Abstract

The invention discloses a mud curing agent. The mud curing agent comprises the following raw materials in part by weight: 30 to 50 parts of rapid-hardening sulfoaluminate cement, 40 to 50 parts of river sand, 5 to 15 parts of ground plaster, 5 to 15 parts of calcium chloride and 0.025 to 0.075 part of cellulose carboxyl material. A using method for the mud curing agent comprises that: the colloid system of the mud must be subjected to colloid breaking treatment by adopting a colloid breaker before the mud is cured, and the mud curing agent is added into the mud after colloid breakage according to a certain proportion, so the mud can be well cured. By effective curing treatment for the mud, the original lacking land resource of China is saved, and the curing of the mud is realized, so that other constructions can be performed after soil is covered for returning tillage or certain curing strength is met, and the mud curing agent has good economic and social benefits.

Example Embodiment

[0020] The specific gravity of the mud on site is 1.2g/cm 3 , The water content is 217%, and the breaker Al is added before the mud solidifies 2 (SO4) 3 , Its concentration is 10%, and the mixing amount is 6/1000 (mud mass ratio). A mechanical stirring device is used to stir the mud after adding the breaker evenly. After the mud colloid system is broken (the solid and liquid in the mud have been separated), the mud curing material is added for curing treatment. The content of the mud curing material is 20%-50% (mud Mass ratio), and then use a mechanical stirring device to stir the slurry evenly after adding the solidified material, and after solidification, cover the soil and return to plowing or carry out other construction operations such as erecting supports.
[0021] Table 1 shows the ratio of mud solidified materials.
