| Abstract: | Alkali activated slag Pavement concrete (AASPC)is made from activating industrial slag (fly)ash,mineralslagandgroundgranulatedblast-furnaceslag(GGBS)withouttheuseofanyPortlandcement as binder and GGBS gravels and GGBS sands are used as fine and coarse aggregates to take the place of natural gravels and sand. The effects of proprotion of alkali solution on the strength and workability of AASPC are investigated. The results show that with proper workability, the 28 day compressive strength of 44 MPa at flexural strength of 8.3 MPa are obtained at the age of 28 days. |
