Variation of Absorption in raw perlite bricks

Abstract

Raw perlite bricks present an option for the use of raw perlite waste generated in the puna area in the province of Salta, since they present compressive strengths greater than 5 Mpa 90 days after their manufacture and they can be used for the manufacture of social housing. Despite this, it has a high absorption percentage with respect to its weight, around 20%. This is due to the fact that its manufacture is carried out with manual compaction without requiring electrical energy. Beyond the fact that this masonry is intended for desert climate areas, different types of waterproof coatings will be analyzed, following the IRAM 12588 Standard, to compare the variability of absorption versus the cost and quality of the waterproof material.
