Q/ A 1: 1.8: 4.5 mix has a water/cement ratio of 0.6 and a cement content of 300 kg/m3. The temperature of the ingredients are as follows: cement 180C, aggregate:300C, water:20 0C.a)Assuming that the aggregate has negligible absorption, calculate the temperature of the fresh concrete.b)How much ice is required to reduce the temperature of the fresh concrete to 16 0C?c)What is the weight of
