CIVIL ENGINEERING MATERIAL

Assalamualaikum everyone, we are 6 members of civil engineering students from Universiti Teknologi Malaysia. We were give a task to share knowledge of Civil Engineering Material with community. So, we choose blog posting as a good platform that easy to all can reached.

The blog content will be interesting to anyone in the construction industry as the purpose is to advance and promote construction & civil engineering sectors around the globe.


WHY SELECTION OF CONSTRUCTION MATERIAL IS IMPORTANT?

    The choices for construction materials are practically infinite. Understanding the specific properties of these materials allows for the most efficient and productive application, resulting in many years of satisfaction. Civil engineers must be well-versed in the primary building materials. There are many types of civil engineering materials such as concrete, premix and steel. Also, due to growing interest in sustainable development and various incentives provided by the Government of Malaysia, the key players in the construction industry are motivated more than ever before to use materials that are sustainable or in such a way that their environmental impact is minimal. Therefore, by knowing about the material properties make the structure can be last long, economical, and minimize the environmental impact.

STEEL

WHAT IS STEEL?

    Steel is an alloy of iron and about 2% or less carbon. Pure iron is soft, but carbon greatly hardens it. Several iron-carbon constituents with different compositions or crystal structures exist such as austenite, ferrite, pearlite, cementite, and martensite where they can be combine in complex mixtures depending on temperature and carbon content.

    The steel industry has about 2000 grades of steel developed of which 1500 grades are high grade steels. There is still potential in developing new grades of steel with varying properties. The large number of grades gives steel the characteristic of a basic production material. However, the degree to which it maintains its dominant position will depend on if steel can exploit its potential by developing new higher grades and adaptable grades.

HOW STEEL CAN BE APPLY IN CONSTRUCTION?

    There are many different types of construction materials in Malaysia and all over the world. In modern construction, steel structures used for almost every type of structure. For example, like heavy industrial building, high-rise building, equipment support system, infrastructure, bridge, tower, airport terminal, heavy industrial plant, and pipe rack. Therefore, the ultimate choice of the construction material depends on the kind of building you are constructing. It is important to choose a suitable material because it affects the quality of the building and the success of the overall project as well.

    Steel structure is a metal structure where the components connect with each other to carry loads and provide full rigidity. This structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure because of the high strength grade of steel.  




WHAT IS THE BENEFITS OF STEEL?

  1. It is reusable and endlessly recyclable.
  2. Contains at least 25% recycled steel. 
  3. Enables energy efficiency in buildings and construction projects. 
  4. Strong, requiring fewer beams and providing more usable open space.
  5. Light, requiring reduced foundations.
  6. Less material implies resource saving and a lesser impact on the environment.
  7. Flexible in combination with other materials.
  8. Earthquake resistant due to steel’s ductility.
  9. Fast on-site build for prefabricated buildings.
  10. Durable.

WHAT IS THE DIFFERENCE BETWEEN STEEL AND TIMBER STRUCTURE?

Lightweight and flexible in terms of design

Easy damage

Better fire resistance

Easily exposed to fire

Sections come in desired form and length and are easily transported

Several pieces of wood

Greater span

Standard spacing

Less labor

More work to do



GREEN MATERIALS IN CONCRETE AND CONSTRUCTION

      WHAT IS GREEN MATERIAL IN CONCRETE?

Green material in concrete is made with concrete wastes which are eco-friendly so called as Green concrete. Green concrete is made of new raw materials - namely fly ash, recycled concrete aggregates and aluminium can fibres. Fly ash is a waste product from coal power plants and is commonly disposed of in ponds and sent to landfills.

In 2009, the Malaysian government launched the green building index (GBI) to encourage the construction of buildings using green technology, and introduced incentives for owners to obtain the GBI certificate for new or existing buildings. There have also been efforts to reduce air pollution and concrete has an important role to play because a significant amount of the world's carbon emissions stems from cement and concrete production. Therefore, it is important to develop green concrete that can be used in buildings and structures.


       WHY USE OF GREEN CONCRETE


1.    To Decrease the Demand for Conventional Material:


As discussed above the construction industry growth is to fast in recent year and consumption of concrete is also increased to a large extent. Because of this and limited source of mining leading to a shortage of conventional construction material like cement, aggregate. Therefore, to reduce the demand for regular construction material the green concrete is a better alternative.

 

2.     To Reduce Co2 Emission:

In conventional concrete, we use a material whose production process involves the emission of a large amount of co2 in the environment. Whereas green concrete uses waste eco-friendly material which emits too low co2 in the environment.

3.     To Recycle and Reuse the Materials:

As construction of any structure involve a huge amount of materials and also it produces a large amount of construction waste also. This waste never utilized for any other work. So, the green concrete has the idea to recycle and reuse this waste material for making concrete.


        ADVANTAGES OF GREEN CONCRETE

            1.       There is no need to change the manufacturing process 

2.       It is made from waste and recycled materials like fly ash, GGBS (Ground Granulated Blast Furnace Slag, artificial aggregates, etc. in the concrete.

3.       It decreases CO2 emission and helps in reducing the environmental pollution.

4.       It has good thermal and acid resistance.

5.       It solves the problem of recycling and disposal space required for industry waste material as it is made from residue waste material.

6.       It solves the problem of recycling and disposal space required for industry waste material as it is made from residue waste material.

7.       Green concrete compressive and split tensile strength is better with some materials compared to conventional concrete.

8.       It contributes to reducing the consumption of cement overall.

9.       It is economical compared to conventional concrete.

10.     It offers better workability than conventional concrete.


SAMPLE MATERIAL USE IN GREEN CONCRETE



CONCLUSION 

When it comes to building structures, developers and contractors have the advantage of choosing from a variety of materials to use. Generally, the decision on material choice depends on several factors including cost and performance for specific applications.

Due to growing interest in sustainable development and various incentives provided by the Government of Malaysia, the key players in the construction industry are motivated more than ever before to use materials that are sustainable or in such a way that their environmental impact is minimal.

Hence green concrete can be choosing to consume less energy and becomes economical. Uses of green concrete will not only reduce the emission of CO2 in environment and environmental impact but also economical to produce.

Moreover, green concrete designed for strength and performance during service-life of buildings or structures. It also contributes to GBI score,
has lower cement/carbon footprint per unit of concrete produced and
has potential for commercialization by providing developers and contractors with an alternative concrete that is environmental-friendly, in line with the National Green Technology Policy.
