सही: ० / ०
-
The aggregate impact value test is used to assess an aggregate's:
सही उत्तर: ग) Toughness, i.e. resistance to sudden shock
The impact value test measures resistance to fracture under repeated hammer blows, indicating toughness; abrasion is assessed by the Los Angeles test.

-
The fineness of cement expressed as its specific surface (m²/kg) is determined by the:
सही उत्तर: ग) Blaine air permeability method
The Blaine air permeability apparatus measures specific surface, an indicator of fineness; sieving is the cruder alternative.

-
The specific gravity of ordinary Portland cement is approximately:
सही उत्तर: घ) 3.15
OPC has a specific gravity of about 3.15; 2.65 is typical for aggregates, 1.44 t/m³ is the bulk density of cement and 7.85 is for steel.

-
The number 43 in the designation '43 grade ordinary Portland cement' refers to its:
सही उत्तर: क) Minimum 28-day compressive strength of 43 N/mm²
Grades 33, 43 and 53 of OPC indicate the minimum 28-day compressive strength in N/mm² of standard mortar cubes.

-
Lateral-torsional buckling must be checked mainly for:
सही उत्तर: ख) Laterally unsupported beams bent about their major axis
A beam bent about its major axis without adequate lateral restraint can buckle by twisting and deflecting sideways; full lateral restraint prevents it.

-
A failure at the end connection of a steel tension member in which a block of the member tears out along a shear plane and a perpendicular tension plane is called:
सही उत्तर: ख) Block shear failure
Block shear is a rupture mode in which a block of material separates by shear along one path and tension along another at bolted or welded ends.

-
In built-up steel columns, lacing and battening are provided mainly to:
सही उत्तर: ग) Connect the separate components so that they act together as a single column
Lacing bars or batten plates tie the component sections together so the built-up member behaves as one unit and resists buckling.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
High strength friction grip (HSFG) bolts in a slip-critical joint transfer load between connected plates mainly by:
सही उत्तर: घ) Friction between the clamped plate surfaces
HSFG bolts are tightened to a high pretension, clamping the plates so that load is transferred by friction at the faying surfaces.

-
As per IS 456:2000, the nominal cover to longitudinal bars in a column should not be less than 40 mm nor less than:
सही उत्तर: क) The diameter of the bar
IS 456 clause 26.4.2.1 requires a nominal cover of at least 40 mm, and not less than the bar diameter, for longitudinal column bars.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
For spans up to 10 m, IS 456 gives the basic span-to-effective-depth ratio for a cantilever beam as:
सही उत्तर: क) 7
The basic l/d ratios are 7 for cantilevers, 20 for simply supported and 26 for continuous members.
