Aggregates Abrasion test – Los Angeles test
Testing of aggregates with respect to its resistance to wear is an important test for aggregates. Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing,
Concrete Technology
Concrete is the backbone of modern world. It is of utmost importance for any civil engineer to have a good understanding of the properties of concrete and its design methods.
Reinforcement – Is it needed in concrete ?
As I have already mentioned concrete is good in compression and is bad in tension. So it is very much required there should be something which will resist the tensile
What are the different tests of aggregate ?
Aggregate are the important part of concrete. Aggregates contribute to a majority of proportion (70- 80 %) in concrete and thus responsible for the increase in weight of concrete. They
What are the different quality test of concrete ?
There are different methods through which we can ensure the concrete properties. It is very important to know what all are the different quality test available for concrete , for
Ultrasonic pulse velocity (UPV) test for hardened concrete ?
We use ultra sonic pulse test (UPV) to check the quality of concrete. Concrete construction is generally gives trouble free service throughout its intended design life. However, we require these
Rebound hammer test for Hardened concrete?
We use rebound hammer to calculate the compressive strength of concrete. Concrete construction is generally gives trouble free service throughout its intended design life. However, we require these test ,
What is NDT and what are the different NDT methods available ?
Non destructive testing (NDT) methods are in use for about four decades. We perform this test on the hardened concrete surface. It is very simple to perform but still it
How carbonation test is done for a concrete structure ?
Carbonation of concrete is a process by which Carbon di Oxide from the air penetrates into the concrete and reacts with calcium hydro-oxide to form calcium carbonates. Conversion of Ca(OH)2
What are the different test available for Hardened concrete ?
Hardened concrete as the name implies it has aquired its shape and completes the initial set time period, and it is not plastic anymore. It will not be workable ,
How we can measure the workability of concrete on site ?
Workability of concrete is defined as the ease with which concrete can be handled efficiently. It is regulated by the percentage of water used for the concrete mix. a workable
