Abstract

It is known that the bleeding phenomenon during the paste filling of the low concentration full tailings may result in the blocking of pipes, afterwards, the inhomogeneous distribution of strength and volume shrinkage of the filling body. For solving the above problems, orthogonal tests were designed for revealing the effect of tailing gradation, amount of binding material, slurry concentration and content of anti-bleeding material on bleeding rate by means of electrical resistivity test (ER), SEM-EDS and XRD. The results show that the bleeding rate of filling materials is inversely proportional to the tailing gradation, amount of binding material, slurry concentration and the content of anti-bleeding material. The concentration of slurry and the content of water solidifier had a great influence on the bleeding rate. By adding 5% anti-bleeding material equivalent to the total amount of glue-powder, the initial viscosity reduced by 30%, the 2 h viscosity reduced by 53%, the bleeding rate can be reduced by 10% and the 28 d compressive strength increased by 20% for the filling body. The anti-bleeding material improves the porosity of the, increases the concentration of SO₄^2- and pH value of the hydration system of the filling body, as well as generates ettringite, trapezium, C-S-H gel and silicoaluminate gel, which consumed a lot of free water, improves system stability by entangling molecules so that improves the bleeding situation for the filling body.

Key words: composite anti-bleeding material orthogonal tests bleeding rate microscopic mechanism
