Study on the Influence of Graphite Tailings on the Properties of Foamed Concrete

This article presents the application of untreated graphite tailings in foamed concrete by studying the properties of graphite tailings. It also investigates the effects of raw materials, water–cement ratio, and curing methods on the density, strength, and frost resistance of graphite tailings foamed concrete. The test results show that the strength of foamed concrete can be improved by adding graphite tailings, and the optimal content is 25%–30%. The workability and strength of graphite tailings foamed concrete are optimized when the water–binder ratio is 0.39. The addition of 10% granulated blast‐furnace slag (GGBFS) can improve the compressive strength of graphite tailings foamed concrete. The standard curing conditions are more conducive to improving the strength of graphite tailings foamed concrete.
