(
1:3) Mix
1 YC of Cement : 21.6 Bags @ 10.50 = 226.80
3 YC of sand : 3 YC @ 15.00 = 45.00
4YC of cement & sand = 271.80
ADD 33% shrinkage = 89.70
--------
=> 4 YC of (1:3) mix = 361.50
so, Cost/YC = 90.38
=> Material cost/FS for 1" thick = 0.28
or cost/m2 (25mm thick) = 3.00
如果是(1:4) mix, 3YC of sand --> 4 YC of sand
4 YC of cement & sand ---> 5 YC of Cement & sand,建议用Excel 计算, 4 的 value = 1+3(用address value)3YC of sand --> 4 YC of sand,当时, 4 自动变为 5,其他的 value 也会自动重算!
