Effect of Carbonization Impact on Compressive Strength of Cement-Fly Ash Mortar Subjected to Freeze-Thaw Cycles

Abstract:

The effect of carbonation on compressive strength of cement-fly ash mortar which subjected to freeze-thaw cycles were investigated by means of orthogonal design method. The results show that carbonization time is the main factors affecting compressive strength of cement-fly ash mortar subjected to freeze-thaw cycles, followed by the water-cement ratio, the number of freeze-thaw cycles and mix amount of fly ash. Carbonization improves the frost resistance of concrete in some extent, and in a reasonable range, the longer carbonation time is, the stronger frost resistance capacity is.
