Sample RBSE Sec Voc Construction Practice Questions

Try these sample questions to test your RBSE Sec Voc Construction exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Ordinary Portland Cement (OPC) hardens and gains strength mainly because of:
A.Evaporation of water only, without any chemical reaction
B.A chemical reaction with water called hydration
C.Mixing with oil that seals pores instantly
D.Heating the bag in sunlight for one hour
Explanation: Cement sets and gains strength by hydration—a chemical reaction between cement compounds and water that forms binding hydrates.
2Which material is commonly used as fine aggregate in ordinary concrete for buildings?
A.River sand or crushed sand of suitable grading
B.Large boulders larger than 150 mm only
C.Fresh cow dung mixed with straw
D.Scrap plastic bags only
Explanation: Fine aggregate is sand (natural river sand or manufactured crushed sand) that fills voids between coarse aggregate and improves workability.
3Coarse aggregate in concrete is generally material that:
A.Passes completely through a 75 µm sieve
B.Is retained on a 4.75 mm sieve (as commonly defined for concrete)
C.Is only liquid admixture
D.Is pure cement powder
Explanation: In standard concrete practice, coarse aggregate is typically retained on the 4.75 mm sieve, while fine aggregate largely passes that sieve.
4First-class burnt clay bricks used for load-bearing walls should ideally be:
A.Soft, under-burnt, and easily scratched with a fingernail
B.Well burnt, uniform in size and colour, with sharp edges and a ringing sound when struck
C.Warped and cracked so water can escape
D.Made only of pure sand without clay
Explanation: Good quality bricks are well burnt, uniform, sharp-edged, and give a clear metallic ring when struck together—signs of adequate burning and density.
5Efflorescence on brickwork usually appears as a white powdery deposit caused mainly by:
A.Soluble salts brought to the surface by moisture and left after evaporation
B.Too much polishing with wax only
C.Using only distilled water in curing
D.Painting with dark colours only
Explanation: Efflorescence is a white salt deposit formed when soluble salts in bricks/mortar dissolve in moisture, migrate to the surface, and crystallize as water evaporates.
6Mild steel reinforcement bars used in RCC primarily provide:
A.Only colour to the concrete surface
B.Tensile strength, which plain concrete lacks
C.Complete waterproofing without any cover
D.Heat insulation equal to foam
Explanation: Concrete is strong in compression but weak in tension. Steel reinforcement supplies tensile (and shear/ductility) capacity in reinforced cement concrete (RCC).
7The water–cement ratio in concrete mainly influences:
A.Only the colour of formwork timber
B.Strength and durability of the hardened concrete
C.The brand name printed on the cement bag
D.The height of scaffolding towers only
Explanation: A lower water–cement ratio (within workable limits) generally increases strength and durability; excess water weakens the paste and increases porosity.
8Which statement about curing of concrete is correct?
A.Curing keeps concrete moist so hydration can continue and strength can develop
B.Curing means painting dry concrete immediately with oil paint
C.Curing requires freezing the slab overnight in all climates
D.Curing is only needed for steel bars, not concrete
Explanation: Curing maintains adequate moisture and temperature so cement hydration continues, improving strength and reducing early drying cracks.
9Fly ash, when used as a partial cementitious material in concrete, can help to:
A.Increase early heat of hydration sharply in every case without other effects
B.Improve long-term properties and reduce cement content when properly designed
C.Replace all coarse aggregate completely
D.Eliminate the need for any water in the mix
Explanation: Properly designed fly ash blends can improve workability and long-term strength/durability and reduce Portland cement demand; it is not a full aggregate replacement.
10The standard consistency of cement paste is determined mainly using which apparatus concept?
A.Vicat apparatus with a plunger under specified load/time conditions
B.A simple kitchen spoon without any standard procedure
C.Only a tape measure on a brick wall
D.A spirit level on scaffolding
Explanation: Standard consistency of cement is found with the Vicat apparatus by measuring plunger penetration into cement paste under standard conditions.
