Plastic Shrinkage Cracking:
While concrete is in it's elastic state a significant amount of
stress is present due to rapid evaporation of the water content within
the mix. While the concrete is curing, it's ability to adhere to bar or
mesh type reinforcing is impaired causing the matrix to slip over the
reinforcing, thus significantly increasing the risk of cracking. The
RAD19FF is distributed evenly throughout the mix and aids in binding the
concrete together in the early curing stages maximising crack control.
Description of Spalling:
The heating of a concrete structure as a result of fire is a serious
concern as any retained moisture within the concrete causes expansion
resulting in smaller pieces of concrete to explode from the surface.
This process repeats itself during the fire causing significant damage
to the structure. During a fire the Spalling process can start within
the first 15 minutes with a surface temperature of just 200 degrees
Celsius.
Benefits In Cases of Fires:
At 160 degrees Celsius the fibres melt creating a vast number of voids
allowing the retained moisture to escape in a non destructive manner,
significantly reducing any increase in pressure within the concrete
structure. Adding 1 kg of RAD19FF to a cubic metre of concrete is a very
cost effective method of fire protection for concrete structures.
