Concrete

Concrete remained the backbone of global infrastructure, while rising durability demands, environmental concerns, and accelerated project timelines reshaped how it was designed, specified, and used. In 2025, innovation in concrete …

Flat slabs are widely used in buildings of the 21st century as they provide open spaces, fast constructions, and easy layout planning. The system is characterized by the slab being …

What is Accelerated Concrete? Accelerated concrete is a type of concrete in which the natural process of setting, hardening, and strength development is deliberately increased to achieve results within a …

Concrete is one of the most durable construction materials, but it is not immune to deterioration. Distress in concrete structures can develop due to several factors, including environmental exposure, poor …

Delayed Ettringite Formation (DEF) is a degradation process in concrete where ettringite, a sulfate-based compound, forms after the concrete has hardened instead of during the early hydration stage. This delayed …

Concrete creep is the gradual, long-term deformation of hardened concrete under sustained load, causing an increase in strain without a change in applied stress. It occurs as a slow, continuous …

Thermal cracking in concrete occurs due to temperature differentials within a structure, leading to tensile stresses that exceed the material’s tensile strength. This issue is particularly common in mass concrete, …

Hardened concrete is the solid state of concrete that results from the curing process, during which the mixture of cement, water, and aggregates chemically reacts and sets. This transformation leads …

What is Curling? Curling is the distortion of a slab into a curved shape which is caused by the upward or downward bending of its edges. This phenomenon primarily occurs …

Quality of water to be used for construction has been classically defined in IS 456. It is  at par with the quality of drinking water for all practical purposes and …
