- about 1 wt % to about 10 wt % red mud;
- about 1 wt % to about 10 wt % cement;
- about 85 wt % to about 95 wt % epoxy resin comprising bisphenol-A-epichlorohydrin and an oxirane mono [(C12-14)-alkyloxy)methyl] derivative;
- and
- about 1 wt % to about 10 wt % crosslinker comprising diethylenetriamine (DETA).
