Compressive strength, mechanical properties, residues, sustainability


In San Antonio de los Cobres located to the west of Salta, Argentine, the residents resort to the use of Adobe bricks to build their houses. Such masonry is made by the residents themselves using old building techniques whose principal material is clay. At present, this material turns out to be scarce in the region due to the growing demand. On the other hand, in the vicinity of the town, there are mining plants which extract perlite generating wastes of particles smaller than 150 microns. With a high-content of residues (70% by weight), raw solid bricks are elaborated with a CINVA-Ram compacting unit. The aim of the present research work is to analyze the possibility of replacing Adobe bricks with these new bricks. Such analyses will follow tests which comply with IRAM standards (official national standards body for the Republic of Argentine), such as compression and flexion strength, absorption, capillary absorption and thermal conductivity tests. In conclusion, our results indicated that raw-perlite brick studied had better physical properties than the Adobe bricks.
