SSC JE Analysis

 Hello All,

We are aware that lot of our friend are searching for the previous year cut-off of Junior Engineer exam conducted by Staff Selection Commission.

We analysed the results of last three year SSC JE exams and we uploading them in form of tables.

It can be easily verified that number of marks are increasing both for Paper I and Paper II.

No of student appearing in Paper I and also No of student qualified for Paper II are also increasing. But in addition to it we also have to look on increasing number of Post in various departments.

As difficulty level of various year paper varies a lot, so it is hard to predict the cut-off of this year JE paper.

The marks of the candidate in various departments are also presented in form of tables which may be used a reference by aspirants hoping to be selected in various departments. 

Feel free to ask anything.

We would love to help you!!!!

GATE IN CIVIL ENGINEERING 

 

About Gate

The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) jointly administer the conduct of GATE. The operations related to GATE in each of the 8 zones are managed by a zonal GATE Office at the IITs or IISc. The Organizing Institute (OI) is responsible for the end-to-end process and coordination amongst the administering Institutes. The Organizing Institute for GATE 2015 is IIT Kanpur.

Financial Assistance

 A valid GATE score is essential for obtaining financial assistance during Master’s programs and direct Doctoral programs in Engineering/Technology/Architecture, and Doctoral programs in relevant branches of Science in Institutes supported by the MHRD or other Government agencies. As per the directives of the MHRD, the following procedure is to be adopted for admission to the post-graduate programs (Master’s and Doctoral) with MHRD scholarship/assistantship. Depending upon the norms adopted by a specific institute or department of the Institute, a candidate may be admitted directly into a course based on his/her performance in GATE only or based on his/her performance in GATE and an admission test / interview conducted by the department to which he/she has applied and/or the candidate’s academic record. If the candidate is to be selected through test/interview for post-graduate programs, the minimum of 70% weightage will be given to the performance in GATE and the remaining 30% weightage will be given to the candidate’s performance in test/interview and/or academic record, as per MHRD guidelines. The admitting institutes could however prescribe a minimum passing percentage of marks in the test/interview. Some colleges/institutes specify GATE qualification as the mandatory requirement even for admission without MHRD scholarship/assistantship.
 To avail the financial assistance (scholarship), the candidate must first secure admission to a program in these Institutes, by a procedure that could vary from institute to institute. Qualification in GATE is also a minimum requirement to apply for various fellowships awarded by many Government organizations. Candidates are advised to seek complete details of admission procedures and availability of MHRD scholarship/assistantship from the concerned admitting institution. The criteria for postgraduate admission with scholarship/assistantship could be different for different institutions. The management of the post-graduate scholarship/assistantship is also the responsibility of the admitting institution. Similarly, reservation of seats under different categories is as per the policies and norms prevailing at the admitting institution and Government of India rules. GATE offices will not entertain any enquiry about admission, reservation of seats or award of scholarship/assistantship.

Employment

Several public sector undertakings (PSUs) have, in the past, used GATE scores for screening for providing a salaried employment. A select few such organizations are: Bhabha Atomic Research Centre, Bharat Heavy Electricals Limited, Indian Oil Corporation Limited, National Thermal Power Corporation, Power Grid India, etc. It is expected that such PSUs would use GATE Scores this year as well.

Hot Weather Concrete Construction

 When the temperature of freshly mixed concrete approaches approximately 77 degrees Fahrenheit adverse site conditions can impact the quality of concrete. Ambient temperatures above 90 degrees Fahrenheit and the lack of a protected environment for concrete placement and finishing (enclosed building) can contribute to difficulty in producing quality concrete.

 The precautions required to ensure a quality end product will vary depending on the actual conditions during concrete placement and the specific application for which the concrete will be used. In general, if the temperature at the time of concrete placement will exceed 77 degrees Fahrenheit a plan should be developed to negate the effects of high temperatures.

 The effect of high ambient temperatures and high temperature concrete component materials have on the setting time of concrete mixtures is a topic of concern due to the reduced time in which concrete must be placed, consolidated and finished; increased potential for plastic shrinkage cracking, thermal cracking and cold joints; potential strength reduction due to high water demand and high curing temperatures; difficulty in controlling air content; and increased urgency for applying appropriate curing method at an early age.

 As a general rule of thumb an increase of 20 degrees Fahrenheit will reduce the setting time of a concrete mixture by as much as 50 percent. As an example, a concrete mixture that reaches final set in three hours at 60 degrees Fahrenheit may reach final set in as little 1½ hours at 80 degrees Fahrenheit. As the concrete temperature increases the setting time is further reduced. The actual temperature of the concrete mixture as delivered is effected by the temperature of the materials used in the mixture, the cementitious content of the mixture, the temperature of the equipment used to batch and transport the concrete, and the ambient temperature and conditions at the project site. Concrete applications may be considered hot weather concrete at temperatures ranging from 77 to 95 degrees Fahrenheit depending on the specific application. Precautions should be planned in advance to counter the effects of high temperature well in advance of execution to counter these effects.

 Precautions may include use of materials with a good performance history in high temperature conditions, cool concrete materials or concrete mixture, provide concrete consistency and placement equipment and crew for rapid placement, reduce time of transport, schedule placement to limit exposure to atmospheric conditions (night time placement or more favorable weather), plan to limit rapid moisture loss (sun screens, wind screens, misting, or fogging), and consider the use of an evaporation retarder. Schedule a preconstruction meeting including all of the participants to discuss the plan to control the effects specific to the project and expected conditions. 

 The precautions may include some or all of the following:

•  Moisten subgrade, steel reinforcement, and form work prior to concrete placement.
•  Erect temporary wind breaks to limit wind velocities and sunshades to reduce concrete surface temperatures.
•  Cool aggregates and mixing water added to the concrete mixture to reduce its initial temperature. The effect of hot cement on concrete temperature is only minimal. 
• Use a concrete consistency that allows rapid placement and consolidation.
•  Protect the concrete surface during placement with plastic sheeting or evaporation retarders to maintain the initial moisture in the concrete mixture.
•  Provide sufficient labor to minimize the time required to place and finish the concrete, as hot weather conditions substantially shorted the times to initial and final set.
•  Consider fogging the area above the concrete placement to raise the relative humidity and satisfy moisture demand of the ambient air.
•  Provide appropriate curing methods as soon as possible after the concrete finishing processes have been completed.
•  In extreme conditions consider adjusting the time of concrete placement to take advantage of cooler temperatures, such as early morning or night time placement.
•  The use of liquid nitrogen is one option to reduce concrete’s temperature during hot-weather concreting.
•  Modify concrete mix designs as appropriate. Retarders, moderate heat of hydration cement, pozzolanic materials, slag, or other proven local solutions may be used. Reduce the cement content of the mixture as much as possible, while ensuring the concrete strength will be attained
• Limit the addition of water at the job site.

Cold Weather concreting

1.  WHAT is Cold Weather? 

 Cold weather is defined as a period when the average daily temperature falls below 40°F [4°C] for more than three successive days. These conditions warrant special precautions when placing, finishing, curing and protecting concrete against the effects of cold weather. Since weather conditions can change rapidly in the winter months, good concrete practices and proper planning are critical.

2. Why Consider Cold Weather?

 In its plastic state, concrete will freeze if its temperature falls below about 25°F [-4°C]. If plastic concrete freezes, its potential strength can be reduced by more than 50% and its durability will be adversely affected. Concrete should be protected from freezing until it attains a minimum compressive strength of 500 psi [3.5 MPa], which is about two days after placement for most concrete maintained at 50°F [10°C]. Low concrete temperature has a major effect on the rate of cement hydration, which results in slower setting and rate of strength gain. A good rule of thumb is that a drop in concrete temperature by 20°F [10°C] will approximately double the setting time. The slower rate of setting and strength gain should be accounted for when scheduling construction operations, such as form removal.Cement hydration is a chemical reaction that generates heat. Newly placed concrete should be adequately insulated to retain this heat and thereby maintain favorable curing temperatures. Large temperature differences between the surface and the interior of the concrete mass should be prevented as cracking may result when this difference exceeds about 35°F [20°C]. Insulation or protective measures should be gradually removed to avoid thermal shock .

 3. How to place concrete in cold weather?

1. The ready mixed concrete producer can control concrete temperature by heating the mixing water and/or the aggregates 
2. Placing concrete in cold weather provides the opportunity for better quality, as cooler initial concrete temperature will typically result in higher ultimate strength. 
3. Slower setting time and strength gain of concrete during cold weather typically delays finishing operations and form removal.
4.  Chemical admixtures and other modifications to the concrete mixture can accelerate the rate of setting and strength gain. Calcium chloride is a common and effective accelerating admixture, but should not exceed a maximum dosage of 2% by weight of cement.
5.  Accelerating the rate of set and strength gain can also be accomplished by increasing the amount of portland cement or by using a Type III cement (high early strength).
6. The relative percentage of fly ash or ground slag in the cementitious material component may be reduced in cold weather but this may not be possible if the mixture has been specifically designed for durability.
7. Concrete should be placed at the lowest practical slump as this reduces bleeding and setting time.
8. Adequate preparations should be made prior to concrete placement. Snow, ice and frost should be removed and the temperature of surfaces and metallic embedments in contact with concrete should be above freezing. This might require insulating or heating subgrades and contact surfaces prior to placement.
9.  Materials and equipment should be in place to protect concrete, both during and after placement, from early age freezing and to retain the heat generated by cement hydration. Insulated blankets and tarps, as well as straw covered with plastic sheets, are commonly used measures.
10.  The concrete surface should not be allowed to dry out while it is plastic as this causes plastic shrinkage cracks.Subsequently, concrete should be adequately cured. Water curing is not recommended when freezing temperatures are imminent. Use membrane-forming curing compounds or impervious paper and plastic sheets for concrete slabs.

•  Cold Weather Concreting Guidelines 

1.  Use air-entrained concrete when exposure to moisture and freezing and thawing conditions are expected.
2.  Keep surfaces in contact with concrete free of ice and snow and at a temperature above freezing prior to placement.
3.  Place and maintain concrete at the recommended temperature.
4.  Place concrete at the lowest practical slump.
5.  Protect plastic concrete from freezing or drying
6.  Protect concrete from early-age freezing and thawing cycles until it has attained adequate strength.
7.  Limit rapid temperature changes when protective measures are removed

 

 Doubt Point

1. A 10m thick bed of sand is underlain by a layer of clay 6m thick. The water table that was originally at ground level is lowered by drainage to a depth of 4m, whereupon the degree of saturation above lowered water reduces to 20%.

Determine the increase in effective pressure at mid of clay layer due to water table lowering. Given saturated densities of sand and clay as 2.1g/cc and 1.8g/cc and the dry density of sand 1.7g/cc.
