concrete making is just not a matter of mixing ingredients to produce a plastic maas but good concrete must satisfy performance requirements in the plastic stage and also in hardened stage.

What are the physical properties of cement?
Physical properties of cement,StrengthShrinkageDurabiltysetting timeHeat of hydrationChemical resistanceFinenessTemperature
What are the chemical properties of cement?
Portland Cement is made by baking limestone to remove the carbonate, and to this is added some gypsum (to provide sulphate) and diatomaceous earth (effectively a very finely divided silica). When curing, many complex chemicals are formed, the crystals of which give cement its strength. Silicates, sulphates, and carbonates.
Which has more dense a pound of rice or a pound of cement?
The cement is more dence
What is the specific gravity of cement?
Specific gravity of cement is 3.15.The specific gravity of cement is 3.15The specific gravity can be found out by using the bottle method.For finding specific gravity of cement kerosene is used.
How many kg of cement for 1m3 concrete?
there are 108 20kg bags of concrete to 1 cu mtr. If your making your own mix using dry mix concrete requiring cement and water, and your making a mix ratio of 5:1, then you divide 108 by 6 = 18. therefore: 18x20kg bags of cement to 1800kgs of dry concrete mix.

What are the chemical and physical properties of cement?
Three varieties of the strength of cement are measured – compressive, tensile, and flexural. Several factors affect the strength, such as water-cement ratio, cement-fine aggregate ratio, curing conditions, size and shape of a specimen, the manner of molding and mixing, loading conditions, and age. I hope it will assist you.
Is there calcium in cement?
Yes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)
