For housing construction, that is the quality cement to be used?
The maximum usually used cement for housing construction are as under stated,
1. Ordinary Portland Cement (OPC)
2. Portland Pozzalano Cement (PPC)
Ordinary Portland cement (OPC):- 
It is the maximum well-known and famous cement and broadly used for the construction of buildings, even in each construction of work. It was Joseph Aspdin in 1824, who named it Portland cement; it was similar to Portland stone in color and excessive quality.
Usage of OPC
1) It is likewise used for prestressed concrete.
2) All kind of RCC structures, paver block, concrete blocks, OPC is recommended.
3) Suitable for all residential buildings, runways, highways, bridges, excessive-upward thrust buildings, commercials, etc.
4) Also, it is the fundamental and primary factor in mortar, plaster, and non-specialty grout.
Benefits and advantages are likely to be mentioned below,
1) Grade availability are Grade 33, Grade 43, Grade 53,
2) In much less time, It attains its power and strength
3) Speedy construction because of the excessive early power & strength
4) Highly proof against sulphate assault because of much less availability of Tricalcium aluminate (C3A),
5) Protection in opposition to alkali-aggregate response is excellent because of the presence of low alkali content,
Demerits and disadvantages are likely to be mentioned below,
1. It isn't for massive scale of construction because of better in heat
of hydration than Portland Pozzalano Cement (PPC)
2) PPC is less expensive than OPC
3) Permeability could be very excessive because of finer, and therefore decrease in durability,
4) PPC is greater long lasting than OPC,
5) PPC is greater strong concrete than OPC, because of this reason, pumping over OPC is a chunk tough.
Grade 33 and Grade 43 OPC are not to be had withinside the marketplace because of the antique grade of cement, and with-inside the gift scenario, Grade 53 OPC has changed each of them.
OPC is manufactured with the aid of using methods,
1) Wet Manufacturing process,
2) Dry Manufacturing process.
There are 3 wonderful levels of cement for production as follows,
1) Raw material acquisition
2) Clinker production,
3) Cement Grinding, packing, and distribution of cement.
Chemical Composition in OPC
1) Lime
Deficiency reasons a lower in power.
2) Silica
Adds the power, with the aid of using present process a chemical response with
calcium to shape di-calcium and tri-calcium silicates.
3) Alumina
Presence in immoderate quickens the cement placing however weakens the cement,
4) Iron Oxide
Iron oxide in better extent leads the cement to fuse in a tough function and shape clinkers.
5) Magnesia
Shall now no longer exceed 5% with the aid of using mass.
6) Sulphur Trioxide
ue to immoderate extent, makes cement is unsound.
7) Alkalies
Larger in amount ends in efflorescence.
8) Gypsum
Setting time is accelerated with the aid of using including gypsum to the cement and a small quantity is added.
Application of OPC
Type IA: It is similar to Type I, but whilst air entrainment is wanted.
Type II: For slight sulfate obstruction.
Type IIA: It is similar to Type II, but whilst the air passage is wanted.
Type II (MH): It is much like Type II, but whilst slight fieriness of hydration is wanted.
Type II (MH) A: Similar to Type II (MH), but whilst air entrainment is wanted.
Type III: For excessive starting power.
Type IIIA: Alike to Type III, but whilst air entrainment is wanted.
Type IV: For low fieriness of hydration.
Type V: for excessive sulfate opposition
