Ground granulated blast furnace slag (GGBFS) and fly ash (FA) are two common supplementary cementitious materials used in concrete mixtures. The Arkansas Highway and Transportation Department (AHTD) limits the use of GGBFS and FA in the Standard Specifications for Highway Construction. These limits are lower than those being used successfully in other parts of the United States and the world. The amount of replacement of cement by weight allowed for GGBFS is 25% and for FA is 20%, while no ternary mixtures are allowed. Research was done to determine, using materials common and native to Arkansas, if the limits could be changed and to what extent of change is reasonable.
