CIVIL ENGINEERING: CONCRETE TECHNOLOGY (WORKABILITY

2011-9-7 · Workability is the ability of a fresh (plastic) concrete mix to fill the form/mold properly with the desired work (vibration) and without reducing the concrete's quality. Workability depends on water content, aggregate (shape and size distribution), cementitious content and age (level of hydration ) and can be modified by adding chemical admixtures, like superplasticizer.

2013-9-27 · The higher the aggregate/cement ratio, the leaner is the concrete. In lean concrete, less quantity of paste is available for lubrication, per unit surface area of aggregate and hence the mobility reduce. In case of rich concrete with lower aggregate/cement ratio, more paste is available to make the mix cohesive and fatty to give better workability.
