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.

This study presents findings related to chloride permeability of several widely used Texas Department of Transportation bridge deck concrete mixtures. The rapid chloride permeability test (RCPT) was selected and seven mix designs were tested; five were evaluated using cores taken from field-cast model bridge decks and the other two from laboratory-cast specimens. Mix designs were selected based on their extent of use around the state, with differences in terms of type of cement, coarse aggregate type, and supplementary cementitious materials. Wet-mat curing durations of 0, 2, 4, 8, 10 and 14 days were evaluated for each mix. Experimental results showed that no significant benefit for resistance to chloride permeability beyond 2, 4 or 8 days depending on the mixture, beyond which the benefits appeared to diminish. A comparison of results obtained from the RCPT and its alternative test; the ponding test, showed a correlation between their results for some mixtures.
