Replace fine aggregates or natural sand ? As if you replace fine aggregates from concrete it will become "No fines Concrete " used for specific purposes to prepare pervious media. If you want to replace natural sand on the other hand there are plenty of options available which are now even approved as per IS 383 2016
copper slag was 2.67 & 2.75 respectively as shown in Table 2.1. The water absorption of 20 mm coarse aggregates, sand &copper slag was found to be 0.609, 1.01 and 0.65 respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is affected due to it.

of aggregates. These are obtained from natural rocks and river beds, thus degrading them slowly. This issue of environmental degradation, and need for aggregates demands for the usage of any other alternative source. Thus the concept of replacement of coarse aggregate with steel slag and fine aggregate with ecosand seems to be promising.
materials which can fully or partially replace the natural aggregate without affecting the property of concrete. The different materials that can be used as an alternative for natural fine aggregate include blast furnace slag, manufactured sand, crushed glass, copper slag, recycled aggregates, fly ash aggregate, steel slag etc. The use of
