Silicate Mortar

About Silicate Mortar

BHAVANI REFRACTORY-Silicate mortar, also known as potassium silicate mortar or potassium water glass mortar, is a type of inorganic mortar used for various construction and industrial applications. It is composed of potassium silicate solution (potassium water glass) mixed with a filler material such as silica sand or other aggregates. When the mortar cures, the potassium silicate solution undergoes a chemical reaction with carbon dioxide in the air, forming a hard, durable, and chemically resistant bond.

Here are some key characteristics and applications of silicate mortar:

Chemical Resistance: Silicate mortar offers excellent resistance to a wide range of acids, alkalis, salts, and other chemicals. This makes it suitable for use in environments where corrosive substances are present, such as chemical processing plants, wastewater treatment facilities, and laboratories.

Temperature Resistance: Silicate mortar can withstand high temperatures, typically up to around 400C (752F) depending on the specific formulation. This makes it suitable for applications where elevated temperatures are encountered, such as in industrial furnaces, kilns, and chimneys.

Inorganic Composition: Silicate mortar is an inorganic material, meaning it does not contain organic components that can degrade when exposed to heat or chemicals. This results in a highly stable and durable mortar that is resistant to degradation over time.

Adhesion: Silicate mortar forms strong bonds with various substrates, including concrete, brick, stone, and metal. This ensures good adhesion and structural integrity of the bonded surfaces.

Low Shrinkage: Silicate mortar typically exhibits low shrinkage during curing, which helps to minimize the risk of cracking and ensures a tight seal between bonded surfaces.

Applications: Silicate mortar is commonly used for various construction and repair applications, including masonry, concrete repair, joint sealing, and bonding of refractory materials. It is particularly well-suited for use in acid-resistant linings, flooring, and coatings in industrial environments.

Environmentally Friendly: Silicate mortar is considered environmentally friendly because it is composed primarily of inorganic materials and does not release volatile organic compounds (VOCs) during curing. This makes it a preferred choice for green building projects and sustainable construction practices.

Overall, silicate mortar is valued for its excellent chemical resistance, temperature stability, durability, and environmentally friendly properties. It is a versatile material used in a wide range of industrial and construction applications where resistance to corrosion, chemicals, and high temperatures is required.

High Acid Resistance for Demanding Environments

This silicate-based mortar boasts excellent resistance to most inorganic acids, excluding hydrofluoric acid. Its durability and chemical stability make it suitable for use in aggressive industrial environments, including chemical plants, acid plants, and pharmaceutical facilities. By providing strong acid resistance, the mortar helps extend the lifespan of linings and structures exposed to harsh chemicals.


Rapid Setting and Superior Strength

With an initial setting time of 4-6 hours and final curing in 24 hours, Silicate Mortar ensures a swift project turnaround without compromising structural integrity. Its high compressive strength (10-12 N/mm2) and low water absorption allow for robust applications in joining acid-resistant bricks and tiles, providing reliable, long-lasting bonds in both new construction and repairs.


User-Friendly Mixing and Application

The two-component system, comprising powder and liquid, is easy to mix following manufacturer guidelines (typical ratio of 3:1 by weight). The ready-to-mix formulation and detailed instructions ensure precise, efficient installation for floors, linings, and other industrial applications. The smooth surface finish and dimensional stability simplify handling, minimizing installation errors.
