However, there is limited literature available on the use of fine to coarse aggregate ratios for a mixed design for FRC. The maximal fine to coarse aggregate ratio described in ACI 544.3R-2008 is 0.6. Coarse and fine aggregate comprises almost up to 75% of total concrete volume, therefore, balancing the usage of FA and CA plays vital role in

Aggregate is typically divided into two components:! Fine aggregate including sand – material passing a 3/8-inch screen sieve, essentially all passing a # 4 sieve (i.e., a 0.187-inch square opening). ! Coarse aggregate including gravel – generally considered being crushed stone or gravel, almost all of which is retained on a No. 4 sieve.
