Popis: This paper presents an experimental investigation into product based research, in preparation of stabilized adobe blocks (SAB) by attempting to utilize construction and demolition waste (CDW) in the form of excavated natural soil (NS) and crushed demolished brick masonry. SAB are energy efficient sustainable variety of masonry units. A detailed study on strength, durability and elastic properties of SAB produced in different combinations were carried out, to determine the optimum combination and gradation, to achieve the required engineering properties. The experimental results were evidenced at a micro-level through microstructure analysis using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). When excavated natural soil was replaced in the order of 60–80% by crushed demolition brick masonry waste, the test results indicated better strength and durability characteristics. The experimental program indicates suitability and potential of utilizing crushed demolished brick masonry waste as partial replacement to excavated natural soil in preparation of stabilized adobe blocks. This attempt of experimental research studying performance of masonry units is one of the ways to address the disposal of construction and demolition waste.
