Concrete technology

Concrete is the second most consumed material in the world, after water.  It is fundamentally playing a huge part in shaping our world. With its extensive use, there is a growing need to prioritize and ensure the quality of concrete. The quality of concrete depends upon various factors such as the quality and quantity of […]

The slump cone test is the most commonly used method to determine the workability of the fresh concrete mix. Before we get further into the test procedure, one should have sufficient knowledge about the term workability, so let’s take a short look at the term workability. What is the workability of concrete? In layman’s terms,

What is spalling of concrete? Spalling of concrete refers to the deterioration of the surface of concrete, resulting in flaking and peeling off the surface layer of concrete. It occurs in various structures such as buildings, bridge decks, multistorey frames, water tanks, etc. Various factors such as environmental conditions, depth of concrete cover, and reinforcement

What is a concrete curing compound? Concrete curing compounds are nothing but chemical mixtures that are used to reduce the loss of moisture content from the concrete during the early stages of setting and hardening. They are not only used for curing fresh concrete but also used for curing concrete after the removal of formwork.

The compressive strength test is the most common destructive test conducted on the hardened concrete cube because it is easy to perform and most of the properties of the concrete are related to its compressive strength. What is the compressive strength of concrete? The compressive strength of concrete is defined as the maximum crushing stress

What is honeycomb in concrete? Honeycomb in concrete refers to the voids or cavities present within the concrete matrix. The voids are formed due to the entrapment of air or insufficient filling of concrete during the casting process. It gets the name honeycomb because these voids resemble the shape of honeycomb cells. It is typically

Are you tired & bored of plain concrete surfaces in your outdoor spaces? If so, Let’s discover the beauty and versatility of stamped concrete! What is stamped concrete? Stamped concrete is nothing but conventional concrete that is designed or imprinted to resemble the look of other materials such as brick, flagstone, slate, wood, etc. It

What is the curing of concrete? Curing of concrete can be defined as the process of maintaining an optimum moisture content and desirable temperature for a certain period of time after concrete placement, so that the hydration process may continue until the concrete can develop sufficient strength. Why curing of concrete is important? Concrete derives

What is the Crazing of concrete? Crazing is the development of a network of fine random cracks on the surface of the concrete caused by shrinkage of the surface layer. These cracks are very fine (3 mm) and they do not penetrate much below the concrete surface. These cracks often look like a spider web

What is an Ultrasonic Pulse Velocity Test? Ultrasonic pulse velocity test is a method of assessing the quality of concrete by measuring the time of travel of an ultrasonic pulse of longitudinal vibrations, passing through the concrete to be tested. The first report of the measurement of velocity appeared in the USA in the mid-1940s.
