Elementos Pré-Moldados: Fabricação e Aplicação de Blocos de Concreto Pré-Moldados em Alvenaria Estrutural

Abstract

application practices and reduction in the execution time of the work. With the pre-cast series production, quality control becomes more efficient, thus ensuring the minimum requirements set out in regulatory standards. An example of an element with its series production is the precast concrete block of structural masonry, where its manufacture is made in production line with semi-automatic and automatic machines. The advantages of the precast elements in a civil construction work are very broad, where in a project that is necessary the short execution time, these elements are highly recommended. This work aims to know the precast elements and to cover the manufacturing and application processes of the precast concrete blocks of structural masonry, in addition to addressing the advantages and disadvantages of its use in the construction processes. The method is based on technical articles, books that have widely reported the origin, manufacture and application of the precast. For structural masonry approach, we rely on scientific articles and regulatory standards that define manufacturing methods, quality and final application. We monitor the fabrication and application of the precast elements, focusing on the precast concrete blocks of structural masonry according to their classes A, B and C. The results obtained with the application of structural masonry in place of the conventional are notorious because it reduces the need for other elements of structural reinforcement, such as beams and pillars of reinforced concrete, in the construction of a work, applying the structural masonry and taking into account the design to be designed, in this way, it is used only the precast concrete blocks of structural masonry, mortar, grate and hardware. We conclude that prefabricated materials are already in the middle of the building process of building for a long time and that is really a process that is renewed with the passage of time, and is increasingly present in the day-to-day works, bringing reduction at the time of execution, cleaning and organization at the construction site and reducing the use of other structures used in conventional processes, ensuring the same safety, stability, durability and comfort.
