Slag concrete

Schiacken-auge, n. = Schlackenloch. -beton, tn. slag concrete. 

Like HP/HVFAC, high-performance/high-volume slag concrete (HP/HVSC) has a very low water-cement ratio...

Slag- Concrete cement that sometimes covers the vertical face of the foundation void material. 

In a given set of conditions in terms of humidity and temperature and provided corrosion has initiated, the higher resistivity of blended cements results in a lower corrosion rate than for Portland cement As an illustration, the resistivities and corrosion rates measured on the previously mentioned concrete blocks exposed in a marine-splash zone have been shown in Table 6.2. Bars at 20 mm depth in fly ash and blast furnace slag concrete show low corrosion rates although the chloride contents suggest corrosion initiation has taken place both have a high resistivity (> 500 fl m). Bars at 20 mm in Portland cement blocks show much higher corrosion rates, associated with low resistivity (< 100 O m) [32].

The resistanee of slag concrete to sulfate is increased if more than 65% eement is replaeed by slag at a constant gypsum addition of 5%. The high resistanee to sulfate attack can be attributed partly to lower permeability of eonerete.
