Abstract
Current article reviews the results of various research studies which were carried out in the recent past to investigate the compressive strength of concrete containing Waste Marble Powder (MP) and metakaolin (MK) as a replacement of fine aggregates and cement. A number of research studies were reviewed to check the potential of MP and MK as partial replacement of fine aggregates and Portland cement respectively. Various researchers replaced the fine aggregates in the range of 0–50% with MP reported the increase in compressive strength, however beyond 20% replacement the strength properties went on decreasing. Consequently most of the research studies reported that Portland cement was replaced with the MK in the range of 0–20%. The strength enhancement reported from 7 to 15% replacement levels of MK with Portland cement beyond that replacement level of MK their existed adverse effect on strength properties of concrete. The potential of these two by-products (MK and MP) has not been fully explored yet and still a number of properties can be investigated and improved by replacing them with fine aggregates and cement in different percentages and types.
