Q.2 What is the difference between BC and SDBC ?
Ans BC- Bituminous Concrete
SDBC- Semi Dense Bituminous Concrete
Ans BC- Bituminous Concrete
SDBC- Semi Dense Bituminous Concrete
Q.3 What is the basic difference in absorption, adsorption?
Ans.Absorption is a phenomenon where an atom, molecule particle or ions enter any bulk phase like gas, solid or liquid. Absorption refers to the phenomenon where energy of photon is transferred to other entity.
Adsorption is quite same to absorption. It refers to the surface rather than a volume. Adsorption occurs when the gas or liquid solute accumulates on the surface of solid. A substance diffuses or mixed in liquid or solid to form a solution.
Q.4 What is the meaning of Fe415 ?
Ans Fe415 refers for Ferrous material ie iron from which the reinforcement steel bars are manufactured. The number 415 indicates that the Yield Strength (tensile strength when it is subjected to elongation) of steel is 415 N/mm2.
The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated in grades of Fe250, Fe415 or Fe500 depending on their Yield Strength.

Q.5 How are the freeway bridges built?
Ans.The traffic that is likely to go over the bridge at a time is estimated and the cement, rocked with rubber stanchions is placed over the freeway to build a bridge. Off-ramp from freeway to the bridge and on-ramp from the bridge to the freeway are constructed. Cement slabs are placed one by one to build a platform.

Q.6 A flat slab is capable to withstand ?
Ans..concentrated loads.
Ans..concentrated loads.
Q.7 An R.C.C. column is treated as long if its slenderness ratio is greater than?
Ans..50
Ans..50
Q.8 Difference between routine maintenance and major maintenance for school facilities?
Ans..Routine maintenance is handling the minor repairs of the school campus. Major maintenance can be total reconstruction or renovation of the school.

Q.9 Cantilever retaining walls can safely be used for a height not more than?
Ans..6 m
Ans..6 m
Q.10 State the applications of modulus of elasticity?
Ans...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.
