摘要

Researches in green building materials consist of developing alternatives to traditional materials or processes that offerenvironmental advantages. This paper presents an experimental investigation performed on new green and ecological blocksbased on gypsum plaster and desert sand mortar. The first part of this experimental investigation focuses on the incorporationof desert sand, with different proportions, in the plaster matrix. For this, different cubic and cylindrical specimens wereprepared by adding 0, 20, 30, 40, 50, 60, 70 or 80% sand to the mixture. Thereafter, physical and mechanical propertiesof mixtures, such as density, absorption, hydration temperature, and compressive strength, were investigated. The resultsshowed that the incorporation of desert sand has significantly improved the properties of sand–plaster mortar compared tothose of plaster mortar. The second part of this study consists of studying new ecological blocks manufactured from theoptimal mixture, 50% sand + 50% plaster. The results carried out on prototypes of the new blocks give to this new block theopportunity to be used as insulated building materials for the construction of interior walls.
