Atterberg limits tests establish the moisture contents at which fine-grained clay and silt soils transition between solid, semi-solid, plastic, and liquid states. Casagrande refined and standardized the tests, and his methods still determine the liquid limit, plastic limit, and shrinkage limit of soils.

Value of liquid limit is used to classify fine grained soil. It gives us information regarding the state of consistency of soil on site. Liquid limit of soil can be used to predict the consolidation properties of soil while calculating allowable bearing capacity & settlement of foundation.

Liquid limit is the water content where the soil starts to behave as a liquid. Liquid limit is measured by placing a clay sample in a standard cup and making a separation (groove) using a spatula. The cup is dropped till the separation vanishes. The water content of the soil is obtained from this sample.

400 mm sieve and mix thoroughly before determination of the liquid limit and plastic limit. Adjust the liquid limit device by means of the adjustment plate on the device and the gauge on the handle of the grooving tool.

The liquid limit is the moisture content at which the groove, formed by a standard tool into the sample of soil taken in the standard cup, closes for 10 mm on being given 25 blows in a standard manner. This is the limiting moisture content at which the cohesive soil passes from liquid state to plastic state.

SHRINKAGE LIMIT TEST OF SOIL(IS-2720-PART-6-1972)

Data Sheet for Shrinkage Limit Test

This limit is needed for studying the swelling and shrinkage properties of cohesive soil. The shrinkage factor helps in the design problems of structure made up of this soil or resting on such soil. It helps in assessing the suitability of soil as a construction material in foundations, roads, embankments, and dams.

The shrinkage limit (SL) is defined as the water content at which the soil changes from a semi-solid to a solid state. At this moisture content the volume of the soil mass ceases to change with further drying of the material. The shrinkage limit is less frequently used than the liquid and plastic limits.

Shrinkage calculation for hours

1. Shrinkage% = (1- (Total staffed hours/Total scheduled hours))
2. Total Staffed hours = (Total answered calls*AHT) + Avail time + productive aux.
3. Total scheduled hours = Total agent hours rostered for the day/week/month.

Shrinkage Limit Set The shrinkage limit of cohesive soils is defined as the water content at which further loss of moisture will not cause a decrease in volume. The shrinkage limit apparatus includes components necessary to run the test.

The Main Causes There are four main causes of shrinkage: shoplifting, employee theft, administrative errors, and fraud.

Shrinkage is a workforce management metric that refers to time in which agents are being paid but are not available to handle interactions. There is planned shrinkage, like agents being scheduled for staff meetings and trainings, and there is unplanned shrinkage, like an agent calling out sick or on vacation.

5 Ways to Stop the Shrinkage

1. Blow Dry Your Roots. When my hair is at least 90% dry, I pull my hair and then blow-dry the roots with medium heat.
2. Put Your Hair In a High Bun.
3. Use A Lot of Product.
4. Wait For Your Hair to Grow.
5. Embrace it!

8 Ways to Reduce Shrinkage on Natural Hair

1. Experiment with bentonite clay.
2. Or try some silicone or beeswax.
3. Try an anti-frizz serum.
4. Try an elongating stler.
5. If you use gel for a wash-n-go, make sure to “break the cast”.
6. Blow your roots.
7. Test out some natural stretching techniques.
8. Braid your hair (or pineapple it) at night.

Well, technically you can’t “unshrink” clothes, but you can stretch them back out to their original form.

Here are some tips to achieve and maintain a 5-day wash & go for natural hair:

1. Tip #1: Soaking Wet Hair.
2. Tip #2: Shingle & Coil Method.
3. Tip #3: Use a Styling Gel.
4. Tip #4: Don’t Disrupt The Drying Process.
5. Tip #5: Pineapple & Preserve It.
6. Tip #6: Revive with a Refreshing Spray.

1. Apply your styling product to soaking wet hair. No plopping here! And use A LOT.
2. Turn towards the shower and let the water run through your hair. Just a bit!
3. Now shake the crap outta your hair and VOILA! HANG!

Shrinkage is the decrease in length when your hair dries. Not only is it completely normal and a sign of healthy hair; it shows that your hair is properly moisturized and has good elasticity.

Generally speaking, the tighter your coils are the more shrinkage you could experience. Those with type 4 hair will usually see the most shrinkage over those with type 3 hair. Some people have seen shrinkage of up to 75% in their natural hair!

Shrinkage, the godforsaken extra tight coiling of the hair, normally happens after wash day, but can also occur when the weather is humid, or when a twist-out goes bad. No matter the reason, it’s always a huge eye opener when the hair transforms from its shrunken state to a more stretched pattern.

Type 3 (Curly) Type 3 curly hair can range from loose, buoyant loops to tight, springy corkscrews which have some sheen but are prone to frizz.

3A hair is made up of well-defined and springy curls that have a loopy, “S” shaped pattern. Their circumference is the size of a piece of sidewalk chalk. 3A ringlets have a fine to medium texture. This curl type benefits from lots of body and movement, but is prone to frizzing and dryness.

If your curls easily wrap around the sidewalk chalk, then you have type 3A hair. If the permanent marker is the best fit, then your hair type is 3B.

There are two ways to train your curls: finger coiling or twisting strands of hair together. This is a personal preference; experiment and do what works best for you! I usually leave the deep conditioner in my hair for 45-60 minutes. I found that it is best for me to use a protein treatment.
