■ Reinforcement for advertisement boards,the noise barriers&barricades

 

Advantages of Glue for Concrete

 

■ Modified epoxy resin, no styrene
■ High strength & modulus, good toughness
■ Aging resistance & thermal resistance
■ Moisture tolerant, stable in a humid environment
■ Acid & alkali resistance
■ Seismic resistance, no expansion forces
■ Excellent thixotropy, suitable for side and top anchoring
■ Binocular straight mixed package, with special electric caulking gun and static mixer

 

Package of Glue for Concrete
13.32oz (390 ml) / piece, 30 pieces / carton
Shelf Life
When stored correctly, the shelf life will beat least 12 months from the date of manufacture.
Storage Conditions
Cartridges should be stored in their original packaging, the correct way up, in cool conditions (+50°F to +77°F) and out of direct runlight.

The Detailed Construction Process of Structure Anchor Adhesive 

 

1. Mark Up Hole Position and Drill Hole:

Drill holes in designed position. The depth and dismeter of the hole should meet the requirements in order to meet bonding area and ensure the pulling strength.

 

2. Clean Hole:

Clean and blow holes. Brush and blow for three times at least is recommended.

 

3. Glue Preparation:

HM-500 is equipped with a special static mixer and dispenser. Squeeze out the glue without fully mixed in the front part of the cartridge.

 

4. Injection:

Inject the glue from the bottom of the hole untill fill the two-third of the hole.

 

5. Rust Removal of Steel Rebar:

Polish the steel bar or anchor bolt before inserted through the hole.

 

6. Anchoring:

Inserting in one single direction untill to the bottom of the hole.

 

7. Standing and Curing:

Keep stand for maintenance before curing.

 

Note: HM-500 Anchoring Adhesive can be equiped with the following materials: screw thread steel, round steel, lead screw,threaded rod, anti-crack anchor.

 

Attention of Glue for Concrete

 

Proctive measures such as wearing masks, gloves, goggles etc., is necessary. Do not expose outside for longtime. If it is swallowed or dipped into eyes, please seek medical service at once

Notes:
1. Contcrete strength is C30,II grade steel yield strength is 335 N/mm2.
2. The diameter of drilling holes in the table is the best recommended value,the nearest bit can be selected according to the situation.
3. The yield buried depth value of the steel bars should consider safety factors,and select the design values.

Notes:
1. Concrete strength is C30,the designed strength of grade II steel bar is 310 N/mm2.
2. The designed safety coefficient of steel barys=1.15,the designed safety coefficient of concrete yc=1.5.
