Alvenaria estrutural de blocos de concreto celular autoclavado e blocos de concreto - influência da junta vertical na resistência à compressão de prismas

Abstract

The mechanical properties to the compression of the masonry are basic parameters used in design of structural masonry and they are generally evaluated from prism tests. This work describes the study of the mechanical behavior of autoclaved cellular concrete and concrete blocks prisms, without grout, and vertical joint, with filled vertical joint, and with non-filled vertical joint, subjected to the loading of the axial compression. Then it was performed experimental tests and statistical analysis of the results. It was employed on this work autoclaved cellular concrete blocks that were made and used in the state of Minas Gerais by SICAL company. The dimensions of these blocks are 60 cm length, 30 cm height, and 12,5 cm width. The dimensions of the concrete blocks are 40 cm length, 20 cm height, and 10 cm width. The prisms configurations proposed are according to the American code ASTM-E-447 Compressive Length of Prisms, which describes a possible fail process as they are subjected to loading axial compression.
