Sulphate attack is a chemical reaction between sulphate ions and components of concrete, leading to the deterioration of the material. It primarily affects the durability and structural integrity of concrete structures, often resulting in expansion, cracking, and loss of strength.

Sulphate Attack

A chemical reaction is a process where substances, known as reactants, are transformed into different substances, called products, through the breaking and forming of chemical bonds. This transformation involves changes in energy and is governed by the principles of conservation of mass and energy.

Durability of concrete refers to its ability to withstand weathering, chemical attack, abrasion, and other processes of deterioration over time, ensuring the structure maintains its desired properties and strength. It is crucial for the longevity and safety of concrete structures, influenced by material selection, design, and environmental conditions.

Durability Of Concrete

Structural integrity refers to the ability of a structure to withstand its intended load without experiencing failure or excessive deformation. It is a critical consideration in engineering and architecture to ensure safety, functionality, and longevity of buildings, bridges, and other constructions.

Expansion refers to the process of increasing in size, volume, quantity, or scope, and it can occur in physical, economic, or abstract contexts. Understanding expansion involves recognizing the underlying factors that drive growth and the implications it has on the surrounding environment or system.

Expansion

Cracking refers to the process of breaking down complex organic molecules into simpler molecules, often used in the petrochemical industry to convert heavy hydrocarbons into lighter, more valuable products like gasoline and olefins. It involves the breaking of carbon-carbon bonds and can be achieved through methods such as thermal cracking, catalytic cracking, and hydrocracking, each with distinct mechanisms and applications.
