A mine X needs to produce an embankment (with concrete) for an amount of 12 417 tons/day of rejected filtrated tailings at a percentage of a solid mass of Cw= 87%. The volumic mass of the tailings grains is at ps= 3170 kg/m^3 (Gs = 3.17) The binder used is the Portland concrete, used for general uses (Type GU), with a relative value of Gs= 3.15 and a proportion of 5%. Knowing that the subsidence goal is 7' (178mm), which is linked to a percentage of a solid mass of the embarkment equal to Cw= 78%, calculate: 1) The total volumic mass (p) and the total volumic weight (y) 2) The dry volumic mass (PD) and the dry volumic weight (yd)
