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.Assuming that the aggregate has negligible absorption, calculate th
How would you know a strong acid from a weak acid without looking at some data? For example HBr, HI, HCI are all stong acids but HF or HB is a weak acid. I am asking because when you mix in a solution the strong acid determines the PH. Hope you ca
