Abstract

The objective of this project is to research and develop a construction process using panels of prefabricated armed concrete reinforced with expanded polystyrene core for use in one-storey houses. The work includes the evaluation of performance with regard to compliance with the regulations laid down by law in Norm CE 02.136.01, of the Brazilian Association of Technical Norms (ABNT) for buildings of up to five stories. The viability study to be undertaken in phase 1 of the project, involves the stages of data gathering/theoretical analysis of the performance of the proposed construction process; analysis and evaluation of the existing interfaces; study of the dosage of concrete to be used in the make-up of the panels; creation of a base-architectonic design; manufacture of the panels and assembly of the prototype; performance trials and their respective evaluation; and, finally, evaluation of the technico-economic viability of the proposed construction process. The appropriate development of a construction technology such as this has many technical contributions to give to the sector, such as the consolidation of prefabricated construction methods and processes; the introduction of industrialized construction techniques which increase productivity and the quality of the buildings; and the supplying of a finished product that offers guarantees, decreasing the high incidence of pathologies in buildings.
