NUMERICAL ON SOIL CLASSIFICATION 


1. Numerical of Gopal Ranjan and AS RAO Book.

Given Details as shown below in the numerical. We need to classify the soil as per indian Standard.

Sieve Size (mm)Percent Finer
Sample 1Sample 2Sample 3
4.75100.001001100
2100.0099.25100
199.8098.7599.9
0.4599.659899.7
0.21298.9554.1590
0.1597.557.681.5
0.07596.85663
wL23.00'----'---
wp16.77'----'---
IP6.23Non PlasticNon Plastic

Sample 1. 

A. Look at the % finer in 0.075 mm sieve (75 micron sieve) 

      Which in this case is 96.85 (marked Red) As this fraction is greater than  50 % so soil is fine grained soil and we need to look in to Liquid Limit and Plastic Limit of the soil sample. 


B. Liquid limit and Plastic limits are given. 
          wl=23.00
          wp = 16.77 
          Plasticity Index = 6.23 (Given) 

In the plasticity chart the Liquid Limit and Plasticity Index will be plotted somewhere marked hatched in the image. 



So for the Sample Dual Symbol will be used. 

Sample will therefore will be classified as CL-ML. 


Sample 2 

A. % Finer of 75 micron sieve Size is 6.00 which is less than 50 %. Hence sample will be coarse grained soil. 

B. % finer than 4.75 mm is 100.00 (Given) which is greater than 50 %. Hence sample will be sand. 

C. Now we need to look in to the Grain Size Curve.

Grain Size Curve is as Follows :-

It can be easily observed from the Grain Size Distribution Curve that 

for Sample 2 :- 
 D60 = 0.22 mm. D30 = 0.19 mm, D10 = 0.16 mm

Cu = D60/D10 = 0.22/0.16 = 1.38. (Which is less than 06. 

Cc = (D30*D30)/(D60*D10) = (0.19*0.19)/(0.22*0.16)= 1.03 

For a soil to be well graded Cu > 6 & 1<Cc<3. Both these two conditions should satisfy simultaneously. 

so First Part is SP. 

Also % Finer passing 75 micron is 6 % which lies between 5% and 12 %. However it is also given that fines are Non Plastic. SM will be the classification. 

Hence Sample 2 will be SP-SM. 


Sample 3 


Step 1. More than 50 5 of soil is passing through 75 micron sieve. (63 % Given). Soil is either clay or silt. 

Step 2. Liquid Limit and Plastic Limit is not Given and soil has been described as Non Plastic. So Classification will be termed as ML

What is the difference between Marble and Granite ?



All the site Engineers use to face the same question during the construction phase. Here we will try to give few points of difference between marble and granite. 


Point No. 01 :- 


Granite is a silicious rock which implies that silica predominates in this stone. 
Marble is a Calcareous Rock which implies that Calcium Carbonate predominates in this stone.

Point No. 02 :- 


Granite due to its chemical composition is not affected by the process of weathering.  
Marble however is not that durable. Due to presence of Calcium Carbonate its durability depends on the surrounding environment. For example Taj Mahal in Agra is made up of White Stones which are believed to be deteriorating due to pollution. 

Point No. 03 :- 


Granite is more strong. Compressive strength of Granite varies from 75 N/mm2 to        127 N/mm2. 
Marble is comparatively less stronger. Its compressive strength is around 71 N/mm2. 

Point No. 04 :- 


Carving (नक्कासी ) is difficult in case of granite and the reason can be better understand in relation with the Point No. 03 Above. 
Carving is easy in case of Marble.  Probably this is the reason of choosing Marble in Historic Structures. 

Point No. 05 :- 


in Terms of Origin, Granite is an Igneous Rock. 

Marble is a Metamorphic Rock.

Point No 06 :- 


In General, Granite is more costly compared to Marble. 



These are the basic differences between Granite and Marble.

SSC JE MARKS DISTRIBUTION ACROSS VARIOUS SUBJECTS IN OBJECTIVE PAPER OF 2016


We would like to welcome all the visitors who are currently reading this. Efforts are once again being made to analyse the objective paper of SSC Junior Engineer Exam 2016. Same efforts was also made for the objective paper of SSC JE 2012 but after that such efforts were not made by the Admin Team due to the various constraints. 

SSC JE 2017 is scheduled on 23 to 25 Dec 2017 and you all must be trying your level best to achieve the required cutoff percentage. For those, who have completed all the subjects already, it will be very easy to crack the exam. But still few peoples must be trying to cope up the time, which had been wasted by them. As we also belong to the second category of students, so we have an idea of their requirements. ☺ 

An analysis has been carried out by the Admin team for the objective paper of 2016. It is a well understood fact that pattern of paper remain more or less same so this type of marks distribution will help the students in prioritizing the subjects. 

Hope it is going to help you to either begin from the scratch or improve your position if you are already in the race. 

Please comment and share if enjoyed the post and content. Author will be highly indebted of your kind gesture.

Few Points to Ponder :- 

1. Survey :- Although majority of Questions asked were directly from Gupta and Gupta but one question was also asked from Transition curves. Made Easy Notes will help in this regard.
2. Soil Mechanics :- Only 04 Questions were asked from this subject. It seems that this evergreen subject is loosing its charm. But from practical aspects too, soil mechanics is not a very important subject for the jobs where you have to majorly deal with the construction activities. But still you must focus on this subject.
3. Fluid Mechanics :- One question was asked from pressure flow in pipes. Such question are bit harder side as far as Junior Engineer is concerned. Rest of the questions were easy in nature.
4. Open Channel Flow :- Only one question was asked from open channel flow and that too from Hydraulic Jump. 

5. Irrigation Engineering : Only 2 questions. Gupta and Gupta Level. 

6. Highway Engineering ;- One Question from Geometrical Design. 

7. Concrete Technology. : Questions were easy but you need to remember them. Level Gupta and Gupta. 

8. RCC :- Total 09 Questions. Majority of them were based directly on the provisions of IS 456 :2000. One question was also asked from prestress losses. 

9. Steel Structure : 09 Questions from rivets. 

10. Environment : 02 questions. That too from air pollution only. 

11. Building Material : Easy questions. You need to remember them. Gupta and Gupta will suffice. 

12. Estimation and Costing : Total 05 Question. One from Contract terminology. Rest were easy in nature. Gupta and Gupta will suffice. 


As of now I am terminating the post here itself but will enhance it further in coming one or two days by including the analysis of Objective paper of 2014 and 2015.
