... [8][9][10] Utilizing inorganic cementitious materials, such as cement, for the solidification/stabilization of toxic waste can form a strong cementitious matrix through chemical binding or physical adsorption by hydration products. [11][12][13][14][15][16] The physical binding involves encapsulating or adsorbing waste residue within the cementitious material, while the chemical binding solidifies through bonding resulting from ion exchange with the gel substance. [11][12][13][14] This alteration in the waste's fluidity, compressibility, and strength reduces the leaching of toxic components. ...
