Construction　technology　in　the　twenty-first　century　is　on　the　peak　yet　developing　countries　of　the　world　still　dream　for　shelter　in　bad　weather　conditions　and　apply　old　traditional　techniques　for　construction　of　their　houses.　The　reason　is　the　increasing　cost　of　construction　materials　due　to　energy　crises,　poor　economic　conditions,　and　sometimes　the　love　of　people　toward　earthen　architecture　culture.　The　world　will　prefer　low　energy　alternatives　to　conventional　construction.　Some　alternatives　regarding　conventional　construction　like　mud　block　masonry　are　part　of　this　research　paper　to　avoid　shrinking　natural　resources　and　take　control　of　the　energy　crisis.　This　research　work　focuses　on　the　compressive　strength　of　the　mud　block　by　stabilizing　it　with　additives　like　waste　gypsum.　The　study　also　intended　to　investigate　the　rapid　hardening　of　the　masonry　block.　Finally,　study　the　morphology　of　the　stabilized　blocks　by　using　scanning　electron　microscopy　and　energy　dispersive　X-ray　microanalysis　(EDXMA).　This　research　found　that　the　compressive　strength　of　waste　gypsum-stabilized　mud　block　at　7　days　and　14　days　increases　with　the　increasing　rate　of　waste　gypsum　from　0　to　20%.　This　research　will　help　the　poor　community　by　reducing　the　economy　and　energy　consumed　in　the　construction　of　houses.　Besides,　this　research　will　play　a　role　by　minimizing　the　consumption　of　natural　resources,　encourage　people　to　reuse　waste　gypsum　in　construction　without　compromising　on　environmental　pollution.
