What is the Poisson's ratio value of M30 grade concrete?
0.17
What is the theory for slump test?
Theory: Work-ability is the ease with which the given concrete mix can be mixed together, transported to the application place and can be placed/applied/compacted their within the initial setting time of cement. This property depends largely on the amount of water added i.e. water cement ratio of the concrete mix and kind of aggregates used. Generally work-ability increases with the addition of the water, however it results in the less strength of concrete. So we have to settle for an intermediate value of water cement ratio at which it may have the sufficient work-ability as well as sufficient strength.
What is the poissons ratio value for M30 concrete?
between .15 and .20
Introduction of normal consistency of cement?
the degree of wetness exhibited by a freely mixed concrete whose value is considered at hand
If Setup Corporation buys 100000 of sand rock and cement to produce redi-mix concrete It sells 10000 cubic yards of concrete at 30 a cubic yard The value added by Setup Corporation is?

What is the slenderness ratio for a intermediate concrete column?
That is depending on your KL/r value . sammy Structural engineer That is depending on your KL/r value . sammy Structural engineer
What is the constant value from cubic meter of concrete to determine weight of rebar?
There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
How do you Determine the Specific gravity of cement?
Cement is usually purchased as a powdery substance that is mixed with sand, aggregate, gravel and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for it's specific gravity. And since cement is usually not used by itself, knowing it's specific gravity is not particularly useful. A more useful question is "What is the typical density of concrete?" A rule of thumb answer is that normal cured concrete has a density of about 150 pounds per cubic foot. This includes the weight of the cement, sand, aggregate, and that part of the water that chemcially binds with the cement to form the concrete. Since water weighs about 62.4 pounds per cubic feet, concrete is about 2.4 times as heavy. Thus the specific gravity of concrete is about 2.4. If you took cement and mixed it with water, you would eventually have a hard lump of useless cement and it would also have a specific gravity of between 2 and 2.4. Ash Grove Cement from the Foreman, AR Facility normally has a specific gravity of 3.15. Depending on the source of the cement, the specific gravity may vary, but typically it will be close to this figure. Knowing the specific gravity of cement is critical when developing a mix design for concrete, because if one does not know the specific gravities of the raw materials, it is not possible to figure the proportions needed to give you the appropriate yield for a cubic yard of concrete.
What is the value of a ratio?
The value of a ratio is the total
A ratio that has a value of one?
There is not a ratio that has the value of one. A ratio is assets over liabilities.
