PHYSICAL-CHEMICAL CHARACTERIZATION OF THE MAIN CERAMIC BLOCKS AND SMALL AGGREGATES MARKETED IN THE PETROLINA AND JUAZEIRO RIDE

Abstract

Masonry degradation is caused by numerous causes, which are derived from pathological processes with active and/or passive agents. Among these, the deposit of soluble salts on the surfaces of the structures, called efflorescence, is a serious problem in the buildings of the Petrolina-PE and Juazeiro-BA Integrated Economic Development Region. Therefore, this study aimed to evaluate the physical, physicochemical and chemical characteristics of the main ceramic blocks and small aggregates sold in this region. The experiment was a completely randomized design with four treatments and six replications for the ceramic blocks and nine treatments and six replications for the small aggregates. The results of this work allowed the identification of building materials with greater potential for efflorescence formation in sealing and structural masonry. In addition, the determination of the physical characteristics of small aggregates will allow professionals in the region to access more accurate information for the correct rational dosage of mortars and concretes since the modulus of fineness and specific mass are important parameters in this case.
