List the types of aggregate used in concrete and their desirable characteristics.
You see the concrete looks dry as it is being placed as a slab. a) If you decide to spray some water on the surface before the concrete has set, what could happen to the concrete in terms of strength and any potential abnormalities/distresses? b) You decide to instead wait for the concrete to set, and then you decide spray water on the surface. What could happen to the concrete in terms of strength, shrinkage, density, and any potential distresses?

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:
