Compaction factor test for workability of concrete

Compaction Factor Test

The compaction factor test is done to check the workability of concrete, on the basis of weight ratio between partially compacted to fully compacted concrete. We can’t use the slump test for low workable concretes. Concretes we mostly use in mass dam structures or road pavements have significantly low values of slump. For all such … Read more

What is concrete grinding? How to do it? 

What is concrete grinding?

Whether you prefer to go for exposed concrete floors or you have recently bought a precast concrete countertop, you would be annoyed and worried by the roughness in the concrete finish. The only thing you can do about it is; concrete grinding and polishing. Besides removing imperfections and roughness of the concrete surface, there are … Read more

Fineness of Cement – Definition – Test

Fineness of cement

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 would reproduce my answer to … Read more

Air entraining agents – Definition – 5 Types

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. Definition In normal concrete, the … Read more

Concrete Definition – 3 Basic Components – Grades

Concrete definition

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 as filler content while the … Read more

Bogues Compounds in Cement and their Significance or Uses

Different Bogue's Compounds in Cement Details

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 his extensive research, Bogue has … Read more

Hempcrete Blocks – light weight REPLACEMENT of Concrete

Hempcrete Blocks an innovative replacement of Concrete

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 nature resulting in so many … Read more

Soundness Test of Cement by Le-Chatelier Apparatus (BONUS TIPS)

Apparatus for Soundness of Cement by Le-Chatelier

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. A sound cement doesn’t undergo volumetric changes i.e. … Read more

Properties of Hardened Concrete

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. [su_note]Workability and related properties of fresh concrete are … Read more
