The entire globe Ramco Supergrade is favored because of its capacity to generate durable concrete in applications where the life of a concrete structure is more important. Ramco Supergrade generates less heat of hydration and is more resistant to assault by hostile fluids than standard Portland Cement. This means that it can be used in applications where other cements would fail prematurely.
It produces a stronger, more durable concrete that lasts longer. This makes it perfect for applications where you need a strong, long-lasting foundation, such as building bridges, buildings, and dams. It's also very affordable which makes it favorable for use in schools, hospitals, and homes.
The main advantage of using Ramco over other cements is its ease of use. It comes in powder form and requires only water and some time to mix together to create concrete. There are no extreme temperatures needed during mixing or storage so it's convenient for any type of application.
Ramco is highly sulfate resistant so it works well in areas with high levels of sulfur dioxide gas. This means that it can be used in places like coal mines, glass factories, and chemical plants without risk of contamination. It's also non-toxic and environmentally friendly.
In conclusion, Ramco is an affordable cement that produces a strong, durable concrete that can be used in a wide variety of applications.
PPC provides more durable concrete because it has a lower water permeability than OPC. PPC has a lower initial setting strength than OPC, but it hardens with time with adequate curing. The ultimate strength of PPC is comparable to OPC.
PPC was originally developed as a replacement for stone in building structures. It offers many advantages over natural stone including ease of installation, reduced maintenance and improved aesthetics. However, like any other concrete, PPC can be damaged by frost heave or expansive soil if used in coastal or hilly areas where freezing-and-thawing cycles may occur. Also, stone is available in a wide variety of colors and styles, while PPC comes in only a few color choices at best. Finally, PPC tends to be more expensive than stone due to the fact that it must be manufactured into shapes and sizes needed for buildings.
However, PPC is still used in small quantities for decorative purposes. It can also be used in outdoor applications such as patios and walkways because it won't crack or peel like other materials might under extreme weather conditions.
The main advantage of PPC over other types of concrete is its aesthetic quality. PPC looks like stone yet it's completely moldable once it's mixed together with water.
This is due to the fact that contemporary concrete is essentially a combination of water, aggregate (small rocks), sand, and Portland cement. However, concrete possesses properties that cement alone does not. For starters, it is less expensive. Because rock and sand are less expensive than cement alone, adding them in makes concrete less expensive than pure cement. The second reason is that it is possible to use less cement than other materials. For example, if stone is used instead of cement as a binding agent, then more stone can be used for a given project cost. The third reason is that concrete can absorb some of its weight through compression, allowing lighter materials to be used.
In conclusion, cement is cheap because it's made from fossil fuels, it has high volume but low density, and it has excellent tensile strength yet poor compressive strength.
Ramco Cement 53 grade (OPC 53): The grade is based on the cement mortar's 28-day compressive strength (as determined by IS 4031), which in this case is more than 53 MPa. This means that it is a high-strength cement.
Grade 50: The 50-year service life of concrete depends upon many factors such as the type of reinforcement, quality of aggregate, etc. Concrete with a minimum of 30 minutes age combined with well-reinforced steel bars is generally considered durable enough for most applications. Concrete that has a minimum of 100 years service life may be suitable for very stable sites or locations where thermal expansion and contraction due to temperature changes will not be a problem.
Grade 45: This is an intermediate-life cement. It should be used when the expected service life of the concrete is between 20 and 100 years. This cement has a 28-day compressive strength of at least 45 MPa.
Grade 35: This is a low-strength cement. It should only be used where the expected service life is less than 20 years because this cement does not have the capacity to resist chloride penetration for long periods of time.
The OPC classification system was developed by the American Concrete Institute (ACI). Other cements follow similar guidelines.
