How can we identify 53 grade cement?

Particular IS code number should be printed on the cement bag(i.e. )if you have ordered OPC 53 grade cement, then “IS-12269-1987” should be printed on the cement bag, and if you have ordered Portland Pozzolana Cement (PPC), “IS 1489-1991” should be printed on the cement bags.

How is grade of cement decided?

The grade of cement is generally differentiated in terms of indicates the strength of cement. The strength of cement is generally measured as compressive strength. Compressive strength is the strength of cement molded in a standard cube, after 28 days of curing.

Why it is called 53 grade cement?

OPC 53 means, It gives compressive strength of 53 N/mm when it is tested for compressive strength as per Indian standard guidelines. 53 Grade Cement. OPC 53 grade cement has better quality, strength, and less setting time compared to 33 and 43 grades of cement.

What is difference between 43 and 53 grade cement?

53 Grade OPC cement is Used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria. 43 Grade OPC Cement is commonly used for plastering works, Non-RCC structures, pathways etc where initial setting time is not of importance.

What is the meaning of 53 43 and 33 grade of cement?

The initial strength of 53 grade cement is higher than 33 grade or 43 grade cement. The strength of 53 grades does not increase much after 28 days due to initial strength increases, while 33 grade and 43-grade cement are gaining strength even after 28 days.

33 Grade vs 43 Grade vs 53 Grade of Cement

Which is better OPC or PPC?

PPC cement is generally used for plastering, brick masonry and waterproofing works. PPC has a lower heat of hydration and it is prone to fewer cracks compared to OPC. PPC has lower strength than OPC but PPC provides better workability and finishing than OPC. PPC provides greater resistance to chemicals.

What is OPC and PPC cement?

PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) These two type of cement differs from each other in terms of component, strength, heat generation, the percentage of several components, durability, grades, cost, eco-friendly nature, application, setting time, curing period etc.

Which cement is OPC 53?

53 Grade Ordinary Portland Cement (OPC 53)

Which is better OPC 43 and OPC 53?

OPC 53 sets quicker than OPC 43 and has a quite low initial setting time. It is used in structures where rapid strength gain is required like large load bearing structures like bridges, huge buildings, etc. OPC 43 on the other hand doesn't set so quickly and has a normal initial and final setting time.

Which cement is OPC 53 grade cement?

Ordinary Portland cement (OPC) 53 Grade is used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria.

How do you identify cement?

You can identify good cement by its gray colour with a slight green shade. 3) Lumps – In cement, lumps are formed due to absorption of moisture. Good cement has no lumps. 4) Temperature – If you push your hand inside a bag of good cement, you should feel a certain coolness.

How do you test cement?

Cement Adulteration Test

To check the quality of cement, you can take a pinch of the construction material and rub it between your fingers. If the material feels smooth on your skin, you should go ahead and use it. However, if the cement feels rough or gritty, it could be an indicator of excess sand.

What is OPC cement?

Ordinary Portland cement (simply called ordinary cement) refers to the hydraulic binding material ground by mixing Portland cement clinker, 6% ~ 15% blended materials, and appropriate amount of gypsum, code-named P• O.

Which rod is best for roof?

Which is costly OPC or PPC?

Cost. 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.

Is UltraTech Super OPC or PPC?

UltraTech Super is a PPC grade cement. It is a finely blended cement manufactured using latest technology. It produces high strength concrete which is durable and highly resistant to wet cracking and thermal cracking.

Which cement is best PSC or PPC?

PSC cement is the better then the PPC. The ultimate strength of PSC is high. Chloride & sulfate attack is very dangerous for any type of structure, PSC is only cement who react better opposite to the Chloride and Sulfate. PPC is not suitable for coastal and sea shore area.

Can we use PPC cement for RCC work?

OPC cement can also be recommended for the construction of columns, beams, etc. On the other hand, PPC cement is made up of 75-77% cement clinker, 20% flyash and 3-5% gypsum. They are commonly used for small residential construction. PPC is recommended for brick masonry, plastering, tiling and waterproofing works.
