Design Environment The designed concrete will be used for plain footings. Concrete exposed to freezing and thawing in a moist condition 10000 ppm 22 MPa 25.08 Mpa Sulfate (SOA) in water Required design strength, fc Target design strength for Minimum dimension Minimum space between rebars 0.5 m 50 mm Minimum cover over rebars 50 mm Nominal Maximum Size of 37.5 mm Coarse Aggregates The mix design will not include air-entrainer or another admixture. For the given information above; A) Find the water-cement ratio (w/c) using corresponding tables and check whether the w/c meets the maximum w/c requirements and decide the final w/c [10 Points) B) Decide the proper slump range [5 Points) C) Check whether the coarse aggregate requirements meet (10 Points) D) Check whether the minimum design compressive strength requirements meet (10 Points] E) Explain the weight proportioning and the absolute volume methods and discuss the difference between them using your own words (15 Points)
