The Indian Cement Industry

The cement industry in India is witnessing high rate of growth due to the ever increasing demand for civic infrastructure.

The cement industry in India took off a few years after the country gained independence. Though the initial few years did not witness major progress, but since around 1970, the growth has been steady and rapid.

Ever since the Indian government took the control of the country from the British, it has been struggling with various developmental issues. Due to the enormous population of India, there has been a perpetual focus on the development of civic infrastructure as well as housing facilities. The high demand for cement, coupled with favourable Governmental policies, have been favourable factors driving the growth of the cement industry in India.

Since the past two decades, major industrial houses of the country have made forays into cement manufacture. JK Lakshmi Cement Limited is one cement manufacturer in India that has made a unique name for itself in the production of quality cement. With a production capacity of 3 million tonnes per annum, JK Lakshmi Limited has been a forerunner in India’s transition towards modern manufacturing standards. Rated as the Third Greenest Cement Plant in India, JK Lakshmi’s production facility in Rajasthan is home to the finest quality of cement that India has to offer.

Industry experts forecast that the growth pattern in cement is expected to continue further due to the increased level of construction activities taking place across India. There are various reasons for this: · The urban housing sector is expected to require investments to the tune of US$25 billion over the next five years. · Delhi, the capital of India, is home to the 2010 Commonwealth Games. · Over $5 billion have been allocated for urban Infrastructure to be spent in the next four years.

With the above reasons, it is clear that the demand for cement and other construction inputs is bound to increase. The next few years might see more investment by Indian corporate houses into the cement industry.

Plaster of Paris

You would be amazed to know that the simple looking material called Plaster of Paris (POP) has such diverse uses and applications. POP is not only abundantly available, it is also very inexpensive making it a convenient option for all income segments. POP is manufactured from Gypsum, a naturally occurring material.

Many of us might have used POP in school activities. It is often preferred by teachers for school activities as the material is safe on skin. And since it is not expensive, no one objects to it being wasted. With its short setting time, POP is perfect for creative object making by school children.

But it is in home interiors where POP is used most extensively. POP work by a skilled artisan can do wonders to the appearance of your home. Various kinds of molds are used to develop beautiful POP patterns on walls and ceilings. However it is essential to make sure that the quality of POP that you use is fine enough to avoid any occurrence of cracks in future.

Besides home interiors, another popular application of POP is in creating sculptures. The easy availability, low cost and minimal setting-time make POP an ideal substance for creating beautiful sculptures.

Nowadays Plaster of Paris is being commonly manufactured by cement companies and other companies producing construction inputs. In fact, with increased consumer demand, companies have begun distributing Plaster of Paris in small packs that are very convenient for use in minor applications.

In fact plaster of paris is a better choice.

Know the Logic behind Cement Variant Names

Cement is being manufactured in many variants today. This often confuses the layman who does not know which cement to use. Besides Portland cement, the market offers blended or PPC cement as well.

You would find many variants within Portland cement itself – 33, 43 and 53. Some manufacturers also produce cement varieties in forms such as masonry cement, high strength cement and sulphated cement.

The important thing to remember is that there is no good or bad cement, the choice should depend upon the intended application. It is interesting to note that while in the earlier times, only Portland cement used to be available, the abundant supply of fly ash resulted in the development of Pozzolana cement.

The demand from rail companies for high strength cement to be used for manufacturing sleepers put a pressure on cement manufacturers to produce special variants of cement. Such high grades of cement are also required in the construction of long span bridges, high rise structures and other structures of gigantic magnitude.

Broadly speaking:

• 33 Grade cement meets the requirement of small constructions

• 43 Grade cement is used for pre-cast concrete production and sleeper manufacture

• 53 Grade cement is used for heavy infrastructure and civil engineering applications.

One important point that must be remembered is that for most industrial and heavy applications, cement is not used directly but is rather an important input for concrete. Blended varieties of cement provide higher levels of strength and durability. While 53 Grade OPC has its own specific applications, it is not advisable to be used for ordinary structures.

Safety with cement

When cement is mixed with water a highly alkaline solution (pH ~13) is produced by the dissolution of calcium, sodium and potassium hydroxides. Gloves, goggles and a filter mask should be used for protection. Hands should be washed after contact. Cement can cause serious burns if contact is prolonged or if skin is not washed promptly. Once the cement hydrates, the hardened mass can be safely touched without gloves.

In Scandinavia, France and the UK, the level of chromium(VI), which is thought to be toxic and a major skin irritant, may not exceed 2 ppm (parts per million).
