Alkali slag anchoring material

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...
