Concrete

Workability can be measured by the concrete slump test, a simple measure of the plasticity of a fresh batch of concrete following the ASTM C 143 or EN 12350-2 test standards. Slump is normally measured by filling an "Abrams cone" with a sample from a fresh batch of concrete. The cone is placed with the wide end down onto a level, non-absorptive surface.

bond, and thus creating a st ronger hot mix asphalt or portland cement concrete. Surface texture also affects the workability of hot mix asphalt, the asphalt requirements of hot mix asphalt, and th e water requirements of portland cement concrete. Some aggregates may initially have good surface texture, but may polish smooth later under traffic.

Slump Loss - an overview

It was stated that the operators of the ready-mix plants had difficulty with determining the effective w/c ratio and consequently produced mixes with extremely different levels of workability, wherein the RAC from one of those companies (mix 1 in Fig. 7.5) showed larger slump losses with increasing RA content. However, the two other mixes ...

Quality and Durability of Concrete

Thus, different grades of concrete i.e. M20, M30, M70 etc. can be produced. Without altering the water content or water binder ratio for a particular grade of concrete, the workability of concrete can be increased with the use of superplasticizers.
