To find the specific gravity 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.
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
1200sq. ft og cement what cost?
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.
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.
ash (pozzolan) and water...SIMPLE AS THAT.
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.
Ambuja cement in india How can I find it is original or duplicate
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.

Asphalt!2. Pozzolan cements.
To find the grade of cement, they typically use a device that looks like what a surveyor would use. They can also mark spots and use a laser to measure the incline.
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.
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.
i think you cant find it in a store so go online and get best-test 2 coat rubber cement
