You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1165 kg/m3 of dry gravel, 4% air content, and 335 kg/m3 of cement. The available gravel has a specific gravity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. The available sand has a specific gravity of Gsand = 2.5, a moisture content of 4.8%, and absorption of 1.5%. For each cubic meter of concrete needed on the job, calculate the mass of cement, moist gravel, moist sand, and water that should be added to the batch. Summarize and total the mix design when finished (don’t include air entrainer in summary).
