要旨 |
Using Blast Furnace Slag (BFS) with low water-binder ratio improves the performance of concrete but causes early-age cracking due to autogeneous shrinkage. The internal relative humidity (IRH) of mortar under ambient condition was measured by using new proposed method to study the effect of water-binder ratio and BFS in mixture on moisture loss. Decrement of IRH in mortar specimens having low water-binder ratio depends on moisture diffusion and self desiccation. Using BFS leads lower IRH compare to pure Portland cement mortar. |
