What is the compaction factor for medium degree of workability?

What is the compaction factor for medium degree of workability? Explanation: The compaction factor for medium degree of workability is . 92 and . 78 is the compaction for a very low degree.

What is the compaction factor for low degree of workability?

Explanation: The compaction factor for low degree of workability is . 85 and . 95 is the compaction for the high degree.

When compaction factor is 0.92 then the degree of workability?

A compaction factor of 0.85 represents a mix of poor workability, 0.92 represents medium and 0.95 good workability.

What factors affect workability?

What is compaction MCQS?

Compaction is the process in which the free spaces are collected in the large memory chunk to make some space available for processes.

Compaction Factor Test for Concrete || Test for Workability of Concrete#3

When compaction factor is 0.8 then the degree of workability of concrete is designated as?

For a good workability, compaction factor must be between (0.7 - 0.95). Extremely low - 0.65 to 0.68. Very low - 0.75. Low - 0.83 to 0.85.

What is the relation between workability and compacting factor?

The relationship between workability and compacting factor is higher the compaction factor higher is the work-ability. Theoretically maximum value of the compaction factor can be 0.96 to 1.0.

What is the compaction factor?

The compaction factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete. It shall normally to be stated to the nearest second decimal place. Compaction Factor Value= (W1-W) / (W2-W)

When compaction factor is 0.84 then the degree of workability of concrete is designed as?

Explanation: Compaction factor should lie between 0.95 and 1 for high workability. Hence compaction factor of 0.88 indicates that the workability of the concrete mix is Medium.

What is the range of water in M20?

What is the range of water in M20? Explanation: The range of water for M20 (1:1.5:3) is 26 to 30 liters with a weight of 404kg of cement.

What is meant by workability of concrete?

What is the Workability of Concrete? Workability of Concrete is a broad and subjective term describing how easily freshly mixed concrete can be mixed, placed, consolidated, and finished with minimal loss of homogeneity.

How is compaction factor calculated?

Divide the weight of the dry soil by the volume of sand required to fill the hole to find the soil density in pounds per cubic foot. For example, if the weight of the soil is now 1 lb. and the volume of the sand in the hole is . 5 cubic feet, the density would be 1 lb/.

What is compaction of concrete?

Compaction is the process which expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of concrete. It increases significantly the ultimate strength of concrete and enhances the bond with reinforcement.

What is meant by Workability?

1 : capable of being worked a workable material. 2 : practicable, feasible a workable system.

What is compacting factor ratio?

The compacting factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete.

What is compaction factor of soil?

Soil compaction factor – the ratio of the actual density of the soil (soil skeleton) in the embankment, to the maximum density of the soil (soil skeleton).

How the workability and strength related to each other?

Workability and strength of concrete are inversely proportional. Strength of concrete decreases with increase in workability of normal concrete affecting the durability of concrete.

Is code for compaction factor test?

Compaction Factor Test of Concrete: Procedure Lab Report pdf as per IS Code: 1199-1959.

What is the ratio of the component in grade M20 concrete?

Generally, M20 grade is used. The ratio of cement: fine: coarse aggregate for M20 is 1:1.5:3. For M10 it is 1:3:6, M15 it is 1:2:4 and M25 it is 1:1:2.

Which of the following introduces an error of about 1 in 1000 if 20m chain is used?

Now we want to find the difference in height of chain ends for which 1 in 1000 or 20 mm in 20 m chain length will produce. 0.02 = h^2/(2 x 20), h = 0.9 m, So, option B along with A, C options is correct.

What is compaction answer?

Compaction is a process of increasing soil density and removing air, usually by mechanical means. The size of the individual soil particles does not change, neither is water removed. Purposeful compaction is intended to improve the strength and stiffness of soil.

What is compaction select one?

Compaction is the process in which the free spaces are collected in the large memory chunk to make some space available for processes.

When the degree of consolidation is 50 the time factor is about?

For the consolidation of 50%, find the time factor. (T_v)_{50}=\frac{π}{4}(\frac{50}{100})^2=0.197.
