The aim of this work is to improve the high performance mud bricks. latter was reinforced with rice straws as stabiliser leading an improvement physico-mechanical properties. Thus, physical characteristics clay such natural water content, density, atterberg limit, plasticity limit (Wp) and index (Ip) were determined. Their values are respectively 8.39%, 2025.73 Kg/m3, 47.66%, 29.75% 17.91%. use...
