As an engineer in charge for concrete mixing, you are requested to prepare concrete mixes for a housing construction project. Therefore, a few things need to be considered prior to the mixing process. (a) If the cube test recorded lower compressive strength than the required minimum strength stated in the drawing, suggest an immediate action need to be taken by the engineer? (b) Describe the steps to design a concrete mixture using DOE method for normal concrete. (c) Explain FIVE (5) factors that are required for determining mix design proportion.

You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1963 lb/yd3of dry gravel, 4% aircontent, and 565 lb/yd3of cement. The available gravel has a specific gravity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. Theavailable sand has a specific gravity of Gsand = 2.5, a moisture content of4.8%, and absorption of 1.5%. For each cubic yard of concrete needed onthe job, calculate the weights of cement, moist gravel, moist sand, and waterthat should be added to the batch. Summarize and total the mix design whenfinished (don’t include air entrainer in summary)
