Concrete Compressive Toughness and Flexural toughness, what is the difference?

When it comes to estimating and testing the strength of materials, people sometimes gets confused between toughness and strength so here is answer to the difference between compressive toughness and flexural toughness.Before understanding the compression and tension \”term\” you \”must\” know what is toughness and strength.First, I would like to clarify that toughness is different … Read more

What is Ultra High Performance Steel Fiber Reinforced Concrete (UHPFRC)?

Ultra-high performance Fiber Reinforced Concrete is a relatively new construction material having minimum coarse aggregate (usually size greater than 6-7 mm is not used) having discrete random steel fibers uniformly distributed across the concrete matrix with the basic strength of above 14,000 psi (100 MPa) in 3 or 4 days that can go upto as … Read more

Strain Hardening Can Reduce The Ductility Of Steel Reinforcement

In a stress-strain curve there are various regions and limits like you might have heard about elastic limit and yielding point etc. However in this post we will not talk about all of these points and will only discuss about a phenomenon named “Strain Hardening”. This topic is very important for civil engineers and structural … Read more
