As we all know, civil engineering often need to use planting glue, but there are many kinds of planting glue, so when choosing, we don't know what kind of planting glue is suitable for us. Let's follow the editor to understand the classification and characteristics of planting glue~~
There are two kinds of glue: inorganic glue and organic glue.
1、 Organic planting glue
Organic planting glue is a kind of building structure bonding and strengthening material which is composed of synthetic resin, filling materials and chemical additives.
Features: strong anchoring force, simple construction, low cost of materials, corrosion resistance;
Scope of application: used for connection of new and old buildings, seismic reinforcement of buildings, anchorage of equipment foundation and reinforcement of brick concrete building structure.
Scope of application: Construction and installation, engineering seismic reinforcement, concrete reinforcement, bridge dike crack repair, etc.
The organic rebar adhesive is divided into modified epoxy and modified vinyl ester.
Modified epoxy rebar adhesive:
characteristic
1. Excellent aging resistance, chemical corrosion resistance and water resistance.
2. Fast bearing, high anchoring force and excellent durability.
3. The slip is small, and the base material separation and deformation can be controlled in time.
4. The adhesive does not contain volatile solvents and has low shrinkage after curing, which can be reduced to less than 1%.
Scope of application
1. It is used in the anchorage construction of various load-bearing and non load-bearing bolts and base materials such as concrete, brick wall and rock.
2. It is applied to the anchorage construction of steel bars planted on the base materials of concrete, brick wall and rock.
Modified vinyl ester adhesive for bar planting:
characteristic
1. High strength and strong adhesion.
2. aging resistance and good heat resistance, no creep at room temperature.
3. Low humidity sensitivity
4. Good acid and alkali resistance, anti-seismic performance, no expansion.
5. Good thixotropy, suitable for side or top anchorage.
Code for design of reinforcement of concrete structures (GB 50367) stipulates that the adhesive for planting reinforcement must be modified epoxy or modified vinyl ester (including modified carbamate). At present, a lot of construction teams are using unsaturated resin to produce steel planting glue. Although its price is cheap, its anti-aging performance and environmental protection are not as good as modified epoxy steel planting glue, and the operation time is short, so it is not easy to control in construction.
2、 Inorganic planting glue
characteristic
1. Green environmental protection: it does not contain styrene and other components of machine glue, does not produce harmful gas to indoor and outdoor environment after construction, and does not cause harm to construction personnel during construction;
2. Not afraid of water: the moisture and micro water in the planting hole will not hinder the construction;
3. High temperature resistance: it has higher high temperature resistance than organic glue, which can realize glue before welding, which greatly facilitates the requirements of actual construction; it can also be used for planting bars in high temperature places all year round; low temperature construction: it does not hinder the construction at - 3 ℃;
4. High strength: it has higher drawing force under the same planting anchor depth and construction conditions;
4. High strength: it has higher drawing force under the same planting anchor depth and construction conditions;
5. It is widely used in concrete, reinforced concrete, geotechnical engineering, houses, bridges, tunnels, tunnels, mines, dams, oil wells, ocean terminals, etc.
Whether it is organic or inorganic planting glue, they all have their own characteristics, we should choose the suitable one according to their characteristics and scope of application.
