Problems solved by technology

[0003] At present, stone powder materials are mainly used as filling materials. Because stone powder itself is a loose powder material with poor bonding performance, it cannot be directly solidified into a high-performance and environmentally friendly basic building material. There is no effective solution for this. solve the above problems

preparation example Construction

[0026] In a more preferred embodiment, a method for preparing a stone powder material curing agent, comprising: fully mixing the components of the stone powder material curing agent in the above ratio, and mixing 80 kg to 150 kilograms of the stone powder material solidifying agent mixed and stirred evenly.

[0027] In a more preferred embodiment, a method for preparing a stone powder material curing agent, the water content of the stone powder material curing agent mixed with the stone powder ranges from 7% to 30%.

Embodiment 1

[0030] The percentage by weight of each component in this embodiment is 40% of fly ash; 15% of cement; 20% of mineral powder; 20% of lime; 4% of gypsum; Fully mix the components of the stone powder material curing agent in the above ratio, and mix 134 kilograms of the stone powder material curing agent mixed into each cubic meter of stone powder and stir evenly; after the stone powder material curing agent is mixed with the stone powder The moisture content is controlled at 15% ± 1%. The stone powder involved in this implementation case is limestone powder, the fineness is in the range of 0.08 mm to 1.5 mm, and the particle size distribution is relatively uniform. After the stone powder is cured, the unconfined compressive strength reaches 2.41MPa at 7 days, 2.95MPa at 14 days, and 3.38MPa at 28 days. At the same time, the dry-wet cycle performance of stone powder-cured products is basically tend to be stable.

Embodiment 2

[0032] The percentage by weight of each component in this embodiment is 35% of fly ash; 20% of cement; 23.7% of mineral powder; 18% of lime; 3% of gypsum; Fully mix the components of the stone powder material curing agent in the above ratio, and mix 143 kg of the stone powder material curing agent in each cubic meter of stone powder and stir evenly; after the stone powder material curing agent is mixed with the stone powder The moisture content is controlled at 11% ± 1%. The stone powder involved in this implementation case is limestone powder, the fineness is in the range of 1.5 mm to 2 mm, and the particle size distribution is relatively uniform. After the stone powder is cured, the unconfined compressive strength reaches 2.65MPa at 7 days, 3.21MPa at 14 days, and 3.63MPa at 28 days. At the same time, the dry-wet cycle performance of stone powder-cured products is basically tend to be stable.

Abstract

The invention relates to the technical field of the gravel particle materials and specifically discloses a stone powder material curing agent and a preparation method thereof. The stone powder material curing agent comprises the following components in percentage by weight: 25-55% of coal ash, 10%-30% of cement, 10%-25% of mineral powder, 5%-20% of lime, 1%-5% of gypsum and 0.3%-1% of activator; the preparation method comprises the following steps: mixing the components of the stone powder material curing agent proportioned above thoroughly and evenly, and then blending stone powder per cubic meter with 80g to 150kg of mixed stone powder material curing agent and stirring evenly; the moisture content range of the stone powder material curing agent after being mixed with the stone powder is from 7% to 30%. The stone powder material curing agent is capable of effectively solidifying various stone powder materials to meet the requirements for building materials in engineering construction, for example, a pavement surface course material having high requirement for strength; as a result, the utilization efficiency of the stone powder materials is improved, and the cost of the engineering construction is also reduced while resources are saved.

Description

technical field [0001] The invention relates to the technical field of sand and gravel powder materials, in particular to a stone powder solidifying agent in sand and gravel powder improvement materials and a preparation method thereof. Background technique [0002] Stone powder is a general term, stone powder, there are many types of stone, there are many varieties according to the mineral composition, not necessarily calcium carbonate. Calcium carbonate is limestone, which is just a kind of stone powder. There is also talcum powder in the stone powder, which is used to make putty. There is also quartz powder, which is used to make glass. There are also many rocks with mineral components, which can be ground into powder for different processes and purposes. Stone powder has a wide range of uses, and products made from it can be seen everywhere in our lives, such as: plastics, calcium tablets, cosmetics, clothes, toothpaste, etc. Stone powder is also an important building...
