| Abstract: |
| At steam curing and moist curing conditions, the mechanical properties of concrete with different fineness and different proportions of ultrafine fly ash slag composite were studied. The experimental results indicate that the addition of ultrafine fly ash slag composite improves the long term mechanical properties of steam curing concrete. The concrete with ultrafine fly ash slag composite has lower drying shrinkage compared to that of control concrete. |
