Building Construction Materials
• Building materials have an important role to play in this modern age of
technology.
• Although their most important use is in construction activities, no field of
engineering is conceivable without their use.
• Also, the building materials industry is an important contributor in our
national economy as its output governs both the rate and the quality of
construction work.
Building Construction Materials
Building Construction Materials
• There are certain general factors which affect the choice of materials for a
particular scheme.
• Perhaps the most important of these is the climatic background.
• Obviously, different materials and forms of construction have developed
in different parts of the world as a result of climatic differences.
• Another factor is the economic aspect of the choice of materials.
• The rapid advance of constructional methods, the increasing introduction
of mechanical tools and plants, and changes in the organisation of the
building industry may appreciably influence the choice of materials
Building Construction Materials
Building Construction Materials
• Due to the great diversity in the usage of buildings and installations and
the various processes of production, a great variety of requirements are
placed upon building materials calling for a very wide range of their properties:
strength at low and high temperatures, resistance to ordinary water and
sea water, acids and alkalis etc.
Building Construction Materials
• Also, materials for interior decoration of residential and public buildings,
gardens and parks, etc. should be, by their very purpose, pleasant to the
eye, durable and strong.
• Specific properties of building materials serve as a basis for subdividing them
into separate groups.
• For example, mineral binding materials are subdivided into air and
hydraulic-setting varieties
Building Construction Materials
• The principal properties of building materials predetermine their
applications.
• Only a comprehensive knowledge of the properties of materials allows a
rational choice of materials for specific service conditions.
Building Construction Materials
• The importance of standardisation cannot be over emphasised.
• It requires the quality of materials and manufactured items to be not
below a specific standard level.
• However, the importance of standardisation is not limited to this factor
alone, since each revised standard places higher requirements upon the
products than the preceding one, with the effect that the industry concerned
has to keep up with the standards and improved production techniques.

Weathering Resistance
Weathering Resistance
• Is the ability of a material to endure alternate wet and dry conditions for a long
period without considerable deformation and loss of mechanical strength.
Water Permeability
The capacity of a material to allow water to penetrate under pressure.
Materials like glass, steel and bitumen are impervious.
Fire Resistance
• Is the ability of a material to resist the action of high temperature without
any appreciable deformation and substantial loss of strength.
• Fire resistive materials are those which char, smoulder, and ignite with
difficulty when subjected to fire or high temperatures for long period but
continue to burn or smoulder only in the presence of flame, e.g. Wood
impregnated with fire proofing chemicals.
Fire Resistance
• Non-combustible materials neither smoulder nor char under the action of
temperature.
• Some of the materials neither crack nor lose shape such as clay bricks,
whereas some others like steel suffer considerable deformation under the
action of high temperature.
Refractoriness
• Denotes the ability of a material to withstand prolonged action of high
temperature without melting or losing shape. Materials resisting prolonged
temperatures of 1580 0C or more are known as refractory.
• High-melting materials can withstand temperature from 1350 0C - 1580 0C,
whereas low-melting materials withstand temperature below 1350 0C.
Chemical Resistance
• Chemical Resistance is the ability of a material to withstand the action of
acids, alkalis, sea water and gases.
• Natural stone materials, e.g. limestone, marble and dolomite are eroded even
by weak acids, wood has low resistance to acids and alkalis, bitumen
disintegrates under the action of alkali liquors.
Durability
Durability
• is the ability of a material to resist the combined effects of atmospheric
and other factors.
Weld Ability
• It is the property of a material which presents that how easily the two
pieces of material can be welded together by applying pressure or heat or
both.
Mechanical Properties
The mechanical properties of a material are those which effect the mechanical
strength and ability of material to be molded in suitable shape. Some of the typical
mechanical properties of a material are listed below:
• Strength
• Toughness
• Hardness
• Elasticity
• Plasticity
• Brittleness
• Malleability
• Ductility
• Creep and Slip
• Resilience
• Fatigue
Strength
• It is the property of material which opposes the deformation or breakdown of
material in presence of external forces or load. Material which we finalize for
our engineering product, must have suitable mechanical strength to be
capable to work under different mechanical forces or loads.
Strength
• Strength is the ability of the material to resist failure under the action of stresses
caused by loads, the most common being compression, tension, bending and
impact. The importance of studying the various strengths will be highlighted from the
fact that materials such as stones and concrete have high compressive strength but a
low tensile, bending and impact strengths.
Strength
Strength
• Compressive Strength is found from tests on standard cylinders, prisms and cube
smaller for homogeneous materials and larger for less homogeneous ones.
Strength
• Bending Strength tests are performed on small bars (beams) supported at their
ends and subjected to one or two concentrated loads which are gradually increased
until failure takes place.
Toughness
• It is the ability of material to absorb the energy and gets plastically deformed
without fracturing. Its numerical value is determined by the amount of energy
per unit volume. It unit is Joule/ m3. Value of toughness of a material can be
determines by stress-strain characteristics of material.
• For good toughness material should have good strength as well as ductility. For
example: brittle materials, having good strength but limited ductility are not
tough enough. Conversely, materials having good ductility but low strength are also
not tough enough. Therefore, to be tough, material should be capable to withstand with
both high stress and strain.
Toughness
Hardness
Hardness
• It is the ability of material to resist to permanent shape change due
to external stress.
• There are various measure of hardness – Scratch Hardness,
Indentation Hardness and Rebound Hardness.
• Scratch Hardness
Scratch Hardness is the ability of material to oppose the scratch to
outer surface layer due to external force.
Hardness
• Indentation Hardness
It is ability of material to oppose the dent due to punch of external had and
sharp object.
• Rebound Hardness
Rebound hardness is also called as dynamic hardness. It is determined by the
height of “bounce” of a diamond tipped hammer dropped from a fixed height
on the material
Ductility
• Ductility is a property of a solid material which indicates that how easily
a materials gets deformed under tensile stress.
• Ductility is often categorized by the ability of material to get stretched into a
wire by pulling or drawing.
• This mechanical property is also an aspect of plasticity of material and
temperature dependent. With rise of temperature, the ductility of material
increases.
Brittleness
• Brittleness of a material indicates that how easily it gets fractured when
it is subjected to a force or load.
• When a brittle material is subjected to a stress is observes very less energy
and gets fractures without significant strain.
• Brittleness is converse to ductility of material.
• Brittleness of material is temperature depended. Some metals which are
ductile at normal temperature become brittle at low temperature.
Malleability
Malleability
• Malleability is property of solid material which indicates that how easily a
materials gets deformed under compressive stress.
• Malleability is often categorized by the ability of material to be formed in
the form of a thin sheet by hammering or rolling.
• This mechanical property is an aspect of plasticity of material. Malleability of
material is temperature dependent. With rise of temperature, the malleability of
material
Elasticity of Materials
• It is the property of a material by which it regains its original dimensions on
removal of load or force.
Plasticity of Materials
• When we keep on increasing the load beyond limit of elasticity material retains
it molded state.
• This property of material is called plasticity.
Creep
• Creep is the property of material which indicates the tendency of
material to move slowly and deform permanently under the influence of
external mechanical stress.
• It results due to long time exposure to large external mechanical stress
with in limit of yielding. Creep is more severe in material that are subjected
to heat for long time.
Resilience
• Resilience is the ability of material to absorb the energy when it is deformed elastically
by applying stress and release the energy when stress is removed.
• Proof resilience is defined as the maximum energy that can be absorbed without permanent
deformation.
• The modulus of resilience is defined as the maximum energy that can be absorbed per unit
volume without permanent deformation. It can be determined by integrating the stress-strain
cure from zero to elastic limit. Its unit is joule/m3.
Fatigue
• Fatigue is the weakening of material caused by the repeated loading of
material. When a material is subjected to cyclic loading, and loading
greater than certain threshold value but much below the strength of
material (ultimate tensile strength limit or yield stress limit, microscopic cracks
begin to form at grain boundaries and interfaces. Eventually the crack reached
to a critical size.
• This crack propagates suddenly and the structure gets fractured. The
shape of structure effects the fatigue very much. Square holes and sharp
corners lead to elevated stresses where the fatigue crack initiates.

    Mechanical Properties The mechanicalproperties of a material are those which effect the mechanical strength and ability of material to be molded in suitable shape. Some of the typical mechanical properties of a material are listed below: • Strength • Toughness • Hardness • Elasticity • Plasticity • Brittleness • Malleability • Ductility • Creep and Slip • Resilience • Fatigue
  • 64.
    Strength • It isthe property of material which opposes the deformation or breakdown of material in presence of external forces or load. Material which we finalize for our engineering product, must have suitable mechanical strength to be capable to work under different mechanical forces or loads.
  • 65.
    Strength • Strength isthe ability of the material to resist failure under the action of stresses caused by loads, the most common being compression, tension, bending and impact. The importance of studying the various strengths will be highlighted from the fact that materials such as stones and concrete have high compressive strength but a low tensile, bending and impact strengths.
  • 66.
  • 67.
    Strength • Compressive Strengthis found from tests on standard cylinders, prisms and cube smaller for homogeneous materials and larger for less homogeneous ones.
  • 68.
    Strength • Bending Strengthtests are performed on small bars (beams) supported at their ends and subjected to one or two concentrated loads which are gradually increased until failure takes place.
  • 69.
    Toughness • It isthe ability of material to absorb the energy and gets plastically deformed without fracturing. Its numerical value is determined by the amount of energy per unit volume. It unit is Joule/ m3. Value of toughness of a material can be determines by stress-strain characteristics of material. • For good toughness material should have good strength as well as ductility. For example: brittle materials, having good strength but limited ductility are not tough enough. Conversely, materials having good ductility but low strength are also not tough enough. Therefore, to be tough, material should be capable to withstand with both high stress and strain.

    Hardness Hardness • It isthe ability of material to resist to permanent shape change due to external stress. • There are various measure of hardness – Scratch Hardness, Indentation Hardness and Rebound Hardness. • Scratch Hardness Scratch Hardness is the ability of material to oppose the scratch to outer surface layer due to external force.
  • 72.
    Hardness • Indentation Hardness Itis ability of material to oppose the dent due to punch of external had and sharp object. • Rebound Hardness Rebound hardness is also called as dynamic hardness. It is determined by the height of “bounce” of a diamond tipped hammer dropped from a fixed height on the material
  • 73.
    Ductility • Ductility isa property of a solid material which indicates that how easily a materials gets deformed under tensile stress. • Ductility is often categorized by the ability of material to get stretched into a wire by pulling or drawing. • This mechanical property is also an aspect of plasticity of material and temperature dependent. With rise of temperature, the ductility of material increases.
  • 74.
    Brittleness • Brittleness ofa material indicates that how easily it gets fractured when it is subjected to a force or load. • When a brittle material is subjected to a stress is observes very less energy and gets fractures without significant strain. • Brittleness is converse to ductility of material. • Brittleness of material is temperature depended. Some metals which are ductile at normal temperature become brittle at low temperature.
  • 75.
    Malleability Malleability • Malleability isproperty of solid material which indicates that how easily a materials gets deformed under compressive stress. • Malleability is often categorized by the ability of material to be formed in the form of a thin sheet by hammering or rolling. • This mechanical property is an aspect of plasticity of material.

    Plasticity of Materials •When we keep on increasing the load beyond limit of elasticity material retains it molded state. • This property of material is called plasticity.
  • 78.
    Creep • Creep isthe property of material which indicates the tendency of material to move slowly and deform permanently under the influence of external mechanical stress. • It results due to long time exposure to large external mechanical stress with in limit of yielding. Creep is more severe in material that are subjected to heat for long time.
  • 79.
    Resilience • Resilience isthe ability of material to absorb the energy when it is deformed elastically by applying stress and release the energy when stress is removed. • Proof resilience is defined as the maximum energy that can be absorbed without permanent deformation. • The modulus of resilience is defined as the maximum energy that can be absorbed per unit volume without permanent deformation. It can be determined by integrating the stress-strain cure from zero to elastic limit. Its unit is joule/m3.
  • 80.
    Fatigue • Fatigue isthe weakening of material caused by the repeated loading of material. When a material is subjected to cyclic loading, and loading greater than certain threshold value but much below the strength of material (ultimate tensile strength limit or yield stress limit, microscopic cracks begin to form at grain boundaries and interfaces. Eventually the crack reached to a critical size. • This crack propagates suddenly and the structure gets fractured. The shape of structure effects the fatigue very much. Square holes and sharp corners lead to elevated stresses where the fatigue crack initiates.
