Embodiment 1

[0024] The alkali slag anchoring material for rebar planting in this embodiment includes powder and water. The powder includes mineral powder, clinker and fine sand. The water is prepared by mixing potassium fluoride solution and sodium silicate solution. The mass ratio of water and powder is 0.375.

[0025] In this example:

[0026] The mass ratio of clinker and mineral powder in the powder is 1:9, and the mass ratio of the gross weight of clinker and mineral powder to fine sand is 1:1;

[0027] The mass ratio of the potassium fluoride solution and the sodium silicate solution in the water agent is 1:3.

[0028] In this embodiment, the water glass has a modulus of 1.5, a density of 1.30 g / mL, and a density of the potassium fluoride solution of 1.30 g / mL.

[0029] Raw materials used in this embodiment are as follows:

[0030] 1. Mineral powder: water-quenched blast furnace slag from the coal and iron plant of Chongqing Iron and Steel Group. After drying and grinding, the re...

Embodiment 2

[0046] The difference between this example and Example 1 is that the mass ratio of the potassium fluoride solution and the sodium silicate solution in the aqueous solution described in this example is 1:4.

Embodiment 3

[0048] The difference between this embodiment and embodiment 1 is that the mass ratio of clinker and mineral powder in the powder described in this embodiment is 2:8, and the mass ratio of potassium fluoride solution and sodium silicate solution in the water agent is 1 :4.

Abstract

The invention discloses an alkali slag steel bar anchorage material which comprises powder and a water agent. The powder and water agent are uniformly mixed when in use. The powder comprises ore powder, clinker and fine sand. The water agent is prepared by mixing a potassium fluoride solution and a sodium silicate solution. The mass ratio of the water agent to the powder is 0.30-0.45. The mass ratio of the clinker to the ore powder in the powder is 1:9-4:6. The mass ratio of the total weight of the clinker and ore powder to the fine sand is 0.8-1.2. The mass ratio of the potassium fluoride solution to the sodium silicate solution in the water agent is 1:4-1:3. The steel bar anchorage material has the advantages of high strength, favorable durability, high bondability with steel bars, low price and no toxicity, is convenient for construction, and can be widely used in steel bar anchorage of building construction engineering, water conservancy and hydroelectric engineering, road and bridge engineering, and the like.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a mortar containing an inorganic binder, in particular to an alkali slag planting reinforcement anchoring material. Background technique [0002] Rebar planting technology is a kind of building reinforcement and transformation technology, which has the advantages of flexible design, precise positioning, and simple construction. Its research and development has become a very dynamic branch of modern building structure reinforcement and transformation technology. [0003] Anchoring materials have an important impact on the reliability of reinforced planted bar structures. At present, anchoring materials for planted bars are mainly divided into organic bonding materials and inorganic bonding materials, with organic bonding as the main type. Organic bonding materials mainly include epoxy resin, polyester resin glue, vinyl resin glue, etc., which have the advantages of high early stren...
