Civil Engineering Drawing Multiple Choice Questions on “Earthwork, Concrete and R.C.C. work”.

1. _______________ are engineering works created through the processing of parts of the earth’s surface involving quantities of soil or unformed rock.
a) Surfacework
b) Landwork
c) Earthworks
d) Hosework
Answer: c
Clarification: Typical earthworks include roads, railway beds, causeways, dams, levees, canals, and berms. Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.

2. An ___________________ beam is one in which the tension capacity of the tensile reinforcement is smaller than the combined compression capacity of the concrete and the compression steel (under-reinforced at tensile face).
a) extra-reinforced
b) less-reinforced
c) under-reinforced
d) over-reinforced
Answer: c
Clarification: When the reinforced concrete element is subject to increasing bending moment, the tension steel yields while the concrete does not reach its ultimate failure condition. As the tension steel yields and stretches, an “under-reinforced” concrete also yields in a ductile manner, exhibiting a large deformation and warning before its ultimate failure. In this case the yield stress of the steel governs the design.

3. When aggregate is mixed together with dry Portland cement and water, the mixture forms a fluid _________ that is easily poured and moulded into shape.
a) curry
b) furry
c) slurry
d) gel
Answer: c
Clarification: A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with a liquid (usually water), often used as a convenient way of handling solids in bulk. Slurries behave in some ways like thick fluids, flowing under gravity and are also capable of being pumped if not too thick.

4. Excavation may be classified by type of material- Earth excavation ________ excavation, rock excavation, muck excavation, unclassified excavation.
a) bottom soil
b) sub-soil
c) topsoil
d) surface soil
Answer: c
Clarification: Topsoil is the upper, outermost layer of soil, usually the top 2 inches (5.1 cm) to 8 inches (20 cm). It has the highest concentration of organic matter and microorganisms and is where most of the Earth’s biological soil activity occurs. Four elements constitute the composition of soil. Those elements are mineral particles, organic matter, water, and air. The volume of top soil consists of 50 to 80% of these particles which form the skeletal structure of most soils.

5. Heavy construction equipment is usually used due to the amounts of material to be moved – up to millions of cubic metres.
a) True
b) False
Answer: a
Clarification: Earthwork construction was revolutionized by the development of the (Fresno) scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.

6. In the past, earthwork excavating calculations were done by hand using a slide rule and with methods such as Simpson’s rule.
a) True
b) False
Answer: a
Clarification: In numerical analysis, Simpson’s rule is a method for numerical integration, the numerical approximation of definite integrals. The slide rule, also known colloquially in the United States as a slipstick, is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for functions such as exponents, roots, logarithms and trigonometry, but typically not for addition or subtraction.

7. A mixture of bentonite and water used to make slurry walls.
a) True
b) False
Answer: a
Clarification: Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.

8. Manure slurry, a mixture of animal waste, organic matter, and sometimes water often known simply as “slurry” in agricultural use, used as fertilizer after ageing in a slurry pit.
a) True
b) False
Answer: a
Clarification: A slurry pit, also known as a farm slurry pit, slurry tank, slurry lagoon or slurry store, is a hole, dam, or circular concrete structure where farmers gather all their animal waste together with other unusable organic matter, such as hay and water run off from washing down dairies, stables, and barns, in order to convert it, over a lengthy period of time, into fertilizer that can eventually be reused on their lands to fertilize crops.

9. Chemical admixture may accelerate or slow down the rate at which the concrete hardens.
a) True
b) False
Answer: a
Clarification: Chemical admixtures are added to achieve varied properties. These ingredients may accelerate or slow down the rate at which the concrete hardens, and impart many other useful properties including increased tensile strength, entrainment of air and water resistance.

10. Concrete can be formulated with high tensile strength, but always has lower compressive strength.
a) True
b) False
Answer: b
Clarification: Reinforcement is often included in concrete. Concrete can be formulated with high compressive strength, but always has lower tensile strength. For this reason it is usually reinforced with materials that are strong in tension, typically steel rebar.

11. Reinforced concrete (RC) is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
a) True
b) False
Answer: a
Clarification: The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not.

12. Reinforced concrete can be classified as precast or postcast concrete.
a) True
b) False
Answer: b
Clarification: Reinforced concrete can be classified as precast or cast-in-place concrete. Designing and implementing the most efficient floor system is key to creating optimal building structures. Small changes in the design of a floor system can have significant impact on material costs, construction schedule, ultimate strength, operating costs, occupancy levels and end use of a building.

13. The coefficient of thermal expansion of concrete is very small to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.
a) True
b) False
Answer: b
Clarification: The coefficient of thermal expansion of concrete is similar to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.

14. The reinforcement in an RC structure, such as a steel bar, has to undergo the same strain or deformation as the surrounding concrete in order to prevent discontinuity, slip or separation of the two materials under load.
a) True
b) False
Answer: a
Clarification: Maintaining composite action requires transfer of load between the concrete and steel. The direct stress is transferred from the concrete to the bar interface so as to change the tensile stress in the reinforcing bar along its length, this load transfer is achieved by means of bond (anchorage) and is idealized as a continuous stress field that develops in the vicinity of the steel-concrete interface.

15. Prestressing concrete is a technique that decreases the load-bearing strength of concrete beams.
a) True
b) False
Answer: b
Clarification: Prestressing concrete is a technique that greatly increases the load-bearing strength of concrete beams.

a) d x d x s
b) (d2 x (ds)2)1/2
c) L.D (1 + s2)1/2
d) 2 L.D (1 + s2)1/2
Answer: c
Clarification: An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.

6. For 100 sq. m cement concrete (1 : 2: 4) 4 cm thick floor, the quantity of cement required, is ________
a) 0.90 m³
b) 0.94 m³
c) 0.98 m³
d) 0.98 m³
Answer: b
Clarification: Volume – area * thickness.
So, 100*.04 = 4 cubic metre, 10% for uneven surface.
4 * 10% = .04 = 4.4cubic metre.
50% for dry mortar, 4.4 * 50% = 2.2.
= 6.6cubic meter.

a) 0.90 m³
b) 0.94 m³
c) 0.98 m³
d) 0.98 m³

Answer: b
Clarification: Volume – area * thickness.
So, 100 *.04 = 4 cubic metre, 10% for uneven surface.
4 * 10% = .04 = 4.4cubic metre.
50% for dry mortar, 4.4 * 50% = 2.2.
= 6.6cubic meter.
Cement = 6.6/(1 + 2 + 4) = .94 cubic meter.

2. For the construction of buildings, the subheads of the estimate are ________
a) Earthwork, Concrete work, Brick work
b) Plastering or pointing, finishing, water supply and sanitary work
c) Brickwork Flooring, Wood work, Steel work
d) Earthwork, concrete work, brick work, plastering, water supply and steel work

Answer: d
Clarification: This method is suitable for walls of similar cross sections. Here the total centre line length is multiplied by breadth and depth of respective item to get the total quantity at a time. When cross walls or partitions or verandah walls join with main wall, the centre line length gets reduced by half of breadth for each junction. Such junction or joints are studied carefully while calculating total centre line length. The estimates prepared by this method are most accurate and quick.

3. The ‘centre line method’ is specially adopted for estimating?
a) Circular buildings
b) Hexagonal buildings
c) Other geometrical shaped buildings
d) Circular, hexagonal and other geometric shapes

Answer: d
Clarification: By center-line method, estimate for earthwork, concrete work or brick work for all walls of the building can be done at a time. If there are junctions, it needs to be carefully calculated deducting the widths. By long wall and short wall method, each wall is estimated separately. In centerline method, it can be prepared quickly eliminating lengthy mathematical calculations. In Center-line method, estimate can’t be physically measured at site where as it can be done for Long wall short wall method. Center-line method is preferred for preparing estimates and long wall short wall method is preferred for entering measurements in measurement book.

4. Referring to the figure below, pick up the correct statement from the following.

a) The total length of centre line of four walls is 20 m
b) Length of long wall out-to-out is 6.80 m
c) Length of short walls in-to-in is 3.20 m
d) Total length of four wall – 20 m, length of short wall – 6.8 m

Answer: d
Clarification: Total length is (long wall) 6.80. So, centre to centre length 6.80-80 = 6, 2 wall so 6+6 = 12.
Total length of short wall 4.80. So, centre to centre length 4.80-80 = 4, 2 wall so 4+4 = 8. Total length of center to centre 4 wall = 20 m.
Length of short wall in-to-in is 4.80-(80+80) = 3.20 m.

11. ____________ is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay.
a) Sapwood
b) Knot
c) Bark
d) Heartwood
Answer: d
Clarification: Heartwood formation is a genetically programmed process that occurs spontaneously. Some uncertainty exists as to whether the wood dies during heartwood formation, as it can still chemically react to decay organisms, but only once.
Heartwood is often visually distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker.

12. Stone walls are usually made of local materials varying from limestone and flint to granite and sandstone.
a) True
b) False
Answer: a
Clarification: However, the quality of building stone varies greatly, both in its endurance to weathering, resistance to water penetration and in its ability to be worked into regular shapes before construction. Worked stone is usually known as ashlar, and is often used for corners in stone buildings.

13. English garden wall bond course of headers bond has three courses of stretchers between every course of stretcher.
a) True
b) False
Answer: a
Clarification: For the standard English garden wall bond, headers are used as quoins for the middle stretching course in order to generate the lap, with queen closers as the penultimate brick at either end of the heading courses. A more complex set of quoins and queen closers is necessary to achieve the lap for a raking English garden wall bond.

14. Glued engineered wood products are manufactured by bonding together wood strands, veneers, lumber.
