Properties and Effects of Super Micro‑Silica Gel ZG100

Using Super Micro‑Silica Gel ZG100 produces a remarkable improvement in concrete performance. Due to its unique chemical structure and active ingredients, this gel has outstanding effects on the quality, performance, and service life of concrete.

Increased Compressive Strength

One of the most significant benefits of ZG100 is its ability to increase the compressive strength of concrete by 20–30% compared to standard mixes. Nano‑sized microsilica particles fill voids between cement grains, creating a denser structure that improves aggregate bonding and enhances the final strength of concrete.
Reduced Permeability

ZG100 drastically reduces concrete permeability against water and harmful ions such as chlorides and sulfates. This is especially crucial for structures exposed to moisture or chemicals, including dams, tunnels, wastewater plants, and coastal structures.
Enhanced Durability and Service Life

By increasing density, reducing capillary pores, and controlling cracking, ZG100 concrete structures achieve significantly higher durability and longevity, resulting in lower maintenance costs over the structure’s lifespan.

Applications of Super Micro‑Silica Gel ZG100

Mass Concrete Structures

Controls hydration heat in large concrete pours such as industrial foundations, dams, and bridge piers, preventing thermal cracking and sudden internal temperature drops.
Waterproofing Projects

Essential for waterproofing tanks, swimming pools, treatment plants, and marine structures. Works much like a waterstop by filling voids in concrete and preventing the ingress of water and corrosive agents.
Structures in Aggressive Environments

In oil, gas, petrochemical, and other corrosive settings, ZG100 boosts chemical resistance against sulfates, chlorides, and acidic environments.

Safety Guidelines for ZG100

In case of skin or eye contact, rinse thoroughly with water.
Wear gloves, safety goggles, and a mask during application.
Use only in well‑ventilated areas.

Storage Guidelines

Store in sealed containers, away from direct sunlight.
Keep between 5°C and 35°C.
Protect from freezing.

Transport Guidelines

Use secure, stable packaging during truck or forklift transportation.
In case of leakage, wash the affected area with water and transfer the material to its original container.

Dosage Recommendations

The exact dosage should be determined according to project requirements, concrete type, environmental conditions, and desired durability.

Recommended Dosage (kg/m³)	Structure Type
35–40	Standard structural concrete
45–50	Mass or waterproof concrete
50–55	Concrete in aggressive ionic exposure

Although the initial material cost increases slightly with ZG100, its ability to reduce permeability, enhance durability, and minimize repair needs makes it the most cost‑effective choice for long‑term infrastructure projects.

Physical and Chemical Properties of Super Micro‑Silica Gel ZG100

This section presents the appearance, chemical structure, and general properties of ZG100 by ZORLU Chemical, enabling users to gain a precise understanding of the product.

Appearance and Color

ZG100 is supplied as a thick, homogeneous, dark gray gel. Its uniform texture and sediment‑free nature allow it to blend easily with other concrete components.

Specific Gravity

The specific gravity of this gel is approximately 1.35 to 1.45 g/cm³, indicating a high concentration and density of its materials.

pH and Solid Content

pH: Approximately 6 to 8, providing a relatively neutral environment that does not harm the concrete.
Solid Content: Between 35% and 40%, which is higher than many similar products in the market, offering better performance.

Application Method for Super Micro‑Silica Gel ZG100

The correct application of Super Micro‑Silica Gel ZG100 has a direct impact on concrete performance and efficiency. To achieve the desired properties, it is essential to follow the usage instructions and mixing procedures for incorporating this gel into the concrete mix.

Concrete Preparation Steps

Before adding ZG100, ensure the quality of other concrete components such as cement, gravel, sand, and water. If other admixtures such as plasticizers or accelerators are being used, coordination with the quality control department is necessary.

Steps for Adding ZG100 to Concrete

Add aggregates, sand, and cement to the mixer.
Add ZG100 together with part of the mixing water to the batch, ensuring thorough blending with the other components.
Add the remaining required water to achieve the desired workability.
If needed, add a plasticizer or superplasticizer at the final stage.

Combination with Other Admixtures

ZG100 contains internal plasticizing agents, often reducing the need for additional plasticizers. However, for concrete mixes with a very low water‑to‑cement ratio, the simultaneous use of compatible superplasticizers is permissible. It is recommended to conduct compatibility testing before combined usage.
