-
In Flemish bond brickwork, each course consists of:
सही उत्तर: ग) Alternate headers and stretchers in the same course
Flemish bond places headers and stretchers alternately in every course, giving a more attractive face than English bond.

The actual dimensions of a standard modular brick as per Indian Standards are:
सही उत्तर: घ) 190 × 90 × 90 mm
The modular brick measures 190 × 90 × 90 mm; with a 10 mm mortar joint its nominal size becomes 200 × 100 × 100 mm.

Superplasticisers (high-range water reducers) in concrete allow:
सही उत्तर: क) A large reduction in water content for the same workability
Superplasticisers disperse cement particles strongly, permitting water reductions of the order of 20-30% or flowing concrete at the same w/c ratio.

-
Air-entraining admixtures are added to concrete mainly to improve its:
सही उत्तर: ख) Resistance to freezing and thawing
Tiny entrained air bubbles relieve pressure from freezing water, improving freeze-thaw durability (and workability), though strength reduces slightly.

-
The ultrasonic pulse velocity (UPV) test on concrete is mainly used to assess its:
सही उत्तर: ख) Uniformity and quality, and to detect internal cracks or voids
Pulse velocity through concrete depends on its density and continuity, so UPV indicates quality, homogeneity and internal defects.

-
The rebound (Schmidt) hammer test on hardened concrete measures the:
सही उत्तर: ग) Surface hardness, which is correlated with compressive strength
The rebound number reflects surface hardness and is used through calibration curves to estimate compressive strength non-destructively.

-
A doubly reinforced beam is generally provided when:
सही उत्तर: क) The depth of the beam is restricted and a singly reinforced section cannot resist the moment
When depth is limited, compression steel is added so the section can resist moments beyond the limiting moment of a balanced singly reinforced section.

-
In concrete mix design, the target mean strength is obtained from the characteristic strength fck and standard deviation s as:
सही उत्तर: घ) fck + 1.65s
Target mean strength = fck + 1.65s, so that not more than 5% of results fall below fck.

As per IS 456:2000, the horizontal spacing of main reinforcement bars in a solid slab shall not exceed:
सही उत्तर: घ) 3d or 300 mm, whichever is less
Main bars in slabs are limited to the lesser of three times the effective depth and 300 mm (distribution bars: 5d or 450 mm).
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
As per IS 456:2000, the minimum reinforcement in each direction of a slab using high-strength deformed (HYSD) bars is:
सही उत्तर: ख) 0.12% of the gross cross-sectional area
Slabs need at least 0.12% of gross area with HYSD bars and 0.15% with mild steel bars.
