Stress-strain characteristics of concrete containing quarry rock dust as partial replacement of sand
The paper presents results of study on concrete using quarry dust to replace sand at levels of 0%, 25%, and 100% by weight. Design mixes were prepared to achieve concrete grades C25, C30, C35, C40 and C45 for each of the three replacement levels. Prismatic specimens were prepared to study the stress...
