The alkali-aggregate reaction (AAR) occurs when alkalis, typically sodium and potassium ions from cement, reacts with minerals present in aggregates within concrete.This reaction can lead to the formation of a …

Segregation in concrete refers to the separation of coarse aggregates from the cement paste during the mixing and placing process. This can occur due to improper mix design, excessive water …

‘Shotcrete’ is concrete conveyed through a hose and pneumatically projected at high velocity at the projected surface, as a construction technique. It is a sprayed concrete which is batched in …

Efflorescence in concrete refers to the formation of white, powdery deposits on the surface due to salt leaching. These salts are usually present in the concrete mix or can be …

Cracks in a Reinforced Concrete (RCC) slab refer to fissures or openings that develop within the concrete structure. They can emerge for a multitude of reasons, ranging from natural factors …

Reactive Powder Concrete (RPC) is an advanced construction material that differs significantly from traditional concrete. It is characterized by its unique composition, which includes fine powders and small steel fibers …

In the ever-evolving landscape of construction, concrete stands as an unrivalled titan, shaping our modern world with unwavering strength. But beneath the surface of this seemingly invincible material lies a …

The global surge in urbanization and infrastructure development has led to a significant increase in the demand for silica fumes in the construction industry. Its unique properties have made it …

Statically indeterminate structures made of reinforced concrete like fixed ended one span beams, continuous beams and frames are designed considering internal forces like bending moment, shear force and axial thrust …

Concrete spalling is a phenomenon where the surface layers of concrete deteriorate, resulting in the detachment, flaking, or chipping of the concrete. It is characterised by the loss of concrete …
