Near-Surface and Chloride Permeability of Concrete Using

The overuse level of cement and natural sand for civil industry has several undesirable social and ecological consequences. As an answer for this, industrial wastes called by-products (pozzolanic materials) like fly ash, GGBFS, silica fume and metakaolin can be used to interchange partially cement and natural fine aggregate by manufacturing sand (M-sand). Thus, the present research work
