An Effective Replacement of Granite and Marble Powder on Cement Mortar Subjected to Chloride Ion Penetration Test

Many researches has been carried out regarding the possible reuse of the waste materials like marble and granite powder in a economical and eco-friendly manner. The use of marble and granite products waste is identified as a substitute to cement in mortar mix to an option that come up with concrete products in a cheaper cost in the construction industry. In the sustainable point of view, an experimental study is conducted on the cement mortar with the replacement ratio of 0%, 5%, 10%, 15%, 20%, 25% and 30% of marble powder and granite powder in the cement content to examine the durability properties. For this durability study, the mortar disc specimens of dimensions 80 mm × 50 mm are prepared, cured for a period of 28 days and tested for rapid chloride permeability test. The experimental results are showing that the granite powder replaced mortar is moderately better than marble powder replaced mortar. The optimum replacement is found as 5% for marble dust and 10% for granite powder, since the penetration is low based on the experimental results.
