| Abstract: |
| The effect of steel slag powder on road properties and freezing and thawing resistance of concrete was studied.The results show that the concrete with steel slag powder can enhance road properties and freezing and thawing resistance of concrete.The flexural strength of concrete with 10% steel slag powder added can be increased by about 30%,brittleness coefficient can be decreased by 30% and abrasion resistance can be enhanced by 13%. |
| Key words: steel slag powder,road property,flexural strength,abrasion resistance,freezing and thawing resistance,drying shrinkage |
