  What is Corrosion in Steel Corrosion is a natural phenomenon of deterioration in steel caused by environmental interactions. A common form of corrosion is rust as it can have a diversity of negative effects on metal. The orange-brown flakes of iron oxide that form on the surface of iron that is exposed to moisture and other elements or chemicals. During the construction, the cost of TMT steel bras should be treated as a high expenditure. You cannot underestimate the risk arising from corrosion as the entire building’s strength depends upon TMT steel bars. Because The threat of corrosion is not completely safe for any metal. Proper corrosion protection is a very important part of work in construction with metals. Best Ways to Prevent Corrosion of steel In short, the best way to prevent corrosion is to prevent moisture from reaching the steel, or by using a chemical that corrodes more slowly. The following are the best ways to prevent corrosion. Galvanizing Galvanizing is a method ...

Every House Owner or Resident should be aware of Tiles and their types as they are the most extensively used building material for designing your home. You always need to know about the material type before installation. Choosing the right type of tile according to its application is a wise step before renovating or building your home or commercial space. There are tonnes of varieties in Tiles depending upon the materials, surface, installation. There are a variety of tiles like Floor Tiles, Wall Tiles, Parking Tiles available in numerous colours, shades and sizes. So, here are some tiles types based upon their availability in the market. Types of Tiles based on Materials are as follows: Porcelain Tiles:  This type of tiles is made up of finely grounded denser clay and burnt at high temperature to eliminate moisture from the tile which make the tile harder and denser. Due to its properties, it is mostly used for Flooring for densely populated areas like Commercial places, Residenti...

  Sand is one of the prior materials for Making Concrete. If the modular size of Fine Aggregate is less than 0.07 mm, then it is called Sand. So, it is used as a fine aggregate in mortar and concrete. Sand is nothing but a granular form of Silica. The Sand used in Construction should be quartz (silicon dioxide), light grey or whitish variety and should be free from silt. The Fineness or Particle size of the sand should be in such a way that when the sand passed through 2-mm IS sieve, it should be retained fully on 90-micron IS sieve. Classification of Sand: Sand can be classified on various basis. They are as follows: On the Basis of Mineral Composition:  Depending upon the mineral composition, Sand can be classified into quartz, felspar and carbonaceous types On the Basis of Particle Size:  Depending upon the Particle Size of Sand, it can be divided into three. If the Fineness Modulus (F.M) lies between 2.90 to 3.20, it is named as  Coarse Sand If the Fineness Modul...

  Wood is a thick fibrous substance present beneath the bark of various parts of a tree such as trunk, branches. It can also be defined as a natural polymeric material which practically does not age. Wood is as a natural material which is eco-friendly is widely used in Domestic and Industrial areas. Even in the World of Advanced Technology, Wooden Products have a huge demand. Wood as a Building Material falls into two major classes – Natural and Man-Made. With the advances in Sciences and Technology, a natural form of wood is being replaced by Composite Wood Materials. As the Wood comes from trees, the Classification of Wood can be classified from the Tree types. Classification of Trees: Trees are classified as Endogenous and Exogenous according to the mode of growth. Endogenous Trees:  These trees grow end wards E.g.: Palm, Bamboo Exogenous Trees:  These trees grow outwards and make structural elements. These are again classified into Conifers and Deciduous. The Wood Cla...

There are 16 different types of Cement. They are as follows: 1. Ordinary Portland Cement (OPC) :  The ingredients are mixed in the proportion of about two parts of calcareous materials to one part of argillaceous materials and then crushes and ground in ball mills. This mixture is burnt at about 1500-degree Celsius and cooled where gypsum is added to it and grounded again to the requisite fineness. Properties of OPC Cement: Fineness – 225 sq. metre/kg Soundness – 2.5mm Normal Consistency – 25% Initial Setting Time – 30 minutes Final Setting Time – 600 minutes Specific Gravity – 3.12 Mg/cubic. metre Bulk Density – 830 to1650 330 kg/cubic. metre Compressive Strength is 16 N/sq.mm & 22 N/sq.mm for 3 & 7 days respectively Loss of Ignition   Uses: This type of cement is used for general Construction Purposes where special properties are not required such as reinforced concrete buildings, bridges, pavements and can be used at normal soil conditions. This Cement type mostly u...

  What are Aggregates? Aggregates are the main ingredient in making materials of Concrete and Mortar which occupy 70-80% of Concrete Volume. Aggregate as a filler with binding material is the derived product of Sedimentary, Igneous and Metamorphic rocks and thus it is hard, strong, and durable. It can also be made from blast furnace slag. As aggregates are used in large quantities in the manufacturing of concrete, they have a significant effect on the properties of the Concrete. Therefore, it is vitally important to choose the right variety and quality before constructing. Unlike other making materials like cement and water, this does not require any special storage place and has negligible effects when exposed to various climatic conditions. Classification of Aggregates: 1) Based on Geological Origin:  They can be divided as Natural Aggregates:  These are one of the types of aggregates and are obtained from the naturally obtained rocks like Sedimentary, Igneous and Metam...

Bricks are one of the oldest building material brick and still continues to be the most conventional and leading building material because of being economical, long-lasting and easy to manage and work with. Clay bricks are most commonly used Construction Material in Masonry Construction for building up Walls, Pavements, Partitions and other load-bearing structures. How Brick is Made? Bricks are rectangular in shape and are manufactured either by using burnt clay or blend of sand and lime or it can also be made by a mixture of Sand and Portland Cement Concrete. The conventional size of a brick can be conveniently handled with one hand. The length, breadth and height of brick are interrelated as below: Length of brick = 2 × breadth of brick + thickness of mortar Height of brick = breadth of brick According to the above calculations, a standard or modular brick size should be 19 × 9 × 9 cm. The size of brick along with mortar becomes 20 × 10 × 10 cm when arranged in masonry. What is Frog ...
