Is UEA ordinary concrete?

UEA is a U-shaped expansive agent, not concrete. The English name is U-shaped expansive agent concrete, abbreviated as United Expansing Agent or UEA, which is made of aluminum sulfate, aluminum oxide, aluminum potassium sulfate, etc. As the main source of expansion.

Technical indicators:

1. Appearance: grayish white powder with natural bulk density of 65438±0g/ml.

2. The limited expansion rate is 2-4/ 10,000, and the self-stress value is 0.2-0.8 MPa.

3. Compared with ordinary concrete, concrete mixed with UEA low alkali expansive agent has early strength.

4. Impermeability grade: 65438+ is 0-2 times higher than ordinary concrete.

Main uses:

1. Underground buildings: such as underground parking lots, underground warehouses, tunnels, mines, civil air defense projects, underground sidewalks, machine tunnels, etc.

2. Build pools, swimming pools, water towers, storage tanks, large containers, granaries, oil tanks, storage warehouses in caves, etc.

3. The structure is self-waterproof rigid roof, mortar impervious layer and mortar moisture-proof layer.

4. Grouting materials for precast members, anchorage of frame structure joints, pipe joints and post-tensioned precast members, post-pouring and backfilling of structures, and grouting materials for rock foundation.

5. Important buildings with good crack resistance and beautiful appearance, such as stadium stands, urban sculptures, monuments, museums and hotels.
