Abstract
Introduction: This paper presents an extensive characterisation of materials and components used in non-structural masonry constructions in the region of Pernambuco, Brazil. Methods: An experimental study was carried out on a running bond of red clay prisms, of two and three ceramic blocks, with and without cement mortar coating, subjected to axial compression in order to enhance the capacity of masonry. Results and Conclusion: The experimental preliminary results indicate an increase both in the compressive load capacity of the coated prisms and in those that use coatings based on reinforced mortar, not complying with the specifications of conventional structural mortar.
Highlights
This paper presents an extensive characterisation of materials and components used in non-structural masonry constructions in the region of Pernambuco, Brazil
The occurrence of diverse accidents in buildings constructed with resistant masonry in the Region Metropolitan of Recife (RMR) has drawn the attention of the regional and national technical community to adopt measures to minimize such events
It is important to note that the coefficients of variation observed were 35% and 22%, for uncoated prisms with two and three blocks respectively, indicate that the observed values should be examined with caution
Summary
This paper presents an extensive characterisation of materials and components used in non-structural masonry constructions in the region of Pernambuco, Brazil. The occurrence of diverse accidents in buildings constructed with resistant masonry in the Region Metropolitan of Recife (RMR) has drawn the attention of the regional and national technical community to adopt measures to minimize such events This kind of masonry buildings has one of its most important characteristics, the use of non-structural units in masonry walls that will carry loading beyond its own weight. Such type of construction is found with relative frequency in under developing countries as public solutions to the housing deficit of these countries, namely in Recife, Brazil In this type of construction, nonload-bearing masonry, generally leaked ceramic blocks seated with the punctures in the horizontal line or blocks of concrete with low compressive strength (2.5 MPa) are used. One can add the rapidity in the execution, the great applicability and the low cost of producing the ceramic blocks and of concrete in the state of Pernambuco, in that occasion [ 1] as reasons for stimulating the growth of this type of building in the region
