Abstract

This is an essay in the field of ceramics and composites. In order to study the effect of activated gold tailings content on the mechanical properties, microstructural properties and hydration properties of concrete, the mechanical properties, XRD, TG-DTG and hydration characteristics tests of different content of gold tailings concrete were carried out. The results showed that when the grinding time was 30 min, the specific surface area of the gold tailings reached the maximum and the crystallinity reached the minimum. When the content of gold tailings was 30%, the basic mechanical and physical properties of concrete reached the best state. In addition, the microstructure performance, hydration heat release rate and heat release of concrete mixed with active gold tailings are better than those of concrete mixed with inactive gold tailings. With the continuous increase of the grinding time of gold tailings, Changing law of the cumulative curve of gold tailings particle size showed a trend of first increasing and then becoming stable. And with the continuous increase of grinding time, the accumulation of gold tailings particle size was getting larger and larger.
