High workability concrete - The Concrete CentreThe workability of fresh concrete should be suitable for each specific application to ensure that the operations of handling, placing and compaction can be undertaken efficiently. BS EN 206 and BS8500 the European and UK standards for concrete give guidance on workability for different uses. The handling and placing properties of concrete mixes can be improved considerably by the use of cement replacement materials such as fly ash. Furthermore, the use of admixtures such as ...

Chemical Admixtures - Portland Cement AssociationAll other varieties of admixtures fall into the specialty category whose functions include corrosion inhibition, shrinkage reduction, alkali-silica reactivity reduction, workability enhancement, bonding, damp proofing, and coloring. Air-entraining admixtures, which are used to purposely place microscopic air bubbles into the concrete, are discussed more fully in Air-Entrained Concrete. Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to ...

Precast Concrete Retaining Wall Systems - National Precast ...of a finished precast retaining wall system. The purpose of proper gradation is to produce concrete with a maximum density along with good workability to achieve sufficient strength. Well-graded aggregates help improve workability, durability and strength of the concrete. Poorly graded or gap-graded aggregates rely on the use of excess mortar to fill voids between course ag- gregates, leading to potential durability problems. Concrete mixes containing rounded coarse aggregates&nbsp;...
