51.	‘Superplasticizers’ are chemicals which improve workability, which means the ability to shape the concrete before it has set.(a) True(b) FalseThis question was addressed to me in exam.The doubt is from Analysis of Rates of Cement Concrete in chapter Analysis of Rates of Civil Engineering Drawing
Answer» RIGHT CHOICE is (a) True The explanation: PIGMENTS can change the dull grey colour. Corrosion inhibitors can reduce rusting on the steel BARS. ‘Air entrainment’ is blowing little bubbles in the concrete before it sets. This helps the concrete survive the freezing and thawing of a cold climate. Blast furnace slag can be MIXED with concrete. It turns the colour into almost pure white and makes the concrete stronger.

52.	________________ is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels.(a) Structural engineering(b) Highway engineering(c) CS engineering(d) Electrical engineeringThe question was posed to me in an internship interview.My enquiry is from Analysis of Rate of Road Work in portion Analysis of Rates of Civil Engineering Drawing
Answer» Right choice is (B) Highway engineering Best explanation: Highway engineering became prominent towards the LATTER half of the 20th CENTURY after World War II. Standards of highway engineering are CONTINUOUSLY being improved. Highway engineers must take into account future traffic FLOWS, design of highway intersections/interchanges, geometric alignment and design, highway pavement materials and design, structural design of pavement thickness, and pavement maintenance.

(a standard 3% for external walls and 2% for internal walls). For ordinary building without frame, the area occupied by walls may be 10% to 15% of the plinth area.

58.	The below figure shows ___________(a) struck pointing(b) v-pointing(c) weathered pointing(d) beaded pointingI had been asked this question during an online interview.This key question is from Analysis of Rates of Plastering and Pointing in division Analysis of Rates of Civil Engineering Drawing
Answer» Right option is (d) beaded pointing To explain I would say: It is a special type of pointing which is formed by a steel or IRONED with a CONCAVE edge. It GIVES GOOD appearance, but it will damage easily when COMPARED to other types.

59.	The diameter of a domestic sewer pipe laid at gradient 1 in 100 is recommended to __________(a) 100 mm(b) 150 mm(c) 210 mm(d) 400 mmThe question was posed to me during an internship interview.This intriguing question originated from Analysis of Rates for Sanitary and Water Supply in section Analysis of Rates of Civil Engineering Drawing
Answer» The correct option is (b) 150 mm Easy explanation: A SANITARY sewer or “foul sewer” is an UNDERGROUND carriage system specifically for transporting sewage from houses and commercial buildings through PIPES to TREATMENT facilities or disposal. Sanitary sewers are part of an overall system called a sewage system or sewerage. Sewage may be treated to control water pollution before discharge to surface waters. Sanitary sewers serving industrial areas also carry industrial wastewater.

60.	Concrete solidifies due to a chemical reaction known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a strong stone-like material.(a) True(b) FalseI have been asked this question in a job interview.My doubt is from Analysis of Rates of Cement Concrete topic in chapter Analysis of Rates of Civil Engineering Drawing
Answer» RIGHT option is (a) True The best I can explain: Concrete is USED more than any other man-made material in the world. As of 2006, about 7.5 billion cubic meters of concrete are made each year—more than one cubic meter for every person on Earth. The ingredients are mixed together into a paste, a BIT like making dough for bread. The concrete is then poured into a frame. After a few hours it sets HARD.

61.	Reinforcement is often included in concrete.(a) True(b) FalseI got this question during a job interview.Question is taken from Analysis of Rates of Cement Concrete in portion Analysis of Rates of Civil Engineering Drawing
Answer» The correct answer is (a) True Explanation: 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.

62.	One differentiates between interior and exterior fireproofing. Exterior products are typically less substantial, with lower densities and lower cost. Interior products have to withstand more extreme fire and other environmental conditions.(a) True(b) FalseThe question was asked in an internship interview.The doubt is from Analysis of Rates of Plastering and Pointing topic in chapter Analysis of Rates of Civil Engineering Drawing
Answer» Right CHOICE is (b) False The explanation: One differentiates between interior and exterior fireproofing. Interior products are typically less substantial, with LOWER densities and lower COST. Exterior products have to withstand more extreme fire and other ENVIRONMENTAL conditions.

63.	The capacity of doing work by an artesian or skilled labour in the form of quantity of work per day is known as the ______________(a) over-turn(b) in-turn(c) out-turn(d) out-comeI got this question during a job interview.Query is from Estimation of Basic Rates Occurred in section Analysis of Rates of Civil Engineering Drawing
Answer» The CORRECT choice is (c) out-turn Best explanation: The out-turn of work per artesian varies to some extend according to the nature, size, height, SITUATION, location, etc. In bigger cities where specialised and EXPERIENCED LABOUR is available the out-turn is greater than small towns and country sides.

64.	Rigid pavements are generally constructed in three layers – a prepared subgrade, base or sub base, and a _______________(a) RCC(b) Concrete slab(c) Steel(d) Cement slabI had been asked this question in an interview for internship.This intriguing question originated from Analysis of Rate of Road Work in portion Analysis of Rates of Civil Engineering Drawing
Answer» The correct OPTION is (b) Concrete slab The explanation is: The concrete slab is CONSTRUCTED according to a designed choice of plan DIMENSIONS for the slab panels, directly influencing the intensity of thermal stresses occurring within the pavement. In addition to the slab panels, temperature reinforcements must be designed to control CRACKING behaviour in the slab. Joint spacing is determined by the slab panel dimensions.

65.	With flexible pavement, the highest stress occurs at the surface and the stress increases as the depth of the pavement decreases.(a) True(b) FalseI had been asked this question during an online exam.This interesting question is from Analysis of Rate of Road Work in section Analysis of Rates of Civil Engineering Drawing
Answer» Correct answer is (b) False The best I can explain: With flexible PAVEMENT, the highest STRESS occurs at the surface and the stress decreases as the depth of the pavement increases. Therefore, the highest quality material needs to be used for the surface, while lower quality materials can be used as the depth of the pavement increases. The TERM “flexible” is used because of the asphalts ability to bend and deform slightly, then return to its ORIGINAL position as each traffic LOAD is applied and removed. It is possible for these small deformations to become permanent, which can lead to rutting in the wheel path over an extended time.

66.	For frog filling, for use of cut bricks, for bonding, for uniform joints, wastages, etc. 50% extra mortar may be required.(a) True(b) FalseI have been asked this question in homework.My question is taken from Analysis of Rates of Cement Concrete in chapter Analysis of Rates of Civil Engineering Drawing
Answer» CORRECT choice is (b) False Easiest explanation: For frog filling, for use of cut bricks, for bonding, for uniform JOINTS, wastages, etc. 15% extra mortar MAY be required.

67.	To make lime plaster, limestone (calcium carbonate) is heated above approximately 50 °C to produce quicklime.(a) True(b) FalseThe question was posed to me in an international level competition.My query is from Analysis of Rates of Plastering and Pointing in portion Analysis of Rates of Civil Engineering Drawing
Answer» Correct choice is (B) False Explanation: To make lime plaster, limestone (calcium carbonate) is HEATED above approximately 850 °C to produce QUICKLIME. Water is then added to produce SLAKED lime (calcium hydroxide), which is sold as a wet putty or a white powder. Additional water is added to form a paste PRIOR to use. The paste may be stored in airtight containers.
