How to prepare for GATE ?

               GATE preparing can be easy as preparing for your University Exams. The main thing is you should start early with a quality books [i mean with good subject] and guidance. The main thing is you must remember that GATE paper focus on your in depth knowledge of subject, your basics, presence of mind during examination etc.


Following are the recommendations while preparing for your GATE exams:


              The questions are generally derivations of the fundamentals. First get your fundamentals right, and then test yourself on those fundamentals. When you have done this, you should pit yourself with the competition, which means a mock test which would give you a percentile to let you know where you stand amongst competitors. How do you choose which coaching material to go with. This is something that is quite subjective. A coaching material cannot be assessed until you have gone through it. So, you could go by the word of your seniors[i mean both senior students and your Professors too] as to what coaching material they followed to prepare for GATE. Here are some parameters on which you can decide whether you should go for a particular coaching institute, use a particular coaching material, or tests:


1. Material Collection

• Syllabus: First collect the syllabus from official site. CLICK HERE to view the syllabus.

• Divide the books in two groups - Fundamental and basic concepts  &   Problem oriented

• Some good guide books for GATE

• Previous questions papers 

2. Keep contact with some expert and GATE experienced persons

3. Start from the basics:

• Refer at least 5 books, it will widen your knowledge.
• Note down the probable concepts (definitions, unit, dimension etc.)
• Note down necessary theories, formulae etc
• Solve problems as maximum as possible (from text books, Guide books etc)
• Think about various tricks in solving problems(if necessary, note it)
• Go for series of self tests based on this chapter(take other’s help to conduct tests)
• Continue the self tests until getting a very good score

4. Solve more and more problems, discover more and more new tricks… Most probably senior faculty helps in this point of view.

5. Follow the same procedure for the rest chapters

6. Finally, go for self tests based on whole syllabus (take other’s help to conduct these tests)

WHEN SHOULD I START PREPARATION FOR GATE?

              Seniors recommend to start your GATE preparations right from the second year of your engineering. Buy good books and study materials for GATE. Collect previous Question Papers, Mock test papers and solve them. This not only helps to excel in your University Exams, but also help you to grasp fast and digesting the concepts. The main thing you should revise always else, every effort become worthless with out revising and self check.

 

HOW GATE IS HELPFUL FOR RESEARCH?

           Admission to post graduate programmes with MHRD and some other government scholarship/assistantship at engineering colleges/institutes in the country are open to those who qualify through GATE. GATE qualified candidates with Bachelor degree in Engineering/ Technology/ Architecture/ Pharmacy or Master degree in any branch of Science/Mathematics/Statistics/Computer Applications are eligible for Master/Doctoral programmes in Engineering/ Technology/Architecture/Pharmacy as well as for Doctoral programmes in relevant branches of Science. Some institutions specify GATE as the mandatory qualification even for admission of self-financing students to postgraduate programmes. GATE qualified candidates in Engineering disciplines are also eligible for the award of Junior Research Fellowship in CSIR Laboratories. Some government organizations prescribe GATE qualification as a requirement for applying to the post of a Scientist/Engineer.

Types of Admixtures for Concrete

Admixtures

 

                   Admixtures are ingredients other than aggregates, water, fibers, and hydraulic cement that are added to the concrete batch immediately before or during mixing. A proper use of admixtures offers some particular  beneficial effects to concrete, improved quality, acceleration or retardation of setting time, increases  frost and sulfate resistance, control of strength development, and improved workability.
 

Calcium chloride (CaCl_2)

                 Calcium chloride is generally used in cold weather to accelerate the setting time and produces an early finish of the concrete. CaCl_2 can effect the characteristics of concrete causing corrosion of unprotected reinforcement, in a decrease the resistance to freeze,  increased internal stresses, an increase in the attack of sulfates, temperature rise, and an increase in the amount of drying shrinkage between 10 - 50 %.

Set Retarding Agents

                These agents are primarily used for delaying the setting time of concrete. Set retards are useful, but are not the solution to poorly designed mixes. These retarders must be uniformly dispersed throughout the whole mix [mortar] . Failure to do so will result in the admixture remaining in voids and causing some areas to remain plastic. This leads to plastic shrinkage.

Water Reducing Agents

                A certain amount of the water is added to concrete to make the concrete place able and to ignite the hydration reaction of Portland cement. Over 50% of the water have no useful effect and have direct results in durability, the strength of concrete and drying shrinkage. These water reducing agents added to the concrete reduce the water demands of the mix, increase the strength, to reduce the cost, maintain the workability, reduce segregation, reduce honeycombing, reduce cracking, reduce bleeding,  and permeability, increase bond strength of concrete to steel, and reduce drying shrinkage. An average of 12 to 15 % reduction in the total water content will accomplish this goal.

Accelerating Agents

                These Accelerating agents are used to shorten the setting time and increase the early strength of the concrete. These agents are mainly used for concrete needing to be used immediately in some special cases like the marine constructions etc.

Air Entraining Agents

These Air entraining agents are used primarily to increase the resistance of freezing and thawing. They also produce

•     lower water demands for a particular slump,

•     high  resistance to deicing chemicals,

•     to improve workability,

•     reduce segregation and bleeding,

•     increase durability, and improve pump ability and

•     reduce the amount of fine aggregate needs in the mixture.

Even though air entrainments have no effect on drying shrinkage, they create a slight deficit in the concrete strength.

Technozion - NIT Warangal

                          Technozion is back with more than a bang. With Technozion X bringing home the X factor, They bring to you the X and more! With this year’s theme centering on technology and evolution, they have brought to the table quite a few changes with more events and guest lectures than ever before. Online events and spotlight events, workshops for those who want to learn, and for those who want to share their knowledge. Three days lined up with Robotics and many more events ready to set Warangal sizzling in the cool autumn.


 Special Focus on CIVIL ENGINEERING events:

• CONCRETE CANOE 

                         A concrete canoe is a canoe made of concrete, typically created for an engineering competition.In spirit, the event is similar to that of a cardboard boat race—make the seemingly unfloatable float. However, since concrete and other poured surfaces are an integral part of a civil engineer's education, concrete canoes typically feature more development than cardboard boats.

Science behind the Concrete Canoe:
                                               
Principle:

                         Ignoring hydrodynamic effects, all ships or boats float because the weight of the water they displace is equal to the weight of the boat (Archimedes' principle). However, many boats are made of materials that are denser than water, meaning that the boat will sink if filled with water. Although it is not required by the rules of the competition, some competitive concrete canoes have concrete mix designs that are less dense than water. They must pass a test in which the canoe is filled with water and pushed below the surface; the canoe must then resurface in order to qualify for racing. This is possible because, unlike normal concrete which uses sand and small rocks, concrete canoes are created with porous aggregates such as Macrolite and microspheres. However, because many teams still design their concrete mixes to be denser than water, in the United States, teams are allowed to insert concrete-covered, non-structural foam pieces in their canoes to make the canoes float after being submerged.

• TENSIGRITY

                          He who is afraid to experiment will never see the path of progress . A bold experiment which has grown into a hotspot for civil engineers and almost anyone who has ever admired the beauty of any structure . This innovative event requires participants to build structures with multiple struts or beams which do not touch each other and are supported just by strings !
