BUILDING MATERIALS MCQ

1.  Construction of cavity walls as external walls to protect the building from the outside heat or cold as the hollow space between two walls act as an _______


a) Burning material
b) Insulating material
c) Destructive material
d) Building material


Solution: Properly insulated building cuts down the cost of electric burning in summer as well as in winter. Cavity walls are one of the types of thermal insulation which consists of two walls with cavity in between them.


2.__________ in a building means the free passage of clean air in a building.


a) Habitation
b) Protection
c) Sanitation
d) Ventilation

solution: Ventilation is essential in every building. Due to this, is control dust and other impurities entering in building. 


3. The termite, which are responsible for the destruction of wooden materials, are popularly known as _______


a) Red ants
b) White ants
c) Black ants
d) Big ants


solution: More than 2300 species are living ,only 4% are living in colony . The termites live in a colony and they are very fast in eating wooden and other cellulosic materials as food.


4. The treatment given to the roof of a building to prevent the roof from the leakage of water is known as _________


a) Fire proofing
b) Damp proofing
c) Termite proofing
d) Sound proofing


solution: One of the basic requirements in case of all the buildings is that the structural should remain dry as far as possible. If this condition is not satisfied, it is likely that the building may become inhabitable and hence damp proofing or water proofing is required.

Types of shallow Foundations:

Spread Footing: The spread footings are those which spread the super-imposed load of the structure over a large area.

The spread footings may be of the following types:-
(a) Single footing for a column,
(b) stepped footing for a column,
(c) sloped footing for a column,
(d) wall footing with steps and without steps, 
(e) Grillage foundation.

Combined Footing:- The common footing which is constructed for two or more columns, is called combined footing.
It may be rectangular or trapezoidal shape of a combined footing.

Strap Footing:- When two or more footings are connected by a beam, it is called a strap footing.

Raft or mat foundation:- A foundation consisting of thick reinforced concrete slab covering the entire area of the bottom of the structure, is known as raft or mat foundation.

Building construction:

Types of Foundations:
The foundations may be broadly classified as shallow foundations and deep foundations.
Shallow foundation - A foundation is said to be a shallow if its depth is equal to or less than its width.

Deep foundation -  A foundation is said to be a deep if its depth is equal to or greater than its width.

Building construction

The ability of the sub-soil to support the load of the structure without displacement or yielding, is known as bearing value or bearing power or bearing capacity of the soil. It is defined as the maximum load per unit area which the soil can resist safely.

The minimum load which will cause failure of a foundation is called ultimate bearing power of the soil. When the ultimate bearing power of the soil is divided by the factor of safety, we get safe bearing capacity of the soil.

The bearing capacity of the soil can be improved by......
(1) increasing the depth of footing,
(2) draining the sub-soil water,
(3) driving sand piles, and 
(4) ramming the granular material like              crushed stone in the soil.

Building Construction:

A building has two components,i.e. foundation or sub-structure and super structure. The foundation or sub-structure is the lowest part of the structure which transmits the load to the soil. The super structure is that part of the structure which is above the ground level. A part of the super structure, located between the ground level and the floor level is known as Plinth. The level of the floor is usually known as Plinth level and the built up covered area measured at the floor level is called Plinth area.

Define Strength of Materials:

STRENGTH OF MATERIALS also called mechanics of materials, is subject which deals with the behaviour of solid objects subject to stresses and strains.

 STRENGTH OF MATERIALS, also study of  various methods of calculating the stresses and strains in structural members, such as columns, beams and shafts.

Define construction management-

 CONSTRUCTION MANAGEMENT:

Construction management is a professional service that provides a project’s owner(s) with effective management of the project's schedule, cost, quality, safety, scope, and function. Construction management works for all project delivery methods. No matter the setting, a Construction Manager’s (CMs) responsibility is to the owner and to a successful project.
