Refractory Mortar Pre Mixed 15KG
Refractory mortar, also known as firebrick mortar, is a specialized type of mortar designed for use in high-temperature applications such as wood fire ovens, bbqs, fireplaces, furnaces, and other heat-resistant structures. Here's more information about refractory mortar:
1. Composition: Refractory mortar is formulated with high-temperature-resistant materials such as calcium aluminate cement, fireclay, silica sand, and other additives. These ingredients are carefully selected to provide excellent heat resistance, bonding strength, and durability.
2. Heat Resistance: Our refractory mortar is capable of withstanding extreme temperatures up to 1,300°C. It remains stable and structurally sound even when exposed to intense heat, making it suitable for use in fireboxes and other high-temperature environments. Our refractory mortar is pre-mixed and a air-set mortar which requires air to set after the application.
3. Bonding Strength: Refractory mortar forms strong bonds between firebricks, providing structural integrity and preventing the disintegration of the masonry assembly under thermal stress. It ensures tight joints and seals between the bricks, minimizing heat loss and gas leakage. The ideal joint is 3-5mm between the bricks.
4. Expansion Properties: Refractory mortar is designed to accommodate thermal expansion and contraction of the masonry assembly during heating and cooling cycles. It maintains flexibility and elasticity, preventing cracks and gaps from forming in the mortar joints.
5. Chemical Resistance: Refractory mortar is resistant to chemical degradation from exposure to acids, alkalis, and other corrosive substances commonly encountered in high-temperature environments. It retains its bonding strength and structural integrity over time, even in harsh domestic or industrial settings.
6. Application: Refractory mortar is typically applied between firebricks or refractory bricks to bond them together and form a tight seal. It can also be used to repair damaged masonry joints or to fill gaps and voids in refractory materials.
7. Curing Process: Refractory mortar requires a curing process to achieve optimal strength and heat resistance. This typically involves allowing the mortar to air dry for a certain period and then gradually exposing it to increasing temperatures to drive off moisture and activate the cementitious properties.
Overall, refractory mortar plays a critical role in the construction and maintenance of high-temperature structures, providing strong, durable bonds between firebricks and ensuring the integrity and longevity of the masonry assembly.
Our mortar it comes in 15kg buckets in powder condition and it contains 1mm aggregates(smashed fire bricks) to ensure its strength and elasticity.
