By hydration and vaporization, water is absorbed by
aggregates and mobility decreases accordingly.

Time
Fig.4.2.5 Relationship between Slump and Time
The relationship between slump and time is shown in
fig4.3.5. Slump decreases while time increases. Slump
test should be proceeded in 15 minutes after preparation
of the composite in construction.
Influence from Temperature
• Mobility decreases with temperature rising
– Temperature must be noticed to get required workability
– More mixed water in summer should be used than that in winter
