Embodiment 1

[0013] 1. Take 96kg of sulphoaluminate cement clinker and 4kg of alkali, pour the above-mentioned sulphoaluminate cement clinker and alkali into a ball mill and stir evenly, and then pack it with a moisture-proof bag through a packaging machine. The net weight of each bag is 25±0.5 kg.

[0014] 2. Take 60kg of gypsum, 30kg of lime, 5kg of alum, and 5kg of quick-setting agent, put the above-mentioned gypsum and lime into the receiving hopper, pulverize and homogenize through the crusher and ball mill in turn, then add alum and quick-setting agent, and then stir through the mixer uniform, and then packed in moisture-proof bags by a packaging machine, with a net weight of 25±0.5kg per bag.

[0015] The application process of high water quick-setting material for mine is as follows:

[0016] 1. Pulping: Use two sets of special mud mixers equipped with water and feeding equipment to stir the above raw materials separately at the same time, pour 3 bags of the above-mentioned packa...

Embodiment 2

[0020] 1. Take 192kg of sulphoaluminate cement clinker and 8kg of alkali, pour the above-mentioned sulphoaluminate cement clinker and alkali into a ball mill and stir evenly, and then pack it with a moisture-proof bag through a packaging machine. The net weight of each bag is 25±0.5 kg.

[0021] 2. Take 120kg of gypsum, 60kg of lime, 10kg of alum, and 10kg of quick-setting agent, put the above-mentioned gypsum and lime into the receiving hopper, crush and homogenize through the crusher and ball mill in turn, then add alum and quick-setting agent, and then stir through the mixer uniform, and then packed in moisture-proof bags by a packaging machine, with a net weight of 25±0.5kg per bag.

[0022] The application process of high water quick-setting material for mine is as follows:

[0023] 1. Pulping: Use two sets of special mud mixers equipped with water and feeding equipment to stir the above raw materials separately at the same time, pour 6 bags of the above-mentioned packa...

Abstract

The invention provides a mine high-water quick-setting material which comprises the following raw materials in parts by weight: 96-288 parts of sulphoaluminate cement clinker, 4-12 parts of base, 60-180 parts of gypsum, 30-90 parts of lime, 5-15 parts of white alum and 5-15 parts of setting accelerator. The mine high-water quick-setting material has no toxicity and nocuity and is little in corrosivity and high in moisture content; the mine high-water quick-setting material is quick in coagulating speed, and the size forming the high-water material is coagulated within 20-40 minutes; and the early strength of the mine high-water quick-setting material is highly and quickly increased, and the mine high-water quick-setting material has high residual strength and good constant-resistance characteristic.

Description

technical field [0001] The invention belongs to a quick-setting material, in particular to a mine-used high-water quick-setting material. Background technique [0002] According to the group's long-term development and construction plan, the underground mining face has successfully implemented the gob-side entry retaining project, which has greatly increased the resource reserves of the mine. Because the group currently uses high-water quick-setting materials, all of them rely on outsourcing. After research and decision by the group, our group's building materials factory Carry out research and production of high-water materials. The existing traditional quick-setting filling materials generally have low moisture content of the filling body, slow solidification speed, low early strength, slow growth, single material setting within 24 hours, low residual strength and poor performance of the filling body. "Constant resistance" characteristics; technically unfeasible, economic...
