Novel high-strength dredged soil curing agent

Abstract

The invention provides a novel high-strength dredged soil curing agent. The novel high-strength dredged soil curing agent comprises the following components in parts by weight: 6-12 parts of cement, 8-14 parts of mineral powder, 0.05-0.1 part of a binding agent, 0.02-0.1 part of an additive, 0.05-0.1 part of a silane coupling agent, 0.1-0.15 part of hydroxy-terminated liquid polybutadiene, 0.1-0.15 part of diethylaminoethanol and 0.01-0.05 part of fiber balls. By the novel high-strength dredged soil curing agent, the problem that a large number of dredged sand is difficult to stack and treat in dredging engineering is solved, furthermore, the dredged soil can be cured rapidly and then meets the requirement for the strength of engineering construction, and the cost is saved; according to difference of a construction position, the blending ratio of the curing agent can be adjusted reasonably to achieve the required construction strength, the cost is reduced to a maximum extent, engineering characters of cured soil are improved, and construction safety is ensured; and the using amount of the cement is reduced greatly, an environment is protected, and sustainable development is realized.

Description

technical field [0001] The invention belongs to the technical field of curing agents, in particular to a novel high-strength dredging soil curing agent. Background technique [0002] In the process of developing and constructing spaces such as rivers, rivers, lakes, and seas, reclamation of land from the sea, dredging and dredging of waterways, and opening new waterways, a large amount of dredged soil is usually produced. These dredged soils have high water content, high compression, and low bearing capacity, which have a great impact on the project. After curing the dredged soil with a curing agent, its mechanical properties are significantly improved, and it can be used in road bedding projects and slope reinforcement projects. [0003] The commonly used soft soil curing agent is mainly cement. However, due to the massive exploitation of non-renewable resources in the production process of cement, the pollution of air and water resources limits the further use of cement....

AI Technical Summary

Problems solved by technology

However, due to the massive exploitation of non-renewable resources in the production process of cement, the pollution of air and water resources limits the further use of cement.

In the existing technology, either the strength of the solidified soil is still too low, the reaction time is too long, or the scope of application is too narrow to meet various types of large-scale projects.
