Compressive Strength Copper Ore

Compressive Strength Copper Ore. Fig. 2 shows the compressive strength of copper tailing-based geopolymers as a function of curing temperature. The 3 d compressive strength was similar to the 28 d compressive strength of geopolymers cured at all selected temperature indicating that geopolymeriation is a rapid reaction as observed in many previous studies Duan et al.
