Clay reinforcing paste slurry

Abstract

The invention relates to clay reinforcing paste slurry. The existing clay reinforcing paste slurry has poor anti-erosion performance in flowing water; in order to reduce the material mobility, the addition of modifying agents is more, so that the use cost is very high. The clay reinforcing paste slurry is characterized by being prepared from the following ingredients in parts by mass: 20 to 40 of clay raw slurry, 15 to 20 of cement, 10 to 20 of silicate minerals, 3 to 10 of additives and the balance water; the additives are aluminium potassium sulfate, sodium fluosilicate, sodium metaaluminate and calcium chloride. The clay reinforcing paste slurry has the advantages that the slurry controllability and the water-flow-erosion-resistant performance of the paste slurry are improved; the stone forming rate and the anti-seeping performance of a formed stone body are improved; the cost is lower; the problems of operation instability of bentonite in ordinary cement bentonite paste slurry and the like are solved.

Description

technical field [0001] The invention relates to reinforcement materials in the engineering field, in particular to a clay reinforcement paste. Background technique [0002] The existing clay-reinforced slurry has poor erosion resistance in moving water. In order to reduce the fluidity of the material, a large amount of modifier is added, resulting in a rather high cost of use. The cost of the modifier exceeds the cost of cement. As a result, the application is limited; in the application process, it is also found that the early strength of the clay cement paste with modifiers increases slowly. It is used in the case of large-scale and large-scale projects. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems, and provide a kind of clay reinforcement paste, which has good impact resistance, increased strength, low price and environmental protection. [0004] The technical solution adopted in the present ...

In order to reduce the fluidity of the material, a large amount of modifier is added, resulting in a rather high cost of use. The cost of the modifier exceeds the cost of cement. In the process of application, it is also found that the early strength of clay cement paste with modifiers increases slowly. After the slurry is poured into the formation, it is easy to be washed away by water, and it is difficult to form a complete curtain, so it is not suitable for large-scale Use in the case of scope and large amount of engineering
