Concrete Aggregates From Discarded Tyre Rubber
The scarcity and availability at reasonable rates of sand and aggregate are now giving anxiety to the construction industry. Over years, deforestation and extraction of natural aggregates from river beds, lakes and other water bodies have resulted in huge environmental problems. Erosion of the existing topography usually results in flooding and landslides. Moreover, the filtration of rain water achieved by deposits of natural sand is being lost, thereby causing contamination of water reserves used for human consumption. Hence, to prevent pollution authorities are imposing more and more stringent restrictions on the extraction of natural aggregates and its crushing. The best way to overcome this problem is to find alternate aggregates for construction in place of conventional natural aggregates. Rubber aggregates from discarded tyre rubber in sizes 20-10 mm, 10-4.75 mm and 4.75 mm down can be partially replaced natural aggregates in cement concrete construction.
About one crore 10 lakhs all types of new vehicles are added each year to the Indian roads. The increase of about three crores discarded tyres each year pose a potential threat to the environment. New tyre is made of natural rubber (also called virgin rubber), styrene-Butadien Rubber (SBR), Polybutadienc Rubber (PBR), Carbon black, Nylon tyre cord, rubber chemicals, steel tyre card and Butyl rubber.

GATE PREPARATION
As GATE exam is just a month around, most of the students started heating up for GATE exam. This is the time when students are done with their regular engineering exams and it’s time to get really serious about GATE. If someone misses this month or doesn’t get serious with preparation then cracking GATE would just be a nightmare.
With a short time to prepare for GATE, that consists of four years of engineering courses, it can be a really a confusing task. Even students preparing yearlong could be puzzled about their approach for preparing for GATE. In this post I tried to give my approach toward competitive exams specially at the verge of the exam.
I know most of the students think that saying it is easier than doing it. But remember that to be successful, doing and trying hard is more important than just keeping on thinking. With this post I call all of you to leave your beds for a month. Exhaust yourselves, work hard and stay focused for GATE. Believe me you will make it happen or at least you will feel great that you gave a sincere try.
If you want to do great in GATE then there are five essential things you need to follow at this moment.
- Easy subjects first
When time is less for preparation, the best thing do is to start preparing with the subjects you feel easy about. If you analyze deeply, most of the subjects have almost the same weight age.
Easy subjects will finish quickly and make you more confident. As soon as you finish a topic you will see more energy and excitement of cracking the GATE. - Use Short notes
Try to collect short notes, such as brilliant tutorials, GATE forums or some other study material. This will help you speed up your preparation, as the notes don’t go into every detail of the subject, cover the essential concepts needed for the exam and save time.
Do follow only one note as different notes may use different analogy and may lead to confusion. - Get Question banks
Have a question bank or GATE questions’ answer book for sure. As soon as you finish a topic you can refer to different types of questions that can be asked. Don’t worry if you cannot solve all the questions. At least you will get an idea of the type of question you can expect and where do you stand. - Previous year papers
Every GATE aspirant must solve previous year question papers. First and foremost it gives an idea about the GATE question paper. Secondly, sometimes you may get some questions from previous papers. - Avoid reading from soft copies
It’s very common among student to search and download the soft copies of the books and notes. These soft copies can be easily found, downloaded and shared. But the disadvantage with soft copies is that you will read them on computer and can be easily distracted to other things like music, videos, internet … etc.
It is always beneficial to make a hard copy of the important pages and avoid computer to concentrate well on the desired subject. You can also write down some important points if don’t want to have printed copy.
The idea is to avoid all kind of distraction that prevents GATE preparation.
I would strongly recommend you to avoid all time wasters till the GATE exam. Time wasters can be TV, Movies, Music, Excessive Internet, Friends, and any other thing that consume your time without being beneficial for GATE preparations.
Best Of Luck

Top marks for years would give you an idea of how much effort is needed to stand on top in the competition to get reach to your dream destinations. It’s a good evaluating point for your preparation and a good check point for your desired targets.
To help you with that i give out the GATE 2012 top mark
