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,...

Our world is experiencing changes which are having a significant effect on our environment. Technology is getting better and better and building construction is no exception. Buildings today we see are vastly...

What Is Hollow Core Slab? Hollow core slabs also know as "voided slabs" or "concrete planks" are prestressed precast concrete slabs panels having usually circular openings and are typically used in construction...

Compaction is the process of removing air voids of soil in order it increase its dry unit weight. Mechanical effort is required in order to compact soils due to which rollers...

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...

Development length and Lap length Many students get confused between Development length and lap length terminologies.  Lap length addresses the length of the bar needed to transfer the stresses to the other...
