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.
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 give body of the 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 both fresh and hard 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 test , because of structural …
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 , because of structural deficiency, material …
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 lacks in implementation because its …
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 into CaCO3 by action of …
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 , i.e. it will not possible …
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 concrete should be able to …
Cement is the gem ingredient of a concrete mix, it is a binder which sets, hardens and creates a bond between the other materials in concrete and helps to bind them together within its setting …
Concrete as mentioned in the previous posts it is the most widely used construction material by the construction industry. It is to be noted that concrete is a material which when poured acquires the shape …
