What is the function of flyash in cement?
Functions of fly ash in cement,It is used as a replacement material.Low heat of hydrationGains strength more than that of the ordinary cement.
How many types of cement?
there are 3type of cement1)opc (ordnary portland cement) 2)PPC (pozolan portland cement) 3) special cement
Which cement is better OPC cement or PPC cement?
Well, both types of cements have got merits of its own. OPC is a pure type cement releasing heat energy at a faster rate & the chances of shrinkage cracks are higher. PPC is a low heat cement in comparison to OPC requiring lesser degree of immediate post concrete setting curing. OPC is not suitable for hot weather conditions. PPC is suitable for adverse weather conditions. OPC cannot be used for thick & massive elements. PPC is to some extent suitable for thicker elements. Temperature controls are better conducted on PPC.
What are the different types of cement?
Type-I - Ordinary portland cement used in general constructionType-II - Portland pozzolana cement , moderate heat of hydrationType- III - Rapid hardening cement used for quick setting worksType-IV - low heat cement, low heat of hydrationType-V - Sulphate resisting cement used in sewage linings,marine construction.
Why PPC is best RCC work?
Because ppc is most capacity of resist of heat

What type of cement should you use to put posts into the ground?
ppc cement
What is the ratio for fly ash as the cement replacement in concrete?
Replacement of cement with flyash in concrete is 20-35 % by weight for normal structures. however for special structures like dams the replacement levelscan be increased to up to 70 %. (where flyash must be ISI standards compatible or any such standards) This replacement also reduces water requirement by 2.5 % for every 10 % replacement of flyash used.
What is Opc and ppc grade of cement?
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
What is the classification of cement?
There are 3 types of cement,OPC (Ordinary Portland cement)PPC (Portland pozzolona cement)Special Cements.
Can fly ash be used in reinforced concrete and prestressed concrete?
There are experimental results showing that the flyash can be used up to 30 % as a cement replacement material. Some up to 80 % flyash has certain properties and it can be used some percent to the concrete mix as a admixture.. Proper trial mix and test shall be carried out for required strength and durability..

How are low alkali cement manufactured?
Low Alkali Cement is produced by keeping Na2o Content less than 0.6% which can be a PPC Also Low Alkali Cement is produced by keeping Na2o Content less than 0.6% which can be a PPC Also
What is the meaning of ppc cement?
Portland Pozzolana cement (PPC) is manufactured by a combination of pozzolanic materials. Pozzolana is an artificial or natural material that has silica in it in a reactive form. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker and gypsum. These pozzolanic materials include volcanic ash, calcined clay or silica fumes, and fly ash which makes around 15% to 35% of cement weight.

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.
