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.
Water is an important ingredient of a concrete mix and water cement ratio is an important factor in concrete or cement mix design. While working at site, concrete workers always try to add water in it so as to increase the workability of concrete but actually they are reducing the…continue reading →
Do you know cement concrete is the world’s most consumed man-made construction material? Yes! After water it’s the most consumed material on the universe and all is just because of the unique physical properties of cement. So without wasting our time lets jump straight to know what the physical properties…continue reading →
The word “workability” defines an amalgam and composite of four concrete flow-making physical properties like mixability, transportability, mouldability, and compatibility.
There are multitude advantages of air-entrained concrete, it not only enhances the durability of the fresh concrete but also render resilience of hardened concrete. We all know that concrete, though from appearance looks solid and firm, but it actually has many pores and voids in it. These voids and pores…continue reading →
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 →
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…continue reading →
Gone are the days when a water canal projects are delayed by a time taking rip rap erosion control works.Why?Yes, because now the erosion control by concrete blocks is a fast and easy solution. These blocks can be used in projects involving light to moderate water wave and open-channel flow…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 →
