What is Refractory Cement Mortar and what are its Uses?
Refractory Cement Mortar is a type of binding material that sets hard and becomes resistant to heat, chemical corrosion or erosion. They are used in many refractories such as molds for metal casting, kilns & furnaces. In the construction industry it can be used on fireplaces, hearths and stoves.
Refractory Cement Mortars are usually made from a mixture of cement, binder and water; they can also be combined with other materials such as fly ash or silica fume. The addition of these fillers makes the product more durable and resistant to heat & chemicals. However, it does make them harder for building applications requiring easy shaping like fireplaces or flue linings. It is recommended that you use refractory mortar for this type of job instead.
Why use Refractory Cement Mortar for your Project?
Refractory Cement Mortar is a mortar or clay-like material used for construction and repair of kilns, furnaces and fireboxes. It is also known as refactory cement because it has the ability to turn into glass when subjected to heat. When mixed with water, this cement hardens quickly due to its quick drying quality which makes it an ideal choice for temporary repairs such as patching up cracks on brick surfaces before making more permanent renovations. Refractory Cement Mortars are often used in high temperature industrial applications such as chemical plants, steel mills and power stations where they serve not only structural but functional purposes like insulating components against extreme temperatures.
There are two types of Refractory Cement Mortars – lightweight and high-temperature. Their composition varies depending on the type of application they will be used for, so it is important to consider this when choosing materials.
High-temperature cement can withstand temperatures as high as 2300 degrees Celsius (about 4000 degrees Fahrenheit) which makes them perfect for repairing furnaces or lining fireboxes where furnace repair costs may otherwise turn out too expensive. These types usually contain enough alumina content that allows them to contract at a slower rate than clay, thus avoiding heating up or cracking due to uneven contraction rates between inner walls and outer surfaces during cooling down processes. High temperature refractoriness also helps insulate these components by creating an atmosphere around them that is more oxygen-free.
Lightweight Refractory Cement Mortar, on the other hand, has a lower temperature resistance of about 1200 degrees Celsius (about 2100 degrees Fahrenheit) and serves mainly structural purposes such as strengthening foundations or repairing masonry surfaces in kilns and furnaces. They do not contain alumina which makes them less insulating but they are also less dense so they can be used to fill up empty spaces caused by shifting bricks – making them an ideal choice for temporary repairs where there is no need to preserve heat insulation properties like when patching already broken brickwork before major renovations.
Types of Refractory Cement Mortar
There are many types of Refractory Cement Mortar, with special properties and applications. These include:
- Magnesium oxide (MgO) is used in high-temperature applications; it has an extremely low thermal conductivity at elevated temperatures due to the flow of electrons through the material. It can be formed into different shapes for its application depending on how much magnesium oxide is added to the mixture. MgO should not come into contact with water or carbon dioxide because they will react with each other causing violent exothermic reactions that may lead to fire explosions.
- Phosphate bonded – This type binds together using phosphoric acid which occurs naturally in teeth enamel, bones, eggshells and pearls . It is especially good for insulation, because it does not release any toxic fumes when heated to the point of ignition.
- Binder-Calcium aluminate cement – This type has a low expansion rate at high temperature, giving resistance to thermal shock in refractory work. It also allows easy machining during installation and provides an economical choice where moderate heat is required.
- Molybdenum disilicide – This type has a high thermal conductivity at elevated temperatures, making it useful for heat exchangers. It is often used in the form of tiles because they are easily machined to fit the contours of structures. When mixed with other materials, silicon carbide or alumina can also be applied as coatings.
- Binder-Silicon carbide cement – This type has low thermal conductivity at elevated temperatures, making it very suitable for high temperature insulation. It is often used in the form of tiles because they are easily machined to fit the contours of structures. When mixed with other materials, silicon carbide or alumina can also be applied as coatings.
How to choose the best Refractory Cement Mortar for your job
When choosing between different kinds of Refractory Cement Mortars, one must take into consideration the chemical composition. A variety of cement types are available that vary in their ingredients and working properties. After determining how much insulation is needed for your job, you can apply this information to choose which type of Cement will work best for your needs.
Refractory Cement Mortar is often made from very high temperature resistant materials. These are used to patch holes in furnaces, repair places where brick has broken or even build entirely new ovens and kilns. The chemical makeup of the Refractory Cement Mortars determines how much heat it can absorb before being damaged. In general, they begin to break down when exposed to temperatures just above 1550 Celsius (2822 Fahrenheit). However, their ability rapidly decreases as the temperature increases. For example, a common type of furnace cement breaks down at 1713 Celsius (3073 Fahrenheit), while an Alumina-Silica type will last until 1832 Celcius (3300Fahrenheit) before melting away completely.
- Ceramic cement is a type of Refractory Cement Mortars that are made up mostly or completely from ceramic materials. They are the strongest and most heat resistant, but also much more expensive than other types.
- Another common type is Fireclay Cement which contains clay combined with calcium aluminate binder to form an exceptionally hard material used for high-temperature insulation. It has good resistance to chemical attack by molten metal at all casting temperatures between.
- Refractory Mortar can be easily mixed in small batches due to its quick drying time. However it isn’t suitable above 1900 Celcius (3724 Fahrenheit).
- It should be noted that there are many different grades within each category listed above, so just because you have chosen one type doesn’t mean that it will be a perfect fit for your project. You should research each to determine which one is the best possible match.
Common Mistakes when using Refractory Cement Mortars
- Do not use more than the recommended amount of water. Though Refractory Cement Mortars are typically very dry and will absorb a lot of moisture, it is important to stick with what has been recommended by the manufacturer in order for your cement mixture to be successful.
- It’s also best practice when using any type of refractory insulation or coating to ensure that you work on a surface that can withstand high temperatures without sustaining damage (such as steel). If you need something safer, try working on an asphalt slab since it won’t burn even if exposed directly to flames. However, this isn’t ideal because asphalt is extremely cold which means less heat retention for curing times.
- Do not use a concrete mixer unless you have been directed to do so. Concrete mixers will help blend the ingredients together, but too much stirring can cause damage to Refractory Cement Mortar’s integrity and its ability to withstand high temperatures. It is best practice when using any type of refractory insulation or coating to ensure that you work on a surface that can withstand high temperatures without sustaining damage (such as steel). If you need something safer, try working on an asphalt slab since it won’t burn even if exposed directly to flames. However, this isn’t ideal because asphalt is extremely cold which means less heat retention for curing times.
Refractory Cement Mortars are environmentally friendly. They do not contain any harmful chemicals like asbestos, which was used in traditional refractories and has been linked to some serious health issues. There is also less waste when using the product because it can be reused for several applications without fear of negative impact on the environment or human health.
- Always wear a mask and gloves while working with Refractory Cement Mortar.
- If you get any on your skin, wash it off immediately.
- Refractory Cement Mortar is “like a glue”, so it doesn’t easily come off.
- If it does get on your skin, you should wash the area immediately with cool water.
