Civil Engineering flashcards for UPSC ESE Civil Engineering
24 of 56 cards from the Civil Engineering deck — real questions with worked answers.
What are the three categories of properties of building materials, with one example of each?
Physical properties (e.g. density, porosity, water absorption), Mechanical properties (e.g. strength, hardness, elasticity), and Chemical/thermal properties (e.g. corrosion resistance, thermal conductivity).
Define bulk density and specific gravity of a building material.
Bulk density is mass per unit volume including pores: $\rho_b=\frac{m}{V}$. Specific gravity is the ratio of the density of the material to the density of water: $G=\frac{\rho_{material}}{\rho_{water}}$ (dimensionless).
How are porosity and void ratio related to durability of a building material?
Porosity $n=\frac{V_v}{V}$ is the ratio of voids to total volume; void ratio $e=\frac{V_v}{V_s}$ relates voids to solids. Higher porosity increases water absorption and freeze-thaw damage, reducing durability and strength.
What is the difference between water absorption and permeability of a material?
Water absorption is the quantity of water a material soaks up (mass gain, expressed as % of dry mass) under no pressure. Permeability is the ability of the material to allow water to pass through under a pressure gradient.
Classify building materials based on origin/processing.
Natural materials (stone, timber, sand, clay) used with minimal processing, and Artificial/manufactured materials (brick, cement, glass, steel, concrete) produced by processing raw materials.
State the standard sizes of a modular brick (nominal and actual) used in India.
Nominal (modular) size is $200\times100\times100\,\text{mm}$ including a 10 mm mortar joint; actual brick size is $190\times90\times90\,\text{mm}$.
What is the Bogue compound C3S, and what property of cement does it govern?
$\ce{C3S}$ (tricalcium silicate, $\ce{3CaO.SiO2}$) governs early strength and rate of hardening; it hydrates fast and is responsible for strength up to 28 days.
List the main types of cement and one use for each (any three).
Ordinary Portland Cement (OPC) — general construction; Portland Pozzolana Cement (PPC) — mass/marine works; Rapid Hardening Cement — early formwork removal; Sulphate Resisting Cement — sulphate-rich soils.
What is seasoning of timber and why is it done?
Seasoning is the controlled drying of timber to reduce its moisture content to a safe level. It is done to reduce shrinkage, warping, decay, and to improve strength, dimensional stability and workability.
Name the standard laboratory tests for the compressive strength of cement and of bricks.
Cement compressive strength is tested on $70.6\,\text{mm}$ cement-sand mortar cubes (1:3). Brick compressive strength is tested by crushing the brick in a compression testing machine; minimum for common burnt clay brick is about $3.5\,\text{N/mm}^2$.
What do the initial and final setting time tests of cement using the Vicat apparatus measure?
Initial setting time = time from adding water until the paste begins to lose plasticity (Vicat needle penetrates to $5\pm0.5$ mm from base); for OPC it must be $\geq30$ min. Final setting time = time until the paste fully hardens (annular attachment leaves no impression); $\leq600$ min.
What is the slump test and what does it indicate?
The slump test measures the workability (consistency) of fresh concrete by recording the subsidence (slump) of a concrete cone when the mould is removed. Higher slump indicates higher workability/water content.
Define stress and strain, and give the formula for each.
Stress is internal force per unit area: $\sigma=\frac{P}{A}$. Strain is the deformation per unit original length: $\varepsilon=\frac{\Delta L}{L}$ (dimensionless).
State Hooke's law and define Young's modulus.
Within the elastic limit, stress is proportional to strain: $\sigma=E\varepsilon$. Young's modulus $E=\frac{\sigma}{\varepsilon}$ is the constant of proportionality (modulus of elasticity).
Define Poisson's ratio and give its typical range for metals.
Poisson's ratio is the ratio of lateral strain to longitudinal strain: $\nu=-\frac{\varepsilon_{lateral}}{\varepsilon_{longitudinal}}$. For most metals $\nu\approx0.25$ to $0.33$; theoretical limits are $0$ to $0.5$.
Write the relationships among elastic constants $E$, $G$, $K$ and $\nu$.
$E=2G(1+\nu)$, $E=3K(1-2\nu)$, and combined: $E=\frac{9KG}{3K+G}$, where $G$ is shear modulus and $K$ is bulk modulus.
What is the formula for strain energy stored in an axially loaded bar?
$U=\frac{P^{2}L}{2AE}=\frac{\sigma^{2}}{2E}\times V$, where $V=AL$ is the volume of the bar.
State the relationships between load $w$, shear force $V$, and bending moment $M$ along a beam.
$\frac{dV}{dx}=-w$ and $\frac{dM}{dx}=V$. Thus bending moment is maximum where shear force is zero (or changes sign).
For a simply supported beam of span $L$ with a central point load $W$, give the maximum bending moment and maximum shear force.
Maximum bending moment $M_{max}=\frac{WL}{4}$ at midspan; maximum shear force $V_{max}=\frac{W}{2}$ at the supports.
For a simply supported beam of span $L$ carrying a UDL of intensity $w$, give the maximum bending moment and shear force.
Maximum bending moment $M_{max}=\frac{wL^{2}}{8}$ at midspan; maximum shear force $V_{max}=\frac{wL}{2}$ at each support.
State the flexure (bending) formula and name each term.
$\frac{M}{I}=\frac{\sigma}{y}=\frac{E}{R}$, where $M$ = bending moment, $I$ = second moment of area, $\sigma$ = bending stress at distance $y$ from neutral axis, $E$ = Young's modulus, $R$ = radius of curvature.
Define section modulus and give its expression for a rectangular section $b\times d$.
Section modulus $Z=\frac{I}{y_{max}}$; for a rectangle $Z=\frac{bd^{2}}{6}$. It relates moment capacity to allowable stress: $M=\sigma Z$.
Write the transverse shear stress distribution formula in a beam.
$\tau=\frac{VQ}{Ib}$, where $V$ = shear force, $Q=A\bar{y}$ = first moment of area above the level considered, $I$ = second moment of area, $b$ = width at that level. For a rectangle $\tau_{max}=\frac{3}{2}\frac{V}{A}$.
State the torsion equation for a circular shaft and name each term.
$\frac{T}{J}=\frac{\tau}{r}=\frac{G\theta}{L}$, where $T$ = torque, $J$ = polar moment of inertia, $\tau$ = shear stress at radius $r$, $G$ = shear modulus, $\theta$ = angle of twist over length $L$.
Planning Civil Engineering for UPSC ESE Civil Engineering
Civil Engineering is about 77% of the UPSC ESE Civil Engineering syllabus by topic count — 43 of 56 topics, spread over 11 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 30 hours.
The heaviest chapters are Solid Mechanics (4 topics), Structural Analysis (4 topics), Design of Steel Structures (4 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
