[en] This paper investigates the mechanical properties of a self-compacting concrete reinforced with steel fibres (HACFRA),especially the tensile strength, and their evolution in time in comparison with a conventional concrete structure. Mechanical tests were performed on that concrete on the 7th ,14th ,28th, 90th and 365th day to evaluate the compressive strength, the flexural strength and the indirect tensile strength.
[en] The objective of the developed work is to analyze an autocompacting concrete through the Schmidt Hammer trying to analyze the relation between sclerometric index, resistance achieved by the compression test and time.
[en] In the video game and animation film industries, design techniques are used to facilitate the preview of complex architectures, buildings, and backgrounds. These can include both organic and inorganic forms. Within the workflows of these industries, 2D and 3D digital tools and software are used, as we mentioned in the communication carried out in the international congress on building APEGA 2019
[en] Sustainability means improving the standard of living according to the carrying capacity of the natural and urban environment. Sustainability implies the consumption of resources that does not exceed the capacity of nature to replace them, addresses the maintenance of biodiversity, health and quality of life in the future.
[en] The development of Building Information Modelling (BIM) in recent years has required great efforts to adapt to adapt traditional methods to this new work methodology. In the case of intervention in architectural heritage, the use of the HBIM (Heritage BIM) is essential to optimize the limited resources available
[en] It’s possible to appreciate the negative effect of corrosion not only in steel’s bars but also in the concrete and in both materials together. It causes a cracking of the concrete and its separation, a reduction of adherence between concrete and steel but most of all a reduction of section of the bars, which causes a variation of mechanical properties related to ductility
[en] At present, we see the great advances that occur at the technological level, in all areas of daily life, and instead, as far as building is concerned, the construction methods and materials used are, practically, the same since generations. This leads us to think that, although these methods of execution work perfectly, we can adapt the technological advances that surround us to the constructive processes.
[en] This paper analyzes the differences existing in Annex 14 of Instruction EHE 08 Recommendations for the use of concrete with fibers between the quality control of conventional concrete (HC) and that of concrete reinforced with steel fibers (RCSF).
[en] The building industry is responsible for a high percentage of atmospheric emissions of greenhouse gases, with the addition of an immense amount of waste generated from the construction of buildings until demolition, with a percentage minimum recycling of said waste. Becoming a very unsustainable and highly polluting sector.
[en] The German State supports renewable energies through the Renewable Energy Sources Act (EEG). This law entered into force on April 1, 2000 and has undergone successive modifications, the last one in the year 2017. This law establishes that the operators of facilities in which only renewable energy sources are used have the right to claim the operator of the electricity network for the electricity generated in these facilities...
