Which cement is best OPC or PSC?
Which cement is best OPC or PSC?
OPC takes lesser time to set than PPC. If you are construction near seashore areas, PSC must be chosen over PPC and OPC because of its excellent corrosion resistance properties.
What is the difference between PSC and OPC cement?
OPC 53 Grade means the minimum compressive strength requirement is 53 MPa at 28 days. PSC or Portland Slag cement is a kind of blended cement manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement.
Which is better OPC or PCC?
PCC gives comparable strength and durability like OPC. The basic difference between them is in the manufacturing technology. Only 65% to 80% of clinker is required to produce PCC while 95% of clinker is required to produce OPC. As a result, PCC is gaining popularity worldwide due to its environmental significance.
What is the difference between OPC and PCC?
OPC typically means Ordinary Portland Cement. This is standard concrete used for many purposes. PPC mean Pozzolanic Portland Cement. Pozzolans are siliceous material than can be added to concrete mixtures, potentially lower the mix cost without harming the performance characteristics.
What does the N and R stand for in cement?
The grades corresponds to the minimum 28th day compressive strength of cement, also referred to as cement strength classes of 32.5 Mpa, 42.5 Mpa and 52.5 Mpa respectively. While the appendage “N” refers to a class of cement with ordinary early strength, “R” Refers to those with high early strength.
Can we mix OPC and PPC cement?
Hence, both OPC & PPC can be a substitute to each other but only with a better quality control & by adopting best construction practices. So, for the construction of concrete slab both the OPC & PPC cement can be used.
Which type of cement is best?
Best Cement in India is Ultratech Cement, ACC, Ambuja Cement, Shree Cement, Ramco Cement, The India Cements Limited, Binani Cement, Wonder Cement, JSW Cement, and Mycem Cement. Followings are two best types of cement for house construction. Ordinary Portland Cement (OPC). Portland Pozzolana Cement (PPC).
Which cement is better 43 grade or 53 grade?
OPC 43 :- The 43 grade OPC is the most popular general-purpose cement in the country today. The production of 43 grade OPC is nearly 50% of the total production of cement in the country. OPC 53 :- The 53 grade OPC is higher strength cement to meet the needs of the consumer for higher strength concrete.
Where is PPC cement used?
Portland Pozzolana Cement (PPC) It can be confidently employed in construction of hydraulic structures, marine works, mass concreting such as dams, dykes, retaining walls foundations and sewage pipes. It is also suitable for use in common applications such as masonry mortars and plastering.
Which is the best cement for RCC?
There is three types of cement available in market or ordinary Portland cement (OPC) Portland slag cement (PSC) and portland pozzolana cement (PPC). OPC 53 and PPC ( Portland pozzolana cement) of all brand are the best cement for rcc roof slab construction in india,bihar and jharkhand.
Which cement is best for pillar?
Which type of cement is best for constructing the foundation? The foundation carries the load of the construction and hence needs to be strong and durable. Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.
Why is PPC cement used?
Pozzolana cement has very good resistance against sulphate attack hence is used in hydraulic structures, marine structures, construction near the sea shore, dam construction etc. PPC used in pre-stressed and post-tensioned concrete members.
Can we use PPC Cement for RCC work?
Both the OPC and PPC for RCC slabs of varying sizes and thicknesses. Thus use of OPC or PPC cement shall be properly weighed in the design mix.
Why is pozzolana added to cement?
What does a pozzolan do in the concrete? A. Pozzolans reduce bleeding because of fineness; reduce the maximum rise in temperature when used in large amounts (more than 15% by mass of cementitious material) because of the slower rate of chemical reactions; which reduce the rise in temperature.
How long does PPC cement take to dry?
Setting time of PPC us higher than OPC. Its initial setting time is 30 minutes and final setting time is 600 minutes. Its slower setting time helps to get better finishing.
Is cement stronger without sand?
In order to produce a strong, resilient concrete mix, you need to get the ratio of aggregate to sand to cement right. So if you don’t mix sand to the cement, cement will set of course but will give a lot of shrinkage crack and may not give the desired bonding.
Which cement is costly OPC or PPC?
The cost of OPC is around 300 rupees per bag which is slightly more expensive than PPC. Whereas in the case of PPC, the expensive clinker is replaced by pozzolanic Material such as fly ash hence the price of PPC is slightly less than who OPC.
What happens if you just mix cement and water?
You add some water, stir it up and pour it out. But to get the most strength from the concrete, you have to recognize when it has just the right amount of water mixed in. Too little water and the particles in the mix won’t stick together. Too much water weakens the concrete.
What is poor man’s concrete?
We have a few companies locally that offer “poor man’s concrete”. I’m not sure exactly what it is, but I’ve seen it in driveways and such. It’s a white powdery material they dump and flatten out and when it gets wet, it’s supposed to harden like cement.
Can I mix cement with water only?
Cement mixed with water alone creates a grout which can be used for repairing any damage on concrete structures. This cement-based grout mix is also used in situations where normal concrete won’t work, such as underwater concreting. Concrete is used all over the world because it is durable, economical and versatile.
What happens if you put too much cement in concrete?
Putting too much cement in concrete can result in several disadvantages. If too much is added to the mix, the concrete’s workability will suffer, and some of the aggregates won’t properly bond to the cement. If too much is used versus the aggregate, the final product’s structural integrity will likely decrease.
Which is stronger cement or concrete?
Is cement stronger than concrete? Cement is not stronger than concrete. On its own, in fact, cement is prone to cracking. When combined with aggregate materials and water and allowed to harden, however, cement—now concrete—is extraordinarily strong.
How do I calculate concrete mix?
For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield.
What is the process of mixing concrete?
The Process of Machine Mixing of Concrete: Coarse aggregates are placed in the mixer first followed by sand and then cement. Mix the materials in the dry state in the mixing machine. Normally it should be 1.5 to 3 minutes.
How many bags of concrete do I need for a 4×8 slab?
For a 4-inch slab, either eight 60-pound or six 80-pound bags are required, while for a 6-inch slab, either 12 60-pound or nine 80-pound bags are necessary.
How much does 2 yards of concrete cost?
Concrete costs $100 to $200 per cubic yard, or around $125 on average. The total cost of concrete may vary depending on location, type of concrete and how much you order….Bulk Concrete Prices.
| Cubic Yards | Price Range |
|---|---|
| 1* | $140-$200 |
