personal protective equipment at the construction site area. It is estimated that the construction activity is responsible for many accidents, by requiring its employees to expose themselves to environmental hazards, such as: physical, chemical, biological, ergonomic and accidents. Considering that the Personal Protective Equipment PPE are important security items from working, since, in construction using the same becomes sporadic or non-existent on the part of service providers and employees, even if they have knowledge of the law and standards. During the study we can observe and note that the use of PPE is very important and essential in reducing the risks of accidents during the execution of the activities and their functionality, because the protection of the physical integrity and health of the employee is not isolated behavior, and these must have training and technical guidance on the appropriate use of personal protective equipment. It is understood that the lack of planning of a competent security system can cause occurrences of accidents, causing losses for low productivity and increased costs. Thus, it is evident the importance and prominence that has gained the use of PPE in construction, because this is a topic that has been evolving and requires continuous recycling of professionals in this area.
