Behaviour of Concrete in Extreme Fire
The behavior of concrete in extreme fire is dependent on the composition and properties of the concrete structure. The type of aggregates used, the mix design, the moisture condition, and age are the factors that govern the behavior of concrete ...
CONCRETE MIX DESIGN USING CRUSHED SAND
The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. The proportioning of ...

Ready Mix Concrete Placement Methods for Concrete Construction
The placement methods of readymix concrete plays an important role as it affects the strength and durability of concrete structures. The time of delivery, quality checks and time of placements affects the ready mix concrete. Ready mix concrete is a ...
PROPORTIONING OF HIGH STRENGTH CONCRETE
When developing mixture proportioning for high-strength concrete, three fundamental factors must be considered in order to produce a mix design satisfying its intended property requirements: Mechanical properties of the aggregates, Mechanical properties of the paste, Bond strength at the paste-aggregate ...
What is Insulating Concrete Formwork? How it is Used in Construction?
What is Insulating Concrete Formwork? Insulating concrete formwork (ICF) is a building system that uses lightweight formwork (made from an insulating material) to support concrete walls whilst they are being cast in-situ and which is then left in place as ...
