: 6) At a ready-mix concrete plant 65 tons of cement, 190 tons of fine aggregate, 250 tons of coarse aggregate and 50 tons of water are available before the end of the day. The plant manager knows that the next day (s)he has to deliver a total of 200 m³ of concrete. In the laboratory, the moisture content of sand and gravel was determined as 1.2 % and 0.2%, respectively and the absorption capacities are 0.8 % for both materials. SSD bulk specific gravities are 2.60 and 2.70 for sand and gravel, respectively. Specific gravity of cement is 3.15.
