From the gradation curve and size distribution, fineness modulus
(FM) of IFS aggregate was found to be 7.19.
A blend of fine aggregate (70% Qibla Bandi and 30% of Chenab river sand) having fineness modulus
of 2.49 and Specific gravity of 2.68 was introduced in concrete mix design (Table1-B).
Copper slag in granular form with fineness modulus
of 3.22 and specific gravity of 3.63
As per ACI 211.4R-93 , a mixture of concrete has been recommended to use the fine aggregate with fineness modulus
values from 2.4 to 3.2.

The researchers found that all residual foundry sands, when used in concrete and concrete blocks in amounts not exceeding the fineness modulus
limits of the fine aggregate addition, give acceptable compressive strengths.
