Embodiment 1

[0044] The ratio by weight is: 6 parts by weight of No. 425 ordinary Portland cement, 10 parts by weight of mineral powder, 8 parts by weight of water, 0.05 parts by weight of polyurethane, 0.02 parts by weight of sodium hydroxide, and 0.05 parts by weight of silane coupling agent. 0.1 parts by weight of hydroxyl liquid polybutadiene, 0.1 parts by weight of diethylaminoethanol, 0.3 parts by weight of silicon dioxide, and 0.02 parts by weight of fiber balls. After the above materials are mixed and stirred evenly, mix them with dredged soil according to the ratio of 20%: 80%, stir evenly and make molds for maintenance, and test the unconfined compressive strength under the ages of 3d, 7d, 14d, 21d, and 28d respectively , wear resistance, water absorption and frost resistance.

Embodiment 2

[0046] The ratio by weight is: 8 parts by weight of No. 425 ordinary Portland cement, 12 parts by weight of mineral powder, 10 parts by weight of water, 0.07 parts by weight of polyurethane, 0.04 parts by weight of triethanolamine, 0.07 parts by weight of silane coupling agent, terminal hydroxyl 0.12 parts by weight of liquid polybutadiene, 0.12 parts by weight of diethylaminoethanol, 0.4 parts by weight of silicon dioxide, and 0.03 parts by weight of fiber balls. After the above materials are mixed and stirred evenly, they are mixed with dredged soil according to the ratio of 20%:80%, stirred evenly, molded and maintained, and tested for unconfined compressive strength at ages 3d, 7d, 14d, 21d, and 28d respectively , wear resistance, water absorption and frost resistance.

Embodiment 3

[0048] The proportion by weight is: 10 parts by weight of No. 425 ordinary Portland cement, 14 parts by weight of mineral powder, 12 parts by weight of water, 0.09 parts by weight of polyurethane, 0.02 parts by weight of triethanolamine, 0.04 parts by weight of sodium hydroxide, silane coupling 0.09 parts by weight of agent, 0.14 parts by weight of hydroxyl-terminated liquid polybutadiene, 0.14 parts by weight of diethylaminoethanol, 0.5 parts by weight of silicon dioxide, and 0.04 parts by weight of fiber balls. After mixing and stirring the above materials evenly, mix them with the dredged soil according to the ratio of 20%:80%, stir evenly, make molds and maintain them, and test the unconfined compressive strength under the ages of 3d, 7d, 14d, 21d, and 28d respectively , wear resistance, water absorption and frost resistance.

Abstract

The invention provides an artificial ecological stone. The artificial ecological stone is prepared from, by mass, 6-12 parts of cement, 8-14 parts of mineral powder, 0.05-0.1 part of an adhesive, 0.02-0.1 part of an additive, 0.05-0.1 part of a silane coupling agent, 0.1-0.15 part of hydroxyl terminated liquid polybutadiene, 0.1-0.15 part of diethylaminoethanol, 0.1-1 part of silica, 0.01-0.05 part of fiber balls, 70-160 parts of dredged soil and 6-14 parts of water. The artificial ecological stone solves the problems about stacking and disposal of a large amount of dredged soil generated in adredging project, and the dredged soil can be quickly solidified to meet the strength requirement of engineering construction and reduce the cost; silica can reduce the pH value of the dredged soil and improve the water resistance and physical cementing capability of the ecological stone; the physical indexes such as compressive strength, wearing resistance, water absorption rate and freeze resistance of the ecological stone are superior to those of natural stone; the mixing ratio of the components can be reasonably adjusted to achieve the required construction strength, the cost is lowered to the greatest degree, the engineering properties of the ecological stone are improved, and the construction safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of stone production, and in particular relates to an artificial ecological stone and a preparation method. Background technique [0002] In the process of developing and constructing rivers, rivers, lakes, seas and other spaces, reclamation of seas, channel dredging and dredging, and opening of new channels, 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] As a high-grade building decoration material, stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction. In the past 20 to 30 years, the international stone industry has d...
