specific Embodiment approach 2

[0026] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in this embodiment, in order to optimally improve the strength of graphite tailings concrete, the particle size of the stone is 5-40.5 mm, and the particle size of the sand is 0.16 mm. ~5mm (medium sand), the particle size of graphite tailings is 0.2~0.4mm.

specific Embodiment approach 3

[0027] Embodiment 3: The difference between this embodiment and Embodiment 1 is that in this embodiment, the water reducer is a naphthalene-based high-efficiency water reducer. The water reducer can be a naphthalene-based high-efficiency water-reducer, a polycyclic aromatic salt-type water-reducer, or a polycarboxylate water-reducer. In order to reduce costs, the water-reducer in this embodiment is a naphthalene-based high-efficiency water reducer.

Abstract

The invention relates to a graphite tailing concrete mixture and a preparation method thereof and relates to the technical field of building materials. The invention aims to solve the problems of environmental pollution caused by graphite tailings and shortage of building sand. The graphite tailing concrete mixture is prepared from 346.15 parts of cement, 1284.1 parts of stone, 330.20-550.33 partsof sand, 59.97-239.88 parts of graphite tailings, 1-1.3 parts of water reducer and 180 parts of water. The preparation method comprises the following steps: 1) preparing raw materials, and 2) uniformly stirring and mixing the raw materials and then curing, thereby acquiring the graphite tailing concrete mixture. The graphite tailing concrete mixture is high in concrete strength; the invention provides a new treatment method for the pollutant graphite tailings; the environmental pollution can be reduced; the problem of shortage of building sand can be solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a graphite tailings concrete mixture and a preparation method thereof. Background technique [0002] Graphite is a very common substance in human life. As early as the 1930s, my country began to produce and process graphite. With the maturity of mining technology, the amount of graphite tailings mining in my country has increased significantly, but while obtaining important graphite resources, tailings products that pollute the environment have also appeared. Green concrete is one of the main directions for the development of concrete technology today. With the accelerated mining of graphite, a large amount of graphite tailings will be produced every year, which not only pollutes the environment but also wastes resources. At the same time, the amount of existing construction sand can no longer meet the increasing amount of concrete structure construction, and a new ty...
