There are many methods through which high-strength concrete can be produced. Some of the widely known methods and techniques are- re-vibration, the use of admixtures, high-speed slurry mixing, prevention of cracks, Sulphur impregnation or Sulphur filling, use of cementitious aggregates, ...
Mechanism of High-Performance Concrete
High-performance concrete can be produced through the use of low w/c ratio, pozzolanic materials, packing aggregates densely, and improve transition zone strength. Superplasticizers reduce water content by dispersing cement particles and maintain the required workability. Concerning pozzolanic materials, it improves ...
Ultra-high-Performance Concrete: Characteristics, and Applications
Ultra-high-performance concrete (UHPC) is defined as ‘concrete that has a minimum specified compressive strength of 150 MPa with specified durability tensile ductility and toughness requirements; fibers are generally included to achieve specified requirements”, as per ACI 239R-18. Commonly, the UHPC ...
What are the Differences Between High-Strength and High-Performance Concrete?
High-strength concrete and high-performance concrete are not synonymous because strength and performance of concrete are different properties of concrete. High-strength concrete is defined based on its compressive strength at a given age whereas high-performance concrete is defined based on performance ...
High-Performance Concrete: Composition, and Features
High-performance concrete (HPC) is produced by careful selection and proportioning of its constituents namely cement, sand, gravel, cementitious materials such as fly ash; silica fume; and slag, and chemical admixtures for instance high range water reducing admixtures. The strength and ...
20 Advantages of High Performance Concrete in Design and Construction
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 chemical attack, and workability of high performance concrete are high. So, high performance concrete is ...
