Description The corrosion-resisting characteristics of reinforcement in cement blended with siliceous mineral wastes viz. gold tailing and flyash have been evaluated by using an accelerated corrosion technique. The additions of these mineral admixtures to cement varied between 0 and 20% with difference of every 5% results of the test show that the blending of gold tailing and flyash to cement significantly improves the corrosion resistance performance of concrete exposed to sea water. Maximum reduction in the corrosion resistance performance of concrete exposed to sea water. Maximum reduction in the corrosion rate was observed in the concrete mixed with 10% gold tailing together with 10% flyash. The corrosion rate and polarisation resistance of the control concrete specimen was found to be 0.258 mpy. 35.08 k omega -cm sup(2) respectively.
