The correct option is B 0.85 P % of weight of cement
The time elapsed between the moment that the water is added to the cement, to the time that the paste starts losing its plasticity. 300 gm of cement is taken and made a cement paste of consistency 0.85 P. When the needle penetrates only to a depth of 33 to 35 mm from the top (5 to 7mm from bottom), the test is completed
