Natural pozzolans affect several concrete properties in both fresh and hardened state. It improves the workability of concrete and increases its setting time. The reduction of concrete bleeding and

Aerated concrete is made by introducing air or gas into a slurry composed of Portland cement or lime and finely crushed siliceous filler so that when the mix sets and hardens, a uniformly cellular

Adverse effects due to improper application : Admixtures are used extensively to produce high workable, high strength high performance and highly durable concrete with minimum cost. However, these

There are several advantages of high performance concrete (HPC) application in building construction which are not achievable using conventional concrete. The strength, durability, resistance to ch

Types of Advance Cast-in-Place Concrete for Structure Repair Cast-In-Place Fiber-Reinforced Concrete When metallic or polymeric fibers (made up of steel, glass or synthetic and natural plastics) ar

Durable concrete construction requires selection of durable construction materials. Selection and properties of these construction materials are discussed.

Freezing reduces strength of concrete by 20 to 40 % when fresh concrete is subjected to freezing. Antifreeze admixtures of concrete, its properties and uses in cold weather concreting are discussed

Alkali-activated concrete (AAC) is defined as a class of cement-free concrete that is an alternative to Portland cement concrete (PCC). In AAC, the cement is entirely replaced by an alternative bin
