Principle of operation and dosage:
Active expansion agents react with cement slurry to produce gas, increasing the apparent volume of cement and mortar. They can be used to make compensation shrinkage concrete, self-compacting concrete, with a free expansion rate of 0.02%~0.06% and a self-stress value of 0.2~0.6MPa, enhancing compressive strength by 10%~30%, and improving impermeability by 2~3 times. Widely applicable in industrial and residential buildings for waterproofing, expanded concrete, mortar, and cement products, they can induce a certain volume expansion in concrete, reducing the amount of cement in concrete and mortar. The dosage is 2%~4% of the cement用量.
Main Application:
1. Underground structures such as underground parking lots, warehouses, tunnels, mines, civil air defense facilities, pedestrian walkways, bunkers, and subway systems.
2. Constructing ponds, swimming pools, water towers, storage tanks, large containers, grain silos, oil tanks, and underground storage facilities.
3. Waterproof rigid waterproof roof mastic and moisture-proof layer.
4. Anchored pipe joints at the frame structure joints of prefabricated components, grouting material for post-tensioned prefabricated components, structural members for backfilling joints, and grouting material for rock foundations.
5. Non-shrink grouting between the foot screw machine base of the machinery and equipment and the concrete foundation.
6. Lining protective mortar for zinc-coated steel pipes.
7. Cement products including self-compacting prestressed, pre-stressed with steel sleeves, concrete and reinforced concrete drainage pipes, floor beams, columns, waterproof roof panels, etc.
8. Key structures requiring excellent crack resistance and perfect appearance, such as sports stands, museums, hotels, etc.
9. Highway road surface, bridge concrete deck, culverts, etc.
10. Construct high-strength, high-impermeable vertical well dam backfill slots filled with concrete.
This product is suitable for concrete engineering and cement products requiring crack and seepage-resistant joint filling.
