Question 3
Calculate the specific gravity of cement when tested in le-chattier flask if 15cc of kerosene is poured into it and after the addition of cement & removal of air, the level of kerosene is 40cc. Assume density of kerosene = 0.81 g/cc
Question 4
Which of the following statements are incorrect in respect to the air-entrained Portland cement?

2. Entrained air bubbles also help in reducing the unit weight of construction and increasing the workability & durability. Less unit weight accounts for less weight of cement.
