Table 5 Mix proportion for wet packing density test with recycled sand

1. W-RS-n, W wet packing, RS recycled sand, n batch number; 2. binder:sand = 45%:55% by vol.; 3. FA replaces OPC by 10% by vol.; 4. (SF + QP) replaces binder by 20% by vol.; 5. SF:QP = 20%:0%, 15%:5%, 10%:10%, 5%:15%; 6. W/B = 0.20; 7. SP and DF amount is 4.0% and 0.1% of total binder amount, respectively, in all mixes
