Abstract

The invention belongs to the technical field of solidified soil, and particularly relates to environment-friendly solidified soil which comprises the following components in parts by weight: 60-80 parts of soil, 10-30 parts of cement, 10-30 parts of water-borne epoxy resin emulsion, 0.05-0.2 part of modified metal powder, 5-15 parts of a soil stabilizer, 5-15 parts of filler and 0-20 parts of water. According to the environment-friendly solidified soil, lime is not added, raised dust is avoided on a construction site, the influence on the environment is avoided, the added water-borne epoxy resin emulsion can play a role of a binding agent, the binding force among the substances is enhanced, inorganic materials can be effectively filled with the water-borne epoxy resin emulsion, and the strength is improved; the added modified metal powder can chemically react with some hydroxides in the solidified soil to generate salts and a small amount of gas, micro-expansion occurs, solidification shrinkage of the solidified soil can be effectively resisted through the micro-expansion effect, cracks can be reduced, and the strength is further improved.

Description

technical field [0001] The application belongs to the technical field of solidified soil, and in particular relates to an environment-friendly solidified soil. Background technique [0002] Solidified soil is to add a certain amount of cement, lime, curing agent, etc. to the soil to stabilize the soil, and then pave, roll, etc. to form a solid road surface. [0003] Chinese patent application document CN 104863038 A discloses a method for preparing lime cement solidified soil by using a soil curing agent. First, the soil curing agent is diluted with water to obtain a solution containing the soil curing agent, and then the solution containing the soil curing agent is mixed with soil and cement Mix evenly with lime to obtain a mixture, and roll the mixture to obtain lime cement solidified soil. The high-valent ions in the lime (Ca 2+ , Mg 2+ ) and low-valent cations in clay particles (K + 、Na + ) ion exchange reaction occurs, so that the plasticity index of the soil decrea...
