Micro‑Silica Gel TT100

Building waterproofing materials

سطل ۲۵ کیلویی

Micro‑Silica Gel TT100 is an advanced additive based on polycarboxylate ether, incorporating a modified and enhanced formulation of micro‑silica, polycarboxylate superplasticizer, water‑repellent agents, and polypropylene fibers.

With its special formulation, this product ranks among the most effective building waterproofing materials, delivering substantial improvements to concrete performance, including:

Increased compressive strength
Reduced permeability to water and aggressive agents
Extended durability of reinforced concrete structures

By combining the right proportion of pozzolanic materials and superplasticizers, TT100 not only offers easy application but also plays a critical role in strengthening various structures, particularly in corrosive environments and under harsh climatic conditions.

It is recommended to use superplasticizer NR100 alongside this product to achieve better workability.

Safety Guidelines for Micro‑Silica Gel TT100

Wear protective gloves, safety goggles, and a suitable mask to avoid skin and eye contact.
In case of skin contact, wash thoroughly with soap and water.
In case of eye contact, rinse immediately with plenty of water and seek medical advice.
Avoid inhaling vapors or accidental airborne particles, especially in confined spaces.
Do not eat, drink, or smoke while handling the gel.
Keep out of reach of children.

Storage Guidelines for Micro‑Silica Gel TT100

Keep in its original sealed container, away from excessive moisture and direct sunlight.
Recommended storage temperature: 5 – 35 °C.
Prevent freezing or excessive heat exposure.
Always reseal after use to avoid drying or contamination.
Recommended shelf life: 12 months from production when stored properly.
Keep away from acids or reactive chemicals.

Dosage of Micro‑Silica Gel TT100

Standard dosage: 6 – 12% of the cement weight in the concrete mix.
The exact amount should be determined based on project conditions, raw materials, climate, and cement type.
Project engineers should adjust the dosage after technical evaluation and lab testing.
For high‑strength concrete and improved mechanical properties, it is recommended to reduce the mix water by 10 – 15% before adding TT100 to lower the water‑cement ratio, enhance cohesion, and prevent shrinkage or surface cracking.
Optimal dosage should always be confirmed by laboratory trials using project‑specific materials.

Method of Use for Micro‑Silica Gel TT100

The application method of Micro‑Silica Gel TT100 depends on project conditions and the concrete production process. In general, it can be introduced into the concrete in two main ways:

Mixing with part or all of the mixing water:
- Combine Micro‑Silica Gel with all or part of the concrete’s mixing water.
- Add this mixture to the dry materials.
- Mix thoroughly to ensure all components are fully blended.
Direct addition to the fresh concrete mix:
- Add the gel directly after all other concrete components have been loaded into the mixer.
- Continue mixing to achieve full dispersion.

Key Mixing Guidelines

In both methods, ensure at least 1 minute of mixing per cubic meter of concrete to achieve uniform distribution of the gel within the mix.
If there is a significant time gap between batching and placement (common in large‑scale projects), it is recommended to add the gel in two stages:
- Add half of the dosage during initial batching.
- Add the remaining half about five minutes before pouring, directly into the truck mixer.
After each gel addition, mix the concrete for 2–4 minutes to ensure complete and uniform dispersion.

Following these steps helps maximize the performance benefits of Micro‑Silica Gel TT100 and ensures the desired improvements to concrete properties.
