Problems solved by technology

However, this research result does not remove the alkaline ions of the saponification slag, and does not eliminate the alkalinization pollution caused by the saponification slag to the environment. Therefore, the research result of using saponification slag to strengthen the dredged soft soil cannot be used in engineering applications.

Embodiment 1

[0012] A kind of soft foundation solidification ash used for solidification of weak ground, it is composed of saponified slag and fly ash, and its volume percentage is m 3 : saponification slag: fly ash = 1: 0.1

Embodiment 2

[0014] Soft-based solidified ash, which consists of saponified slag and fly ash, by volume percentage m 3 : saponification slag: fly ash = 1: 0.6

Embodiment 3

[0016] Soft-based solidified ash, which consists of saponified slag and fly ash, by volume percentage m 3 : saponification slag: fly ash = 1: 0.3

[0017] The preparation method of soft base curing ash:

[0018] 1. Feeding

[0019] Including drying and stirring, the main function is to reduce the moisture content of raw materials and decompose calcium carbide.

[0020] Transport the saponified slag to the raw material yard. Take 750 cubic meters of saponification slag and put it into the drying yard, pile it up according to the ratio of length, width and height of 30:25:1, and stir it with a bamboo rake to accelerate the dehydration. After drying in the sun until the water content in the saponification slag is lower than 30%, put it into a stirring tank and stir until the particle diameter of the raw material block is less than 2 cm. Unqualified return to the drying link.

[0021] 2. Neutralization, washing and draining

[0022] It includes four steps of adding sulfuric ...

Abstract

The invention relates to a soft base curing ash, characterized in that the ash consists of saponification slag and coal ash at a volume percentage of rice3: saponification slag: coal ash= 1: 0.1-0.6, wherein the saponification slag is aired and mixed with hydric sulphate and water, and then mixed with coal ash after drained and aired, at last checked and packed after aired. The invention has advantages that the main materials of the invention are treated chemical industry waste materials as the saponification slag and the coal ash, and the invention can be extensive used in making ground in the sea or the river, weak ground treatment in the railway, the highway, or yards, and civil architectures. The invention not only can remit the pollution damage of the coal ash, but also improves the operating development in weak ground treatment therefore combines the making waste into useful with improving environment and creating economic profits.

Description

technical field [0001] The invention belongs to chemical building materials, in particular to a soft-base curing ash used for curing weak foundations. Background technique [0002] After the Binhai New Area was included in the national development strategy plan, the demand for construction land increased rapidly. Tanggu District reclaimed land to alleviate this contradiction. At present, land reclamation is mainly based on vacuum preloading, backfilling and overturning. The vacuum preloading method takes a long time, has high costs, and has a low load strength of the finished product, which is difficult to meet the infrastructure needs of large enterprises. The backfilling method needs to use a large amount of dry soil, which greatly increases the cost, and does not conform to the national policy of restricting excavation. The tumbling construction has been tested in practice, and it can meet the design requirements in terms of cost, environmental protection, and finished ...
