You are working on a concrete mix design that requires eachcubic yard of concrete to have 0.45 water–cement ratio, 1963lb/yd³ of dry gravel, 4% air content, and 565lb/yd³ of cement. The available gravel has aspecific gravity of G_gravel = 2.7, amoisture content of 1.6%, and absorption of 2.4%. The availablesand has a specific gravityof G_sand = 2.5, a moisture content of4.8%, and absorption of 1.5%. For each cubic meter of concreteneeded on the job, calculate the mass of cement, moist gravel,moist sand, and water that should be added to the batch.
