Question: How do you measure concrete?
Answer: Cubic feet, Cubic yards, Cubic Meter
Question: Which is stronger solid steel rod or hollow steel pipe?
Answer: On a per pound basis, steel pipe is stronger in bending and is less likely to buckle in axial compression.
Question: What is braced excavation all about?
Answer: Excavation are braced to prevent the cave-in of surrounding unstable soil.
Question: What is the meaning of soil reinforcement?
Answer: Soil reinforcement is the act of improving soil strength to enable it support or carry more load
Question: What is aggregate?
Answer: Aggregate is the component of a composite material used to resist compressive stress.
Question: What is the main reason of building collapse?
Answer: There are several reasons for building collapse. Passage of time is the main reason. Also, weak foundations, natural calamities like earthquakes, hurricanes, etc, are the major reasons for building collapse. Bombing and destruction is also another reason.
Question: State the applications of modulus of elasticity?
Answer: Modulus of elasticity is related to the flexibility of the material. The value of modulus of elasticity is related to the flexibility of the material. The value of modulus of elasticity is pretty important in case of deflection of different materials used in building construction.
Question: Difference between routine maintenance and major maintenance for school facilities.
Answer: Routine maintenance is handling the minor repairs of the school campus. Major maintenance can be total reconstruction or renovation of the school.
Question: What is soil analysis?
Answer: Soil analysis is the testing of soil to determine the nutritional and elemental composition of soil. It is generally tested for knowing the contents of nitrogen, potassium and phosphorous.
Question: What are the steps involved in the concreting process?
Answer: The major steps involved in the process of concreting are as: Batching, Mixing, Transporting and placing of concrete, compacting.
Question: What reinforcements are used in the process of prestressing?
Answer: The major types of reinforcements used in prestressing are: Spalling reinforcement, Equilibrium reinforcement, Bursting reinforcement.
Question: Why should pumping be not used in case of concreting works?
Answer: During the pumping operation the pump exerted pressure must overcome any friction between the pumping pipes and the concrete, also the weight of the concrete and the pressure head when the concrete is placed above the pumps. Since only water is pump able, all the pressure generated is by the water that is preset in the concrete. The major problem due to pumping are segregation effects and bleeding.
