Assertion (A): RCC structures resist both compression and tension effectively. Reason (R): Steel bars are provided in RCC to resist compressive stresses.
Assertion (A): Water-cement ratio influences strength of concrete. Reason (R): A lower w/c ratio increases the workability of concrete.
Assertion (A): Bitumen is used in road construction for binding aggregates. Reason (R): Bitumen increases the permeability of the pavement layer.
Assertion (A): Theodolite is used to measure horizontal and vertical angles. Reason (R): It cannot be used to prolong a straight line.
Calculate the area of a triangle with base 6 m and height 4 m.
A concrete beam 230 mm × 450 mm is subjected to a shear force of 90 kN. Find average shear stress.
What is the unit weight of RCC with density 2500 kg/m³ under gravity 9.81 m/s²?
If a pipe of diameter 100 mm carries water at 2 m/s, what is discharge?
Assertion (A): Soundness test is performed on cement to check its ability to resist volume change. Reason (R): Soundness ensures long-term durability.
Assertion (A): A pile foundation is used where soil bearing capacity is low. Reason (R): Piles transfer load to weak soil strata.
Calculate the volume of a cylinder with diameter 1.2 m and height 2 m.
How many bricks are required for a 1.5 m³ brickwork if 500 bricks are needed per m³?
Determine the length of a curve of radius 100 m subtending an angle of 60°.
Assertion (A): Proper curing improves the strength of concrete. Reason (R): Curing increases the rate of hydration.
Assertion (A): Contour lines close together indicate steep slopes. Reason (R): They show equal horizontal distances.
Assertion (A): Sewage should not be discharged into drinking water sources. Reason (R): It contains pathogens that are beneficial to health.
Assertion (A): Road rollers are used for compacting subgrade. Reason (R): Compaction reduces void ratio and increases strength.
Calculate the rise of a 3 m long slab having a slope of 1 in 20.
If a circular column has a diameter of 500 mm, what is its cross-sectional area?
Determine the weight of 1.5 m³ of PCC with density 2400 kg/m³.

Assertion (A): A cantilever beam has zero moment at the free end. Reason (R): Maximum bending moment occurs at the fixed support.
Assertion (A): Rapid sand filters require less area than slow sand filters. Reason (R): This is due to higher filtration rates.
Assertion (A): Proper alignment of tunnels reduces construction cost. Reason (R): Misalignment causes less ventilation inside tunnels.
Calculate the volume of a trapezoidal footing with top area 4 m², bottom area 6 m², and depth 0.5 m.
If a water tank has a diameter of 3 m and height of 5 m, what is the storage capacity?
Calculate total cost of 1.2 m³ of concrete at ₹6500 per m³.

Assertion (A): Well-graded aggregates improve the workability of concrete. Reason (R): They contain particles of nearly the same size.
Assertion (A): Soil bearing capacity depends on type, depth, and water content. Reason (R): Loose saturated sands have low bearing capacity.
Assertion (A): Bridge abutments support the deck at the ends. Reason (R): They help transfer vehicular loads directly to the piers.
Calculate the pressure exerted by a 3 m water column. (γ = 9.81 kN/m³)

Assertion (A): Bitumen is used in road construction for flexible pavement. Reason (R): It provides rigidity to the structure.
Assertion (A): Aeration in water treatment helps remove dissolved gases. Reason (R): It increases CO₂ content in water.
Assertion (A): A tie beam is used to connect column footings. Reason (R): It resists lateral soil pressure.
Assertion (A): A septic tank allows anaerobic decomposition. Reason (R): It is part of a primary treatment system.
