Abstract: The compressive strength,and pH values in immersed seawater were examined in congealing stones made of mine tailings(ratio of water to mine tailings=0.60,S1;0.55,S2;0.49,S3;and 0.44,S4)reference to cement(ratio of water to cement=0.60,C1;0.55,C2;0.49,C3;and 0.44,C4)to explore the feasibility of the congealing stone as artificial reef materials.The results showed that 1)the intensities in 28 day conservation in freshwater were found higher in the congealing stone groups(S1,S2,S3,S4)than those in the concrete groups except for in group S4.The intensity of the module was shown to be increased first and then decreased with the increase in water cement ratio.Apart from C4,there were higher intensities in the concrete groups than those in the congealing stone groups significantly,with the procedure of being immersed in the sea water.2)the intensities in 60 day conservation in seawater were found to be higher than those in the cement group while the intensities in 30 day conservation in seawater,there were except in S4 and C4.The pH values of 8.84,8.87,9.10,and 8.95 were found in the congealing stone groups immersed in the sea water,and the pH values of 10.42,10.44,10.80,and 10.72 in the cement group immersed in the sea water,lower than in the concrete group with the same water cement ratio.From the above rsults,it is concluded that the congealing stones can be used as the artificial reef materials, with superior to concrete.
