This video (at the end) explains the production of a prestressed concrete unit (Double T) on a prestressing concrete plant. Double T is a versatile prestressing unit which are mostly used in parking...

Objective Slump test is used to measure the consistency of concrete mix. Indirectly it is used to check whether workability of concrete mix is up to desired level or not. Equipment Used Slump Cone Tamping Rod Spatula Brush Procedure Cone...

Taiwan was hit by a strong 6.4 magnitude on Saturday 10th Feberuary 2016. It is estimated that this tragic accident caused almost 116 deaths according to Taiwan's Central News Agency reported. Weiguan...

Introduction Fiber reinforced polymer (FRP) composite systems, consist of fibers embedded in a polymeric matrix. They are used for Flexural and Shear strengthening of reinforced concrete (RC) members. Since the late 1980s,...
hydration of portland cement

Introduction Hydration Of Portland cement is defined as "dissolution-precipitation" process. During this process cement in mix reacts with water and transforms from fluid phase to porous solid matter known as concrete. This process...

As Civil Engineers, We all know that microstructure of concrete is very important in terms of strength durability and serviceability. Many deleterious actions operate through microstructure of concrete therefore, it is...

Every substance in concrete having average particle size less than 125 microns in known as "powder". If we examine finely grounded powder when it comes in contact with water, we will see...

Introduction Concrete Strength testing is always a requirement in the field of concrete construction. Usually, when concrete batch arrives, two or three cylinders or cubes are cast so that quality control is...

Civil engineering has come a long way since its evolution. Starting from the simple structures to the skyscrapers today, the world has witnessed immense advancement in the engineering knowledge. It has...

Durability Durability of concrete can be defined as its ability to resist weathering action, chemical attack, abrasion or other process of deterioration and hence retains its original shape, dimension, quality and serviceability. Deleterious...

What Is Segregation? Segregation refers to separation of different concrete phases. It happens when concrete mix is not cohesive enough. Slump Test in Conventional concrete and Flow test in Self Compacting Concrete can...

Definition ACI 237 defines Self Compacting Concrete (SCC) as "highly flowable, non-segregating concrete that can spread into place, fill the formwork, encapsulate the reinforcement without any mechanical consolidation. Idea Of Self Compacting Concrete SCC...

Foam Concrete Foam concrete also known as light weight concrete, low density concrete is special type of concrete having low density varies from 400 kg/m3 to 1000 kg/m3. The density is usually...
bendable concrete

Bendable Concrete? What? How is it even possible? We all know that concrete is a brittle material poor in tension so how can it bend? ConFlexPave answers the questions! Nanyang Technological University...

  Spalling Spalling is considered as one of the most complex and poorly understood phenomenon occurred at high temperatures. (Khoury 2000; Tenchev and Purnell 2005) Mostly it is assumed that this phenomenon occur...

Diamond was known to be the hardest material found on planet earth but not any more. A group of scientists have discovered a new form of carbon which they say is...
