What is the importance of specific gravity for cement quality?
To find the specific gravity of cement
What is the soundness of cement?
soundness is nothing but volumetric change of the cement .Presents of chemicals such as CaO,MgO will react with the water present in the cement paste and it will increase the volume of cement paste while hardening.It may causes cracks in the building to avoid that it is necessary to find the soundness of cement before using that.It may vary to each type of cement even for each batch.Soundness should not exceed 10mm for OPC.
What is bulkage of cement?
when water is added to the cement,cement volume decreases due to removal of air from cement particles. this reduction in cement volume is the bulkage
What is cement cement price?
1200sq. ft og cement what cost?
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.
Are iron copper zinc manganese potassium magnesium sodium and calcium present in a pozzolan?
These elements are not typical for pozzolan.
What is the origin of cement and where it was first used in primitive form?
The first cements existed at least as far back as the civilizations of Greece and Minoan, some 500 BC or so. These were composed of local Pozzolan materials, calcined and mixed with Calcium Hydroxide (burnt lime) to make a cement.
What material is used to build the pantheon?
ash (pozzolan) and water...SIMPLE AS THAT.
What is pozzolanic cement?
Pozzolanic cement is a cement which consists of pozzolanic materials like fly ash, volcanic ash, pumicite,etc.,A Pozzolan is any material which in the presence of lime and water will react hydraulically to form a cemented massContains pozzolanic materials of 10-95% by weight.Pozzolanic cement can be made from 95 % recycled materialsprovides many improved performance ove OPC. (ordinary portland cement)It is generally used now a daysLess heat evolved when compared to OPC.
How can you find ambuja industries cement in india is original or duplicate?

What is pabbleradiance pool finish and what is the different from jewel scape pool finish?
Find out if these are premix products blended and bagged by a particular manufacturer and get info from them. Plastering pools for 36 years I have never heard of either one. They may be some plasterers made up name for basically generic ingredients.....cement, pebbles, quartz....give it a fancy name. The best pool surface uses polymer and pozzolan modified cement with true dolomitic marble sand. These last 25-50 years.

Where can i find waterproofing cement?
You can find waterproof cement in many places. Try your local hardware store or try Grail Coat. They have a website so you can definitely check it out and see the different varieties they have.
Why is fly ash used in construction?
As pozzolan greatly improves the strength and durability of concrete, the use of ash is a key factor in their preservation and add to the concrete's final strength and increase its chemical resistance and durability.It can also increase workability of cement while reducing water demand. The replacement of Portland cement with fly ash also reduces the greenhouse gas foot print of concrete, as the production of one ton of Portland cement produces approximately one ton of CO2. Since the worldwide production of Portland cement is expected to reach nearly 2 billion tons by 2010, replacement of 30% of this amount by fly ash could dramatically reduce global carbon emissions.
