Problems solved by technology

Because it takes a long time for cement to form a solidified body with the mudstone mud, and the strength of the finally formed solidified body is low, the effect of using cement to reinforce the mudstone mud is usually not ideal
When the water content of the mudstone silt is high, the effect of lime on its reinforcement is not good, and there will be disadvantages that the strength of the reinforced object is low and the amount of lime is too large

Embodiment 1

[0029] Sulphoaluminate cement clinker, gypsum, slaked lime, sodium sulfate, sodium silicate, aluminum potassium sulfate and sodium hydroxide are mixed and ground according to the components specified in Table 1 below to form a specific surface area of ​​200m 2 / kg~900m 2 / kg of powder.

[0030] Under normal temperature and pressure, 15% by weight of the above-mentioned curing agent is mixed into the mud rock mud compound with a water content of about 50% to form a cured product. Then, the curing time, unconfined compressive strength and failure strain of the obtained cured product were tested under standard curing conditions and water immersion curing conditions, and the test results are listed in Table 1.

Embodiment 2

[0032] The method of Example 1 was repeated according to the content of each component specified in Table 1 below, and the test results are listed in Table 1.

Embodiment 3

[0034] The method of Example 1 was repeated according to the content of each component specified in Table 1 below, and the test results are listed in Table 1.

Abstract

The invention relates to a rapid high-strength hardener composition for a pelitization substance of mudstone of a laneway base plate of a mine and a method for preparing the same. The composition is prepared through mixing and grinding sulphate aluminium cement clinker, hydrated gypsum, hydrated lime, sodium sulfate, sodium silicate, aluminum potassium sulfate and sodium hydroxide into powder with specific surface area of between 200m<2> / kg and 900m<2> / kg. The rapid high-strength hardener composition carries out reinforcing treatment on the pelitization substance of mudstone and has the advantages of short time for forming a condensate and high strength of the formed condensate.

Description

technical field [0001] The invention relates to a curing agent composition and a preparation method thereof. More specifically, the invention relates to a rapid high-strength curing agent composition specially used for mudstone mud on the floor of mine roadways and a preparation method thereof. Background technique [0002] The floor of the mine roadway is mostly composed of mudstone or mud shale. When the mudstone meets water, under certain conditions, it will form mudstone muddy matter similar to silt, which will soften and disintegrate, which makes the mine roadway floor become muddy. The muddy roadway floor will seriously hinder the passage of equipment and vehicles, affect the construction and operation environment of the roadway, and have a great impact on the speed of roadway excavation, resulting in serious economic losses. [0003] In order to solve the above problems, for the treatment of the mudstone silt, usually after the mudstone silt is dredged, it is transpor...
