Extracted text: The volume of concrete required for a certain project is 20m^3. The density of concrete is 2400kg/ m^3. Concrete is composed of fine and coarse aggregates, water, and cementitious materials: cement and fly ash. The ratio of fine and coarse aggregates is 2:1. Water-to-cement ratio is 0.40. Percentage of the fly ash to the total cementitious material is 0.30. Total aggregate-to-cement ratio is 5:1. Density of fine aggregates is 2680kg/m^3. Density of coarse aggregate is 2500kg/m^3. Density of water is 1000kg/m^3. Density of cement is 3150kg/m^3. Density of fly ash is 1300kg/m^3. Determine the weight required for each component. All ratios use weights. Round off your answers to the nearest tenth of a kilogram. Have one significant figure after the decimal point. Find: Weight of Fine Aggregates: Weight of Coarse Aggregates: Weight of Water: Weight of Cement: Weight of Fly Ash:
