Extracted text: Q1- A concrete mix of (1: 2.5: 3.3/0.57) (by weight), is used for casting in Hot weather. Calculate: 1. The temperature of the mix with no ice (in Fahrenheit and Celsius). 2. The weight of ice that may be required to produce the maximum allowed temperature in hot weather (80 °F). Assume: S.G. of aggregate = 2.65. Te = Tsand = 120 °F, Tgravel = 125 °F, Tm = 110 °F.
