In accordance with the government’s “Waste to Wealth” mission, the state-owned National Highways Authority of India (NHAI) announced on 15th March that it has begun using steel slag in road construction on a trial basis. When molten steel is separated from impurities in steel-making furnaces, steel slag, a by-product of the process, is formed. Copper, steel, and aluminum are just a few of the refined metals found in slag. Slag keeps highways from breaking or changing shape over time because of its durability. Additionally, slag hinders corrosion.
Thermo-Mechanically Treated or TMT bars industry is one of the major growth sectors in India. It is one of the most important elements of any building structure, so picking the right TMT bar maker is crucial for any construction project.
The TMT bars steel industry is the cornerstone of the modern economy. The health of the economy can be easily gauged by how well its steel industry is doing. Some of the top steel producers in the world are the USA, China, EU, Russia, India, Indonesia, etc. With the evolution of technology, the steel industry went through its share of change for good.
The production of steel on an industrialized scale began as early as the 1800’s in America and England. When steel was first manufactured in 1820 in Sheffield, England, it ushered in an era of rapid social, economic and industrial development. The invention of the steam engine further fastened the process of steel manufacturing and led to unprecedented economic development.
Cement production is vital for the rapid economic development of any country. India is actually one of the largest producers of Cement. India holds the unique distinction of having an installed capacity of 500 million tons per annum with a production of 298 million tons per annum. Andhra Pradesh is the largest producer of cement followed by Rajasthan, Karnataka, Madhya Pradesh and Kerala.
Cement is the principal commodity of any foundation. Cement comes in different categories, grades and has varied properties. In India,.

Cement is the root of any construction. House construction is a big commitment in terms of money and efforts. Anyone committing to constructing their own house always has a plethora of questions, what cement to use is a consistent one. Cement is classified into a grading system. These grades are appointed on the compression strength of concrete, which is the ability to hold the load without falling apart. The strength of any cement is measured in megapascals and can be accurately determined after 28 days of setting. Different grades of cement are used for different infrastructure developments, the following are a few cement grades used extensively for house construction.
