What must be the slump value for different grade of concrete?
what is the slump value for M20 concrete
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.
By how many amps may a three phase motor exceed its data plate rating?
On a normal three phase motor on the nameplate there is a value in the S.F. box. This is the service factor. Depending on the size of the motor this value will vary. Smaller size motors usually have a service factor of 1.15.See related links below.
Why you install capacitor bank in electrical room?
Capacitor banks are installed in the electrical room to improve the power factor which is related to the inductive load caused by motors etc . The capacitors create a capacitive load which subtracts against the inductive load thereby improving the power factor. Most power utilities have penalties when your power factor drops below a certain value.
Why you take 0.95 as standard power factor?
When you need to calculate the estimated load or load current during initial design phase or so, you need to assume a value for power factor which is realistic. 0.95 is a realistic value.
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 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 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.
What is an N value in soil report?
N Value is the parameter indicating the compaction of the soil . N value decided from standard penetration test(spt)
Is the present value factor the exponent of the future value factor?
The present value factor is the exponent of the future value factor. this is the relationship between Present Value and Future Value.
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 relationship between present value factor and annuity present value factor?
Present value annuity factor calculates the current value of future cash flows. The present value factor is used to describe only the current cash flows.
What is the relationship between the present value factor and annuity present value factor?
Present value annuity factor calculates the current value of future cash flows. The present value factor is used to describe only the current cash flows.
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.
What is form factor in electrical?
form factor is defined as ratio between rms value and average value..
