सही: ० / ०
-
Gypsum is added to Portland cement clinker during grinding mainly to:
सही उत्तर: ग) Regulate (retard) the setting time
Gypsum controls the rapid reaction of C3A and prevents flash set.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which compound of Portland cement is mainly responsible for its early strength (first few weeks)?
सही उत्तर: घ) Tricalcium silicate (C3S)
C3S hydrates rapidly and gives early strength; C2S contributes to later strength.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which apparatus is used to test the soundness of cement?
सही उत्तर: ग) Le Chatelier apparatus
The Le Chatelier test measures expansion of cement due to free lime, i.e., soundness; Blaine apparatus measures fineness.

-
The Vicat apparatus is used in the laboratory to determine cement's:
सही उत्तर: ख) Normal consistency and setting times
Vicat apparatus with its plunger and needles measures standard consistency, initial and final setting time.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
For ordinary Portland cement, the initial setting time should not be less than:
सही उत्तर: क) 30 minutes
OPC must have an initial setting time of at least 30 minutes and a final setting time of not more than 600 minutes.

-
The slump test of fresh concrete is used to measure its:
सही उत्तर: ख) Workability (consistency)
The slump cone test is a field test that indicates the workability or consistency of fresh concrete.

-
For Fe 415 steel, the limiting value of the neutral axis depth ratio xu,max/d in limit state design to IS 456 is:
सही उत्तर: ख) 0.48
IS 456 gives xu,max/d = 0.53 for Fe 250, 0.48 for Fe 415 and 0.46 for Fe 500.

-
As per IS 456:2000, the flexural tensile strength (modulus of rupture) of concrete is taken as:
सही उत्तर: ख) 0.7√fck
IS 456 gives fcr = 0.7√fck N/mm².
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
As per IS 456:2000, the short-term static modulus of elasticity of concrete (in N/mm²) is estimated as:
सही उत्तर: ग) 5000√fck
IS 456 gives Ec = 5000√fck; 0.7√fck is the flexural strength.
