How many types of cement?
there are 3type of cement1)opc (ordnary portland cement) 2)PPC (pozolan portland cement) 3) special cement
What is fineness of cement?
Portland cement (often referred to as OPC, from Ordinary Portland Cement) fineness 300 - 500 m2/kg
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 is the specific gravity of opc-43 grade cement?
The specific gravity of Ordinary Portland Cement (OPC) 43 grade can vary slightly depending on the manufacturer and specific composition. However, as a general guideline, the specific gravity of OPC-43 grade cement typically ranges from 3.10 to 3.15. Specific gravity is a measure of the density of a substance compared to the density of water. It indicates how heavy a material is relative to an equal volume of water. OPC-43 grade cement generally has a higher specific gravity compared to water, which has a specific gravity of 1.0. It's important to note that specific gravity values can differ slightly based on factors such as cement composition, fineness, and variations in manufacturing processes. For precise information regarding the specific gravity of a particular brand or batch of OPC-43 grade cement, it is recommended to refer to the manufacturer's specifications or contact the manufacturer directly.
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 is difference between 43 and 53 grade opc cement?
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
What changes in the Raw meal composition are needed to increase 28 days compressive strength of cement clinker of opc cement at clinker manufacturing stage?
You should increase the LSF (lime saturated factor). Normal the LSF is around 95. If you increase the LSF you will proberly get a worse burnability.
What difference between psc cement opc cement?
Psc is always first choice because psc cement gives more strength than opc and also psc cement setting time is slower not that much it will give same strength in 28 days... Because of slower setting cracks will not appear or there is very less chance to appear cracks and it will requires lesser curing than opc..
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 the advantages and disadvantages between Ordinary Portland cement and Portland limestone cement?
Ordinary Portland Cement sets more quickly, and attains 85% of its maximum strength within 7 days. OPC is most valuable in large construction projects Portland Pozzolana Cement (OPC mixed with fly ash) takes longer to get to full strength, but it is more eco friendly, because it neutralizes otherwise toxic fly ash, and it is more resistant to corrosive environments. PPC can be used in most situations that OPC can.
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 difference between src and opc cement?
nothing
What is the classification of cement?
There are 3 types of cement,OPC (Ordinary Portland cement)PPC (Portland pozzolona cement)Special Cements.
