EFFECTIVE UNFIRED CLAY BRICKS WITH NATURAL ADDITIVES
The aim of this work is to study and test new compositions of unfired clay bricks with wool as an additive for safe, sustainable, and eco-friendly natural material for building constructions. The motivations behind choosing clay as the topic of study are: its abundant existence and the possibility to enhance its thermal and mechanical properties with the lower costs possible. Besides, the possibility to add additives and stabilizers instead of drying them using firing methods. Formerly, a research conducted by our team showed that wool addition increased thermal efficiency and thermal isolation of the bricks. In addition, one example of the captivating results is that the thermal conductivity of one sample, with five % wool, was (0.19 W/m.K) . As a succession to previous work done, this work is about the enhancement of mechanical properties of unfired clay bricks especially the testing for compressive strength of the bricks, in order to evaluate their mechanical performance.
