What is the Poisson's ratio value of M30 grade concrete?
0.17
What are advantages of concrete slump test?
when we pour any material i.e, sand or gravel or any other material on ground it takes conical shape . Because, every particle has its own angle of internal friction. To maintain its angle of internal friction it takes the shape of the cone. so the reason why we prefer the slump test apoparatus in that shape.
What is the value of the long term modulus of elasticity of grade 35 concrete?
According to IS 456-2000 the value is square root of 5700fck
Steel reinforcement bars add stability to concrete walls Do they also enhance the insulating value of concrete?
Concrete does not have a very good insulating value, and neither does steel. The mixture of the two will add structural stability to what you are building, but it (commonly) will not enhance the concrete's insulating value.
What is the R-value of Normal Weight Concrete per inch of material?
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
What are required slump height of M20 for different concrete structure?
Required slump height of M20 for different concrete structures, are normally calculated by the required slump value, which would come out to be 100 lits.
What is the Poisson's ratio value of M30 grade concrete?

Why is compacting factor test is better than slump test for concrete?
compaction factor test is better than slump test,because compaction factor test should have own compaction wight,so correct value will be find out from compaction factor test.........
What is compaction ratio of concrete?
The Compacting Factor = Weight of partially compacted concrete/Weight of fully compacted concrete.The weight of fully compacted concrete can also be calculated by knowing the proportion of materials, their respective specific gravities, and the volume of the cylinder.It is seen from experience, that it makes very little difference in compacting factor value, whether the weight of fully compacted concrete is calculated theoretically or found out actually after100 per cent compaction.

How do you record a slump test result?
The slump test gives fairly good consistent results for a plastic-mix. This test is not sensitive for a stiff-mix. In case of dry-mix, no variation can be detected between mixesof different workability. In the case of rich mixes, the value is often satisfactory, their slump being sensitive to variations in workability.
What is the essence of slump test as used in civil engineering?
Slump test is the most commonly used method of measuring workability of concretewhich can be employed either in laboratory or at site of work.It is seen that the slump test gives fairly good consistent results for a plastic-mix. This test is not sensitive for a stiff-mix. In case of dry-mix, no variation can be detected between mixes of different workability. In the case of rich mixes, the value is often satisfactory, their slump being sensitive to variations in workability.

Concrete does not have a very good insulating value, and neither does steel. The mixture of the two will add structural stability to what you are building, but it (commonly) will not enhance the concrete's insulating value.
How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
What is PF69 mean in coin value?
PF-69 is not a value, it's a grade. But it does affect the value, the higher the grade the more value a coin has. A PF-69 coin is one grade below a "Perfect" proof coin.
What is the definition of value in grade words?
the definition of value (in social studies i think) in 5 grade words:what u believe in
