Initial Setting Time Test on Cement
The initial setting time test is conducted on cement to determine the time at which the cement paste loses its plasticity and becomes hard. This is an important test as it helps in determining the time within which the cement should be used after mixing with water.
Amount of Water Used in Conducting the Test
The amount of water used in conducting the initial setting time test on cement is expressed as a percentage of the standard consistency of cement. The standard consistency of cement is the consistency at which the Vicat plunger penetrates to a depth of 5-7 mm from the bottom of the Vicat mould.
Answer
The correct answer to the question is option 'B', which states that the amount of water used in conducting the initial setting time test on cement is 0.85p, where p is the standard consistency of cement.
Explanation
The initial setting time test is conducted using a Vicat apparatus. A cement paste is prepared by adding a certain amount of water to the cement. The paste is then placed in the Vicat mould and the plunger is brought down gently so that it just touches the surface of the paste. The plunger is then released and the time is noted when the paste loses its plasticity and the plunger penetrates to a depth of 5-7 mm.
The amount of water used in conducting the test is 0.85 times the standard consistency of cement. This means that if the standard consistency of cement is p, then the amount of water used in the test would be 0.85p. This is because the cement paste used in the test should have a consistency that is 85% of the standard consistency.
Conclusion
In conclusion, the amount of water used in conducting the initial setting time test on cement is 0.85 times the standard consistency of cement. This is an important test as it helps in determining the time within which the cement should be used after mixing with water.

Normal consistency is the percentage of water that is added tothe cement to form a paste of a certain thickness. /
सामान्य सुसंजनता पानी का वह प्रतिशतहै जिसको सीमेन्ट में मिलाने से एक निश्चित गाढेपन का पेस्ट बनता है।
0.85
P times the amount of water required to make a paste ofnormal consistency is taken.
For this reason, normal consistency is tested before theinitial setting time test of the cement.
सामान्य सुसंजनता का पेस्ट बनाने के लिये जितनेपानी की आवश्यकता होती है उसका
0.85P
गुनापानी लिया जाता है। इसी कारण सीमेन्ट केप्रारम्भिक जमाव समय परीक्षण से पहले सामान्य सुसंजनता का परीक्षण किया जाता है।
