Different types of construction materials and their Quality

                                 Study of different construction materials and their Quality




Introduction: A wide range of building materials is available for the construction of rural buildings and structures. The proper selection of materials to be used in a particular building or structure can influence the original cost, maintenance, ease of cleaning, durability and, of course, appearance. Several factors need to be considered when choosing the materials for a construction job, including:

1. Type and function of the building or structure and the specific characteristics required of the materials used, i.e. great strength, water resistance, wear resistance, attractive appearance, etc.

2. Economic aspects of the building/structure in terms of original investment and annual cost of maintenance.

3. Availability of materials in the area.

4. Availability of the skilled labor required to install some types of material.

5. Quality and durability of different types of material.

6. Transportation costs.

7. Selection of materials with compatible properties, dimensions and means of installation.

8. Cultural acceptability or personal preference.

 

Construction materials

These can be classified as

1.      Building material

2.      Roofing material

3.      Finishing material

Characteristics and Uses of Materials

Stones:

It’s a naturally occurring rough material obtain from rock and mineral particles.

The main natural and cheapest resource of stone is rocks.

Uses of Stones:

1.      Stones are used as a construction material for foundations, walls, columns and lintels.

2.      Stones are used for face-work of buildings to give good appearance.

3.      Thin stone slabs are used as roofing and flooring material.

4.      Crushed stones (course aggregates 6mm, 12mm and 20mm) are used for production of cement concrete.

5.      Crushed stones (course aggregates 40mm) are also used as ballast for railway track.

6.      Aggregate of stone is used as a road metal. 

7.      Crushed stones are used as base course for new road formation.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
