- Slag cement improves the properties of fresh cast
concrete. Texture of concrete produced from slag cement is
maintained with less water addition compared to concrete produced
from Portland cement. This is an aspect that contributes the
handling of fresh concrete directly and its resistance and
durability indirectly.
- Heat of hydration of slag cement is
lower compared to Portland cement. Thus, in massive concrete
castings, slag cement is
preferred in order to prevent thermal shrinkage cracks and
other crack risks. Use of slag cement in hot weather conditions
is also advantageous.
- Durability of mortars and concretes
made by slag cement is higher compared to those made by Portland
cement of same
fineness in the long term.
- It has been demonstrated that slag
cements are more resistant to seawater compared to other cements.
Therefore, it is more
suitable for being used in constructions on the waterfront
and on the sea.
- It has been demonstrated that slag cements
are more resistant to the destructive effects of waters containing
acids, sulphates
and chlorine. The definite superiority of slag cements, particularly
to chlorine permeability and sulphate effect is well known.
-
Another superiority of slag cement is the positive effect on
keeping volumetric stability against alkaline-silica reaction.
As slag/clinker ratio increases, the positive effect becomes
more apparent.
