Initial Strength: 53 Grade cement is used for fast paced construction were initial strength is to be achieved quickly. 53 Grade cement has fast setting compared to 43-grade cement. 53 Grade attains 27 Mpa in 7 days compared to 23 Mpa by 43-grade cement.
Which is best cement 43 grade or 53 grade?
OPC 43 cement shall conform to IS:8112-1989 and the designed strength of 28 days shall be minimum 43 MPa or 430 kg/sqcm. Even though 43 Grade cements’ early strength is less as compared to that of 53 Grade, with time it will attain the same ultimate strength as that of 53 Grade cement.
Why do we use 53 grade cement?
Grade 53 Cement The amount of cement is required in a smaller volume because this grade has high strength as compared to other grades of Portland cement. Grade 53 cement is mainly used in: C. 0 Bridges.
What is the grade of cement?
Grade of Cement The strength gets further measured as the comprehensive strength, which is the moulded cement in the standard cube. After 28 days of curing, it gets estimated. The measurements are in Mega-Pascal or N/mm. Generally, there are three types of cement grades; 33-grade, 43-grade, and 53-grade.

Does salt make concrete stronger?
Salt does not damage concrete, but the effects of salt can. That sounds weird, so we’ll explain. Salt does not chemically react with hardened concrete. Salt does however lower the freezing point of water, attract moisture, and increase pressure of frozen water.

Why sea water is not used in concrete?
Sea Water should not be used for preparation of any concrete (PCC or RCC). It has a salinity of about 3.5 per cent. In that about 78% is sodium chloride and 15% is chloride and sulphate of magnesium. This can react with reactive aggregates in the same manner as alkalies in cement.

What is meant by 53 grade in cement?
OPC 53 Grade cement is required to conform to BIS specification IS:12269-1987 with a designed strength for 28 days being a minimum of 53 MPa or 530 kg/sqcm. 53 Grade OPC provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure.
How can we identify 53 grade cement?
Reference IS code number should be printed on the cement bag. For example, 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.
What is the hardest cement?
PFC is an ultra-high-strength concrete whose properties can be further enhanced by incorporating steel fibers. The way in which PFC is prepared leads to very few voids in the final material, which gives it its high strength — 400 MPa can be applied to PFC before it fails, compared with 20-30 MPa for standard concrete.
What happens if you add sugar to concrete?
Sugar increases the setting time of cement up to 1.33 hrs at dosage level of 0.06% by wt of cement. There will be no effect on workability, compaction by the use of sugar as admixture in concrete. Higher long-term compressive strength is achieved in concrete by the use of sugar as admixture.

What is the smoothest concrete mix?
I suggest using an aggregate free Portland cement and sand (or silica powder if its available). The ratio is typically 1 part cement to 3 parts sand and water of course. The trick to getting a smooth final surface starts after its poured and before it sets.

Can I mix cement with salt water?
In conclusion, mixing and curing concrete in seawater increases the early compressive strength, but the seawater has a negative effect on the compressive strength of concrete at ages over 28 days.
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement.
