Have you ever wondered how civil engineers use concrete retarders to compensate the accelerating effect of high temperature in mass concrete? Or why thy add sugar in concrete while pouring? The use of concrete retarders as admixture slows down the setting rate of concrete. Slow initial setting time allows site engineers to place concrete in … Read more
Asphalt concrete also known by the name of blacktop or flexible asphalt which is generally made by mixing different materials like coarse aggregate, fine aggregate, filler and the binding material. It is a stabilized granular soil that acts as a durable water and abrasion-resistant structure. It comprises of sand or well-graded aggregate mixed with 3 … Read more

Rutting in flexible pavement is creation of a depression or a groove. It is typically shown as wheel path engraved on the road surface. The main cause of rutting failure is the deformation of the asphalt concrete under the loading from vehicles. In cold climate areas, rutting happens as snow studded tires travel in a … Read more
If you’re bit concerned about quality of freshly mixed concrete, you’d be dealing with terms like slump of concrete, consistency, fineness of cement, and compressive strength. Of all, slump of concrete is an important quality control parameter. The next time you step in as incharge of concrete pouring activity, you should know different types of … Read more
You might have heard about concrete curing, a process of spraying water on freshly placed concrete. But probably have not heard about other methods of curing of concrete like using water-soaked hessian cloth or ponding. But do you know why concrete needs curing? Why curing is so important for the longevity and durability of concrete? … Read more
Air permeability test or Blaine’s air permeability method is one of the most accurate methods of finding the fineness of the cement. In this method, we determine fineness of the cement with the help of an apparatus patented by LEA and NURSE, it is done by the NURSE and BLAINE’S method as, apparatus consists of … Read more
