After Solid, reinforced concrete buildings have minimal adaptability for modifications or alterations, which makes it challenging to adapt to transforming design and style requirements or potential expansion requirements.
Workability may be measured via the concrete slump examination, an easy measure in the plasticity of a refreshing batch of concrete adhering to the ASTM C 143 or EN 12350-2 test specifications. Slump is Commonly measured by filling an "Abrams cone" with a sample from the new batch of concrete. The cone is placed with the vast conclude down on to a amount, non-absorptive area.
