Portland cement is acidic so it can result in synthetic smolders, the powder can result in aggravation or with serious introduction lung disease, and contains some poisonous fixings, for example, silica and chromium. Natural concerns are the high vitality utilization needed to mine, assembling, and transport the cement and the related air contamination including the development of gases (e.g., carbon dioxide),dioxin, NOx, SO2, and particulates. The minimal effort and broad accessibility of the limestone, shales, and other commonly happening materials utilized as a part of Portland cement make it one of the most reduced expense materials generally utilized in the course of the most recent century all through the world. Solid is a standout amongst the most adaptable development materials accessible on the planet.
This is an Ordinary Portland Cement which surpasses the prerequisites of IS: 12269-53 Grade. It is created from excellent clinker ground with high virtue gypsum. ACC 53 Grade OPC gives high strength and strength to structures in light of its ideal molecule size dissemination, prevalent crystalline structure and adjusted stage piece.
The prerequisites for high strength cement is developing as the constructional work is getting additionally requesting and differing in their applications. The compositional perspective additionally requests better completed solid structures with cantilevered heights giving way to the more customary outline designs. Thus the prior Grade 43. At the point when commonplace Portland bond is blended with water its substance compound constituents experience a development of produced responses that cause it to set. These substance responses all join the advancement of water to the crucial compound mixes. This compound response with water is called "hydration". Every one of these responses happens at a substitute time and with contrasting rates. Advancement of all these responses gives the information about how Ordinary Portland cement solidifies and constructs quality. This is the premise whereupon degree is situated.
53 Grade OPC is a higher strength cement to address the issues of the shopper for higher strength concrete. According to BIS prerequisites the base 28 days compressive strength of 53 Grade OPC ought not be under 53 MPa. For certain specific works, for example, prestressed concrete and certain things of precast solid obliging reliably high strength concrete, the utilization of 53 evaluation OPC is discovered exceptionally helpful. 53 evaluation OPC produces higher-evaluation solid at extremely sparing cement content. In solid blend outline, for solid M-20 or more evaluations a sparing of 8 to 10 % of cement may be accomplished with the utilization of 53 evaluation OPC.
53 Grade OPC can be utilized for the accompanying applications.
With the accompanying three parameters, one can comprehend why 53 Grade is viewed as better than 33 or 43 Grade cement.
1. Surface Parameter: Since the 53 Grade Cement is finely pounded when contrasted with 43 Grade Cement subsequently the Surface is higher for 53 Grade Cement.
2. Strength Parameter: 53 Grade Cement implies 53 MPa(Mega Pascal) compressive strength following 28 days of curing, when contrasted with 43 MPa for 43 Grade Cement. Subsequently the compressive strength improvement in 53 Grade Cement is higher for same curing times.
3. Pressure driven Reactions: The arrangement of Cao-SiO2 gels continue speedier when contrasted with 43 Grade Cement and henceforth higher warmth of hydration for the same solid zone. Hence 53 Grade Cement may oblige all the more curing when contrasted with 43 Grade cement.

53 Grade OPC can be utilized for the accompanying applications.
- RCC lives up to expectations (Preferably where evaluation of solid is M-25 or more)
- Precast solid things, for example, clearing pieces, tiles building squares and so forth
- Prestressed solid segments
- Runways, solid streets, Bridges and so forth.
