Fineness of cement is another quality control parameter that experts keep in check of at the laboratory. The size of the particles of OPC impact the surface area and the heat of hydration. I’ve already explained the definition in my previous article on different physical properties of cement. So, if…continue reading →
We intentionally entrain microscopic air bubbles in concrete to enhance its durability against freeze and thaw. Air entraining agent or pore-forming agents are admixtures that are used to incorporate air into the concrete mix. They enhance the workability of concrete and improve resistance against salt scaling or freeze and thawing.…continue reading →
So, you’re one of the future constructors and are wondering what is concrete definition in civil engineering. Well, in simple terms, concrete is a composite material or a mixture of fine and coarse aggregate that is bonded together by cement paste. The aggregate – both fine and coarse, are termed…continue reading →
Development length is extended length of reinforcement across the two adjoining sections or elements of structures whereas lap length is to extend rebars.
Bogues compounds are responsible for initial setting of the cement grout. These compounds have been researched extensively by an American chemist named Rober Herman Bogue (R.H. Bogue) who is well known for his books on The Chemistry of Portland Cement and the Chemistry and Technology of Gelatin and Glue. After…continue reading →
Hempcrete Blocks are basically made with the help of two ingredients i.e. lime as binding agent or binder mixed with the core of hemp plant. After decades of modernization, advancement and innovation in science and particularly in construction engineering, the humans have realized that they had moved far away from…continue reading →
Soundness test of cement by Le-Chatelier apparatus is very easy but very important test along with many other quality tests on cement. Before going to the exact details, procedure and calculations of soundness test of cement by Le-Chatelier apparatus, let’s first discuss about the overview of soundness. As an engineer…continue reading →
The word hardened concrete means the concrete which has been initially set and is not fresh like a workable and plastic concrete. So we can say that the word hardened concrete specifies its stage of "plasticity" which is gone and now the concrete is in hardened form after setting. The…continue reading →
