Types Of Building Materials Used In Construction

What Is Building Material?

Nearly 11,000 new buildings are constructed all over the world every single day. Various building materials are used for the construction of countless structures from pavements, buildings, skyscrapers to bridges, tunnels, and underwater structures. In this article, different types of building materials used in construction are discussed.


Types Of Building Materials:

1. Concrete:

Concrete is the most important and widely used building material. It is made of cement, fine and coarse aggregates, and water of suitable proportions. Chemical admixtures are also optionally used to accelerate or slow down the setting process of concrete.

The properties of concrete depend upon the quantity and mix ratio of concrete ingredients. The use of concrete has become predominant in constrution where strength and durability are prime factors.

Nowadays, most residential, commercial, and industrial buildings are constructed of concrete. There are different types of concrete used in construction such as plain cement concrete, reinforced cement concrete, prestressed concrete, etc.

Advantages Of Concrete:

i) Concrete is very strong, durable material.

ii) It has a high compressive strength.

iii) Concrete is versatile and can be cast into any shape.

iv) Great fire resistant.

v) Simple and monolithic construction.

vi) Low maintenance.

vii) Minimum weathering effect.

viii) Economical.

Disadvantages Of Concrete:

i) Concrete has low tensile strength hence should not be used as a tensioned member. However, this can be overcome by enforcing steel bars (rebars) along with concrete to provide additional strength and durability.

ii) Easy to crack.

iii) It demands strict quality control.

iii) Long curing time.

v) Brittle.

Uses:

Concrete is suitably used in the construction of buildings, bridges, dams, towers, roads, etc.

2. Cement:

Cement is a binding agent for construction materials. Cement is produced by burning at high temperature in definite mixture of calcareous, siliceous, and aluminous raw materials and crushing the resulting clinkers to a fine powder.

Cement is the most costly ingredient in concrete and available in a variety of forms. When cement is mixed with water a chemical reaction starts and as result, the powder transforms into a paste that binds all the materials with it.

The properties of cement depend on the chemical composition, manufacturing process, and degree of fineness. There are almost 16 types of cement used in construction depending upon the type of structure.

The most common types of cement used are Ordinary Portland cement (OPC) and Portland Pozzolana Cement (PPC).

Advantages Of Cement:

i) Cement is a very strong binding material. There is no other competitive substitute for this material.

ii) It is high thermal mass.

iii) It increases the strength of concrete.

iv) Easy to mix.

Disadvantages Of Cement:

i) Low tensile strength.

ii) It forms cracks in concrete.

iii) It is Costly.

Uses:

Cement is used in concrete for the construction of buildings, bridges, plastering work, dams, railway, roads, etc.

3. Fine aggregate:

Fine aggregates are the filler materials in concrete obtained from natural rocks and crushed gravels. The size of the fine aggregates is limited to 4.75 mm and below. The fine aggregates are usually inert materials that do not react with the other components of concrete. However, the silica content in the fine aggregates should be monitored to prevent the alkali-aggregate reaction which may form unwanted cracks in the structure.

The most commonly used fine aggregate was river sand which is now being replaced by Manufactured sand commonly known as M sand. The M sand is obtained by crushing the granite stone.

4. Coarse Aggregate:

Coarse aggregates are another type of filler material of a size greater than 4.75 mm. The coarse aggregates are available in various sizes from 4.5 mm to 150 mm where 20 mm is the most commonly used size. The coarse aggregates are widely used in the production of concrete and in the construction of flexible pavements (Bitumen and asphalt pavements).

The most commonly used coarse aggregates are crushed stones from quarries and gravels. However, as the world moves towards sustainability, the old concrete obtained from demolished buildings is also being used as aggregates.

5. Admixture:

Admixture is an optional component of concrete that is added to modify certain properties of the concrete to improve its performance. The volume of admixtures added to the concrete mix depends upon the need and varies from site to site. The admixtures are of two types namely – Mineral admixtures and chemical admixtures.

Mineral admixtures are solid admixtures that can replace the cement in a concrete mix. The most common mineral admixtures are fly ash, Ground granulated Blast furnace slag (GGBS), silica fume, rice husk ash, and metakaolin.

Chemical admixtures are liquid admixtures that are added to the concrete mix to modify the property of the concrete. They include

i) Accelerators – To speed up the setting process.

ii) Retarders – To slow down the setting process.

iii) Plasticisers and Superplasticizers – To improve workability without adding water to the mix thereby reducing the water-cement ratio.

iv) Air entraining agent – To create artificial sir pockets inside the concrete.

v) Water reducing admixtures – To increase the mobility of the cement particles in the plastic mix, achieving same workability at lower water contents.

vi) Viscosity modifying agents – To improve the flowability of the concrete.

6. Mortar:

Mortar is one of the oldest construction materials made using binders and fine aggregates. The most common type of binder used in mortar is cement. However, lime can also be used as a binder. The mortar used in the brick masonry should always be weaker than the bricks. This is to ensure that the failure occurs in the mortar which can be easily repaired rather than the bricks.

Uses:

They are used in masonry works, plastering, repair, and patching work.

7. Steel:

There are three types of steel used in construction.

i) Rebar steel.

ii) Structural steel.

iii) Chicken wire mesh.

a. Rebar Steel:

Rebar steel commonly known as steel reinforcement is one of the vital components of modern construction. Concrete is strong in compression but weak in tension. Steel is used in order to resist the tension that acts on the member due to bending or lateral loads.

Of all metals, steel is the most suitable reinforcement material because of the near same thermal coefficient of expansion. The thermal coefficient of concrete is 14.5 /˚C and that of steel is 12 /̊C. Due to this property of the steel, it is more compatible with concrete than other metals.

The most commonly used rebars are deformed steel bars namely Thermo Mechanically Treated bars (TMT bars) and High Yield Strength Deformed bars (HYSD) bars. These bars are circular in cross-section and have ribs protruding on the surface that improves the bonding between the concrete and steel.

Advantages Of Rebar Steel:

i) Steel has modulus of elasticity. Steel is subjected to stretch in tension without breaking and retrieve its shape after the elimination of load.

ii) Highly ductile material can withstand high impact load.

iii) High strength, durable and long lasting.

iv) Reduce thickness of concrete in RC structures.

v) Prevent cracks.

vi) Stainless steel rebars have longer life span than galvanized steel rebar by more than 5 times in different corrosive environments.

vii) Steel and concrete has equal coefficient of thermal expansion.

viii) Resistance to rough conditions is high during transporting and handling.

ix) Sustainable.

i) Very costly building material.

ii) Melts in very high temperature.

iii) Heavy in weight.

iv) Corrosion and rust problem.

b. Structural Steel:

Structural steel is an alloy of iron made using carbon and manganese. It is the building block of steel structures like trusses, steel buildings, bridges, etc. The structural steel is pre-fabricated at factories and can be easily erected at the site making the construction process faster. Using steel for construction also reduces the dead weight of the structure.

Unlike rebars, structural steel is not circular in shape. It is available in I, H, C, T, L, S, W, pipe and box sections.

c. Chicken Wire Mesh:

Chicken wire mesh is used in the construction of Ferro concrete. Ferro concrete also called Ferrocement is a type of reinforced concrete structure made up of cement, fine aggregates, hexagonal or square chicken wire mesh, and water.

First, a tightly packed wire mesh is installed over which a rich cement mortar mix of ratios 1:2 or 1:3 is applied to both sides of the wire mesh. The diameter of the holes in the wire mesh is restricted to 1 mm.
It is mostly used in repair works, slabs, manhole cover, etc.
