The volume method calculates the amount of fine aggregate based on 1 yd3 (1m3) of concrete while the weight method performs the calculation based on an estimation of concrete weight. Depending on the type of concrete (non-air-entrained or air-entrained), the first estimate of concrete weight can be calculated using ACI Table 6.3.7.1/ A1.5.3.7.1
