Sample Punjab PSEB Matric NSQF Construction Practice Questions

Try these sample questions to review concepts for the Punjab PSEB Matric NSQF Construction exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The modular (standard) actual size of a common clay brick used in Indian school masonry training is approximately:
A.19 cm × 9 cm × 9 cm
B.30 cm × 20 cm × 15 cm
C.10 cm × 10 cm × 10 cm only
D.50 cm × 25 cm × 12 cm
Explanation: In Indian modular brick practice taught in Assistant Mason pathways, the actual modular brick size is about 19 × 9 × 9 cm; with mortar joints the nominal size is taken as 20 × 10 × 10 cm.
2When a modular brick is laid with mortar joints, its nominal size is taken as:
A.15 cm × 7.5 cm × 7.5 cm
B.20 cm × 10 cm × 10 cm
C.25 cm × 12 cm × 8 cm
D.30 cm × 15 cm × 10 cm
Explanation: Nominal modular brick size includes one mortar joint allowance and is 20 × 10 × 10 cm, while the actual burnt clay unit is about 19 × 9 × 9 cm.
3The frog (depression) on a brick is provided mainly to:
A.Make the brick lighter only for transport, with no structural purpose
B.Store paint during finishing of walls
C.Form a key for mortar and often carry the maker’s mark, improving bond
D.Allow electrical conduits to pass through every brick
Explanation: The frog creates a mortar key that improves bond between courses and commonly carries the manufacturer’s stamp. When laying, the frog is kept upward so mortar fills it.
4First-class burnt clay bricks used for good masonry should generally be:
A.Soft, under-burnt, and able to be scratched easily with a fingernail
B.Well burnt, uniform in shape, free from large cracks, and give a clear ringing sound when struck
C.Covered with a thick glaze on all six faces only
D.Made entirely of pure lime without clay
Explanation: Good first-class bricks are well burnt, regular in size/shape, free from serious cracks or lumps, and produce a clear metallic ring when two bricks are struck together—signs of proper burning and density.
5Bricks should be soaked in clean water before laying mainly because:
A.Dry bricks look darker and hide mortar stains
B.Soaking removes the need for any mortar
C.Only decorative face bricks ever need moisture
D.Dry bricks suck water from mortar too quickly, weakening the bond
Explanation: Dry, porous bricks absorb water from fresh mortar rapidly, leaving a weak, poorly hydrated joint. Pre-soaking (then allowing surface water to drain) keeps mortar workable and improves bond.
6Which material is the usual hydraulic binder in ordinary cement mortar for brickwork?
A.Portland cement (ordinary Portland cement / OPC or as specified)
B.Pure table salt
C.Only vegetable oil
D.Plastic packing tape
Explanation: Ordinary cement mortar uses Portland cement (or the grade specified on site) as the binder with sand and water. Salt, oil, or tape are not masonry binders.
7Sand for good mortar should preferably be:
A.Clean, well graded, free from excessive clay, silt, organic matter, and salt
B.Full of clay lumps to make mortar sticky forever
C.Sea sand used without any washing or checking
D.Only very coarse gravel larger than 20 mm
Explanation: Masonry sand should be clean and well graded. Excess clay, silt, organics, or salts weaken mortar and cause staining or delayed hardening. Sea sand needs careful washing/approval if used at all.
8Water used for mixing mortar and curing masonry should be:
A.Oily industrial waste water only
B.Sea water for all interior plaster without exception
C.Reasonably clean and free from harmful salts, oils, acids, and organic impurities
D.Any coloured chemical drain water
Explanation: Mixing and curing water should be clean enough not to interfere with cement hydration—generally free from harmful salts, oils, acids, alkalis, and organic matter. Contaminated water weakens mortar and concrete.
9In stone masonry classification by finish and dressing, the two main groups are:
A.Rubble masonry and ashlar masonry
B.Only English bond and Flemish bond
C.Only PCC and RCC
D.Only tiling and plastering
Explanation: Stone masonry is commonly classed as rubble (irregular or roughly dressed stones) and ashlar (accurately dressed stones with fine joints). English/Flemish are brick bonds; PCC/RCC are concrete systems.
10A through stone in a stone wall is placed so that it:
A.Sits only as a decorative cornice above the plinth
B.Spans the full thickness of the wall, tying the faces together
C.Is laid only parallel to the face and shorter than wall thickness
D.Is used only in dry stacks without any structural role
Explanation: A through stone (header) runs through the wall thickness with its long dimension into the wall, bonding the two faces and resisting separation under load or settlement.

About the Punjab PSEB Matric NSQF Construction Exam

The Punjab PSEB Matric Construction (NSQF) examination is the Class 10 vocational skill subject Construction, subject code 90, job role Assistant Mason, conducted under the Punjab School Education Board. Per the official Scheme of Studies, candidates are assessed with Theory 40 marks, Practical 50 marks, and Internal Assessment (INA) 10 marks (grand total 100). Theory and practical cover Assistant Mason competencies such as masonry materials, hand tools, mortar preparation, brick/block bonding concepts, temporary scaffold assist and site safety, measurements, and reading basic building drawings—aligned with school NSQF Construction and the broader CON/Q0102 Assistant Mason pathway (CSDCI). Typical Matric NSQF theory duration on recent date sheets is about 3 hours 15 minutes (for example 11:00 AM to 2:15 PM). The 100 questions on this page are an English-language multiple-choice study adaptation for theory and viva readiness; they do not replace official practical assessment or claim to be an official PSEB paper.
