The influence of high-temperature curing on the compressive strength and chloride permeability of the concrete containing ground iron and steel slag (GISS) was investigated. Under standard curing condition (20°C), the early-age compressive strength of the concrete with GISS is much lower than that of the pure cement concrete. The activity of GISS is more sensitive to the increase of curing ...

Jan 01, 1995  At 28 days, silica fume concrete still had the highest strength with a value of 48-4 MPa. This was followed by 25% slag concrete, control con- crete, 50% slag concrete, HVFA concrete, and 25% fly ash concrete, respectively. The lowest compressive strength value at 28 days was 31-5 MPa for 25% fly ash concrete.

Slag cement strength

Slag cement has a particularly significant effect on the flexural strength of concrete. Flexural strength (or modulus of rupture) is one of the principal factors in concrete pavement design. Increased flexural strength is evident in Figure 2, where 50 percent slag cement achieved a 20 percent strength improvement, even though total cementitious ...
