Abstract
In Brazil, ceramic blocks have a significant share of the masonry construction market. Thus, an experimental testing program was devised to determine the physical and mechanical properties of ceramic blocks from different regions of Brazil. The experimental program included blocks from five Brazilian states and ten different producers, and the properties studied were absorption, material density, efflorescence, abrasion, compressive strength, and resistance towet-dry cycles. The purpose of determining these material properties is to set guidelines to standardize the performance of same-geometry blocks. The material density test method and the wet- and dry cycle test method are being proposed as new tests and are not usually specified in international codes. The objective of the wet and dry cycle test is to determine a durability parameter for blocks that are not subjected to freeze-thaw cycles. The analysis of the results identified important relationship between these properties. Keywords: masonry, clay, ceramic blocks, test in blocks.
Highlights
There are several applications of ceramic materials: from science to technology, to industry [1,2,3]
Industrial application includes the manufacturing of ceramic blocks for use in masonry, which represents 80% of masonry construction in Brazil [4]
The following section presents the results from the tests and a discussion highlighting the results that can be used consistently to characterize Brazilian ceramic blocks
Summary
There are several applications of ceramic materials: from science to technology, to industry [1,2,3]. Industrial application includes the manufacturing of ceramic blocks for use in masonry, which represents 80% of masonry construction in Brazil [4]. Structural masonry has been proved to be a competitive building system for housing construction throughout Brazil [5]. Structural masonry construction has several advantages, the main one being the fact that one element, masonry, fulfills several functions [6]. Another advantage of masonry is its durability, obtained from the proper selection of materials [7]. The main masonry element is either a concrete or a ceramic block; ceramic blocks are produced with fine-grained, non-metallic, and inorganic iron or alkali rich clays
