Andhra Pradesh is the largest producer of cement followed by Rajasthan, Karnataka, Madhya Pradesh and Kerala.
=&0=& can be a tricky tale, it has to be concrete and sturdy for long-lasting structures. Certain factors determining the need to =&1=&are quality, texture, impurities, and soundness. Soundness is one of the major factors that need to be attended before buying cement in bulk. Underneath we have explained what does soundness mean and causes it becomes unsound, read through:
=&3=&
The soundness of concrete is the property of solidified bond glue experiencing an extensive change in volume in the wake of setting without postponed ruinous development. This dangerous development is caused by intemperate measures of free lime or magnesia. This adjustment in volume may cause a crack and break down of cement. The soundness of the bond can be checked by utilizing the Le-Chatelier’s apparatus. Soundness is the only volumetric difference in the concrete. Presents of chemicals, for example, CaO, MgO will respond with the water shown in the bond glue and it will expand the volume of cement glue while solidifying. It might make breaks in the building maintain a strategic distance from that it is necessary to discover the soundness of concrete before utilizing that. It might fluctuate to each kind of bond even for each clump. Soundness ought not to surpass 10 mm for OPC.
The solidified property of cement or mortar is for the most part affected by the property of concrete. Ordinarily, once the solid or mortar get solidified, they don’t go under extension or constriction. i.e. the volume of cement or mortar does not change once they are set. The soundness of the bond is a critical property. Soundness alludes to the capacity of bond glue to hold its volume after it has to get solidified.
After the drying of bond mortar or solid, it ought not to experience any obvious change in volume. On the off chance that it does, it will cause extension/compression on drying. Therefore, there are odds of improvement of breaks. Pointless development or constriction happening because of deterioration is called an unsound bond. The unsound bond can make genuine inconveniences the sturdiness of structures when such concrete is utilized. A decent unsound bond never goes under any volume changes once it sets and there is no extension or withdrawal in the wake of drying.

Ordinarily, because of the nearness of free lime (CaO) or magnesia (MgO) in bond, the glue extends after it has set which likewise impedes its quality. Hence, Portland bond details constrain the nearness of free lime and magnesia in concrete substance. Amid the assembling procedure of concrete, crude materials are nourished into the oven. Different crude materials like lime (Cao) and some acidic oxide blended inside the furnace. On the off chance that consuming and cooling forms are not acceptable, the abundance lime will stay in a free condition. This hard-consumed lime hydrates gradually and slaked lime involves the bigger volume than the first free calcium oxide. The moderate hydration process thusly influences the solidified property of mortar or cement. The distinction of hydration rate between free lime and slaked lime prompts a change in the volume of mortar or cement. The bond which shows this sort of development is depicted as unsound.
A bond can likewise be unsound because of the nearness of magnesium oxide (MgO), which responds with water in a way like lime. The third compound at risk to cause extension is calcium sulfate (CaSo4). For this situation, calcium sulfoaluminate is shaped inside the oven. It might be reviewed that a hydrate of calcium sulfate – gypsum is added to concrete clinker keeping in mind the end goal to avert streak set. In any case, if gypsum is available in an abundance sum it will respond with C3A amid setting and unsoundness as a moderate development will come about. Thus, as far as possible entirely the measure of gypsum can be added to the clinker. The breaking points are well erring on the side of caution the extent that the threats of unsoundness are concerned.

As mentioned above portland cement is one of the =&6=&
The very first civilizations that included =&0=& for construction were the Assyrians and Babylonians. Earlier, stones have been invariably used as a construction material with lime as the binder. Archaeological findings suggest that Egyptians used gypsum and lime as a constructional material in the world-famous pyramids. Isaac C. Johnson in 1845 was the first to find cement by burning limestone and clay together at a very high temperature and forming a clinker. This cement was later used as a prototype for the modern Portland cement, which is one of the =&1=&in recent times.
After its invention, a gradual improvement in the quality of =&0=& was achieved by researchers in the U.S.A., U.K., France, and Germany.
Cement is an adhesive material, capable of bonding particles of solid matter into a compact sturdy and durable mass. Cement has various types, one such classification is hydraulic and non-hydraulic.
- Non-Hydraulic Cement: It does not harden in water as non-hydraulic lime or material like Plaster of Paris is unstable to set in water.
- Hydraulic Cement: It does set and harden in water easily, hydraulic cement gives surface stability and sturdiness it requires. This cement is only required for big constructions and is the kind of cement bought directly from the manufacturer, as to attain it at cheaper rates. E.g. Portland cement.
Bulk Cement can be assembled either from natural stones or artificially, with the help of calcareous and argillaceous materials. Some of the natural cement are Roman cement, Pozzolana cement, and Medina cement. Portland cement and other special cement classify as artificial cement.

Cement is the principal commodity of any foundation. Cement comes in different categories, grades and has varied properties. In India,. Cement is differentiated mostly on the quantity requirement, as Trade or non-Trade. To understand how to purchase non-trade cement its first important to address the meaning and difference between the two.

Ordinary Portland cement (OPC), Grade:43 : It is an affordable grade and strengthens nicely in a 28 day time frame. Grade 43, as the name suggests attains the compression strength of 43 MPA(megapascals) eventually. It is a moderate quality cement, dispensing decent strength, satisfactory for residential construction. It is mostly used for wall plastering works, Non-RCC structures, pathways, etc, and adheres to IS 12269 standard code.
Ordinary Portland Cement (OPC), Grade 53: Residential construction can be an elongated process, housing societies or residential complexes which are undertaken by construction groups need fast-paced construction. These houses are to be handed over in an appointed time to their investors. To attain faster results grade 53 is preferred, it’s MPA is achieved quickly. It attains 27 MPA in 7 days compared to 27 MPA by 43-grade cement. It is majorly used in RCC and prestressed concrete of higher grades, cement grouts, instant plugging mortars, etc, and adheres to IS 8112 standard code.
Portland Pozzolana Cement (PPC) : High-res buildings or structures, where n-number of people are living in close proximity, can have 15-25 floors at one time and are referred to as mass concreting structures. These structures need immense strength and security. PPC is an accurate choice for such constructions, it has higher degree fineness, impermeability, and corrosion resistance quality which densifies overtime making the structures more reliable. The initial setting time of PPC is low however it gains strength with time. It adheres to IS 1489 standard code.
Portland Slag Cement (PSC): The world is divided over different regions with different climatic conditions, cement manufacturing is done considering these diverse needs. PSC is preferred in areas where structures are prone to sulfate and chloride attacks.It has a sturdy corrosion resistance from saltwater and is widely used in coastal regions or areas exposed to water treatment plants and sewage disposal. It adheres to IS 455:1989 standard code.
White cement : It is a white color cement, unlike others that are grey. It’s mostly used as the last layer before the paint or for decorative designs. It is also used to fill gaps between wall tiles or bathroom fixtures, leaving a smooth and finished texture. The manufacturing process of white cement is more complicated and different from ordinary Portland cement. It adheres to standard code IS 419:1967.
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.
Cement is an inevitable part of any construction and is used in high quantities for structure building. The strength of any structure depends on several factors, cement quality being one of the most important one. The longevity of a structure is decided at the initial steps of construction with the help of architectural maps, brick quality, cement quality, etc. Before cement procurement, it is important to determine the quality. Cement is a structure binding agent and any negligence in its quality can lead to the whole structure coming crashing down. Certain defined techniques have proven to be beneficial in determining the cement quality. Let’s discuss them:
