Sweeling agent

 

TS-069E (03/06) Swelling agent is mixed by limestone powder, clay powder, alumina powder and iron oxide powder, and calcined at high temperature to form calcium oxide, silicon.Calcium acid and calcium sulphoaluminate are supplemental powder materials. The product has large expansion rate and high strength, and it is the only plastic expansion and rigid expansion on the market.

Expanded product. After 3 days of curing, it was transferred to dry air. The 60-day expansion rate was still 30-50%, and the structure did not show absolute shrinkage. After the basement is backfilled,

The concrete is re-obtained and the expansion rate can be restored to 95% of the large value, and the micro cracks are self-healing. Anti-cracking effect is very obvious, suitable for underground self-defense

The water concrete structure can eliminate external waterproofing and extend the seamless construction of the structure. Maintenance conditions are greatly reduced, simplifying the construction process and reducing construction costs. Also suitable for tunnels, water plant pool concrete crack resistance.

 

 

Scope of application:

Generally, it is necessary to compensate for the occurrence of dry shrinkage of cement mortar, such as waterproof concrete for civil building basement; road and railway waterproof concrete;

Political sewage pools, clean water pools, anti-mixed soil, etc.
