What is the difference between portland cement and pozzolan cement?
CiaNVi
There are three kinds of cement PPC, OPC. SRC.
Portland Pozzolana Cement (PPC)
The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either intergrinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions.
Pozzolana is a natural or artificial material containing silica in a reactive form. It may be further discussed as siliceous or siliceous and aluminous material which in itself possesses little, or no cementitious properties but will in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties. It is essential that pozzolana be in a finely divided state as it is only then that silica can combine with calcium hydroxide (liberated by the hydrating Portland Cement) in the presence of water to form stable calcium silicates which have cementitious properties. The pozzolanic materials commonly used are:
Volcanic ash
Calcined clay
Fly ash
lica fumes
OPC is environment friendly as well as economical
Ordinary Portland Cement (OPC-53, OPC-43, OPC-33)
OPC-43 GRADE
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.
The 43 grade OPC can be used for following applications:
General Civil Engineering construction work
RCC works(preferably where grade of concrete is up to M-30)
Pre-cast items such as blocks, tiles, pipes etc
Asbestos products such as sheets and pipes
Non-structural works such as plastering, flooring etc.
The compressive strength of cement when tested as per IS code shall be minimum 43 MPa. The physical and chemical properties of this cement are given in the table:
Physical Characteristics of 43 Grade OPC (BIS Requirement)

Sulphate Resisting Portland Cement (SRC)
Sulphate Resisting Portland Cement is a type of Portland Cement in which the amount of tricalcium aluminate (C3A) is restricted to lower than 5 % and (2 C3A + C4AF) lower than 25%. The SRC can be used for structural concrete wherever OPC or PPC or Slag Cement is usable under normal conditions.

Difference between ordinary Portland cement and puzzalona Portland cement?
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
What is the difference between cement and grout?
Grout is a substance that is used to fill gaps between tiles, such as in a shower or bathroom. Grout may be made of small aggregate, sand, and Portland cement. It may also be made of Portland cement or masonry cement and sand. There are many different types of cement, and these are usually used as an ingredient with which to make concrete and mortar.
What is the specific gravity of portland cement?
According to ASTM C188 the specific gravity of Portland cement is roughly 3.15According to ASTM C188, the specific gravity of portland cement (without voids between particles) is about 3.15. In other words, portland cement is about 3.15 times heavier than water.
Difference between opc and ppc?
Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
What is Portland cement made of?
Portland cement is made of,CaoSiO2Al2O3Fe2O3MgOAlkaliesSO3

What is the difference between white cement and plaster of Paris?
There are only slight chemical and physical differences between gray portland cement and white portland cement. These differences are due to raw material differences and sometimes, though not always, slight differences in manufacturing. The goal is to minimize the oxides (particularly iron and manganese) that impart the grayish color normally associated with portland cement. Souce:PCA (portland Cement Association)

Why do you hydrate Portland cement?
We hydrate Portland cement to use it as a binder between Fine Aggrigates & Corse Aggrigates.
What is the different between ordinary Portland cement and Portland cement?
Ordinary Portland cement is the most common cement used in the world, made from stucco, concrete, mortar and other materials. Slag cement is usually mixed with Portland cement and is the substance leftover after metal has been smelted from raw ore.
What is the difference between portland cement and type II cement?
The portland cement is used in general construction.The type-II cement is used in general concrete construction exposed to moderate sulphate action. i.e.,Concrete to be used in marine conditions.Concrete to be used in the construction of sewage treatment works.
What is de difference between ordinary portland cement and masonry cement?
Masonry cement is similar to OPC but has a plasticiser added to the cement powder. As a bag of masonry cement contains 75% cement powder and 25% plasticiser, a higher proportion of cement must be used.
What are the various types of Ordinary Portland Cement?
The various types of ordinary portland cement are,Ordinary portland cement 33 gradeOrdinary portland cement 43 gradeOrdinary portland cement 53 grade
Should Portland cement be capitalized?
According to the Portland Cement Association, portland cement should not be capitalized.
What is the specific gravity of portland cement?
