What is Water Cement Ratio? – Guide – Calculation
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 strength and durability of concrete. … Read more
Physical Properties of Cement to surprise you
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 of cement are that makes … Read more
Workability of Concrete – Definition – Factors affecting
The word “workability” defines an amalgam and composite of four concrete flow-making physical properties like mixability, transportability, mouldability, and compatibility.
Advantages of Air-Entrained Concrete
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 act as capillaries for the … Read more
What is Bogues Compounds in Cement and their Significance or Uses
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
Soundness Test of Cement by Le-Chatelier Apparatus (BONUS TIPS)
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
Erosion Control by Concrete Blocks (Fast, Cheap and Sustainable)
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 conditions. These concrete blocks are … 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
