[0037] Gypsum: produced by Nanjing Jiangnan Cement ...

Embodiment 2

[0048] The mass percentages of each component in the test material and curing agent of this embodiment are the same as in Example 1, except that in the second step of the test method, the mass ratios of curing agent and coastal soft soil are different. In this embodiment, the mass ratio of curing agent to coastal soft soil is 8:92. The experimental results are shown in Table 3.

Embodiment 3

[0050] The mass percentages of each component in the test material and curing agent of this embodiment are the same as in Example 1, except that in the second step of the test method, the mass ratios of curing agent and coastal soft soil are different. In this embodiment, the mass ratio of curing agent to coastal soft soil is 12:88. The experimental results are shown in Table 3.

Abstract

The invention discloses a curing agent for littoral-facy soft soil. The curing agent consists of the following components in percentage by mass: 35-45% of cement, 35-45% of carbide slag, 15-20% of gypsum and 1-5% of surfactant. The main components of the curing agent come from industrial waste, and the cost is low; and meanwhile, compared with the cement curing agent, the curing agent disclosed by the invention has a better effect on curing the littoral-facy soft soil, and the engineering properties required for curing the littoral-facy soft soil can be realized.

Description

technical field [0001] The invention relates to a civil construction material, in particular to a curing agent for coastal soft soil. technical background [0002] Soft soils in my country's coastal areas are widely distributed, and generally have the characteristics of high water content, high compressibility, high void ratio, low strength, low permeability, high sensitivity, large disturbance, and remarkable rheological properties. At the same time, the existence of salt and organic matter in the soft soil of coastal facies makes the structure and composition of the soil relatively complex, and the physical and mechanical properties are quite different. The reinforcement and utilization of coastal soft soil has become one of the key technical issues in the treatment of coastal soft soil foundation. [0003] At present, there are many treatment methods for coastal soft soil, among which shallow solidification treatment and deep mixing pile treatment are commonly used. The...
