(4) Given the information below: • The mixing water content for the required concrete mix is 180 kg/m³; • A water to cement ratio used is 0.5; • Coarse aggregate has a dry-rodded bulk density of 1800 kg/m³, the dry bulk volume of rodded coarse aggregate per unit volume of concrete is 0.69, and the absorption of 0.5%. According to the ACI (American Concrete Institute) procedure for the concrete mix design, determine: (a) How much of cement (kg) is used for a cubic metre of this concrete? (b) How much of dry coarse aggregate (kg) is used for a cubic metre of this concrete? (c) How much of coarse aggregate (kg) on the basis of SSD (saturated surface dry) condition?
