Compacted or rammed earth is an ancestral building construction material, which may or may not be stabilized using chemical additives such as cement or lime. Raw earth varies from region to region and any cohesive earth can be used to build earthen constructions. Clayey earths can be used in adobe, while sandy earths are suitable for the compressed earth block technique. For the case of rammed earth, a well graded soil containing clay, silt, sand and gravel is suitable. Though grain size is the significant factor, for which, Houben and Guillaud (Traité de construction en terre. Editions Parenthèses, Marseille, pp. 404–405, 1995 [1]) established a well-known spindle for rammed earth, factors such as plasticity of fine fraction influences physico-mechanical behavior of rammed earth. In this context, the present study explored experimentally, the suitability of stone dust debris which is a waste by-product during the processing of manufactured sand and construction debris as an admixture to manufacture rammed earth using locally available cohesive soil. Three formulations were used in the study that lead to increase in dry density and decrease in optimum moisture content leading to ecological advantage. The mix configurations used in the experimental study conclusively establishes the suitability of both the waste by-products as a sustainable admixture that reduces plasticity index, affects shrinkage volume and increases compressive strength to the desired level at which the manufactured rammed earth will be suitable as a sustainable construction material.
