Long Term Performance of Alkali Activated Slag Concrete
centration level of Na2O is 5% by slag mass in the AAS mix. The design for each mix was for a 28-day strength of 40 + 10 MPa. A water binder ratio (w/b) and water solid ratio (w/s) of 52% and 46% were used to prepare the AASC1 respectively. As comparison, the data of alkali activated slag concrete (AASC2) and Portland Cement concrete (Control) from
