What is Refractory Cement (Fireproof Cement)?

Refractory cement /fireproof cement /fire cement contains high alumina content and other properties  that make it gain thermodynamic properties suitable for high temperature conditions. The fire cements are made with minerals like aluminium oxide to bind the coarse aggregates in the cement thereby increasing the thermodynamic properties of the cement, making temperature resistant and good formability. 

Castable refractory cement has chemical and physical properties used for creating heat-resistant structures that retain and insulate. Due to their high resistance to heat and thermal shock, you can use castable refractory cement and other products to build kilns and furnaces. Refractory castables can be used to create the monolithic linings within all types of furnaces and kilns.

Applications of Fireproof Cement in Kenya

The application of refractory cement in Kenya include: 

  • Incinerator walls, fences, 
  • Barbecues, fire drill areas, pizza ovens and other Industrial ovens 
  • Sewage and wastewater systems, 
  • Seaside projects, industrial floors, 
  • Agricultural buildings, lintels, sealing hinges
  • Blast furnace, Foundries, Forge furnace, Tunnel kilns, 
  • Heat treatment furnace car tops, Electro-phosphorus furnace, Sock pit cover construction etc.

Types of Refractory Cements (fireproof Cement) in Kenya

There are various types of refractory cement in Kenya. Kingsman Eng. And Industrial Insulation supplies the 3 main types refractory cement in Kenya.  These are Fondu Cement, Maxheat K and Maxheat A. The three types of cement are classified according to their alumina content which determines the range of temperature which they can withstand.

1. Maxheat K -1600°C (60%-Alumina)

One of the most common refractory cement (fire cement) in Kenya is Maxheat K.  It is premixed refractory compositions which can cast into any require shape and size. It is mostly preferred due to its high thermal and shock resistance.

MaxHeat K Specifications

  • Material: – Refractory Castable
  • Type: – 56% Min – 60% Max Alumina Dense castable
  • Nature of Bond: – Hydraulic
  • Installation: – Vibration Casting
  • Service Temperature: – 1600°C
  • Maximum Grain Size: – 5 mm
  • Water required for casting: – 11 to 12.5%

Applications of Maxheat K

Maxheat K fire cement in Kenya is applicable in General purpose uses, Blast furnace, Foundries, Forge furnace, Tunnel kilns, Heat treatment furnace car tops, Electro phosphorus furnace, Sock pit cover construction etc.

2. Maxheat A - 1750°C

Maxheat A is a castable cement in kenya suitable for high temperature applications. Just like Maxheat K It is premixed refractory compositions which can cast into any require shape and size. It is mostly preferred due to its high thermal and shock resistance.

MaxHeat A Specifications

  • Material: – Refractory Castable
  • Type: – 88% Min – 90% Max Alumina Dense castable
  • Nature of Bond: – Hydraulic
  • Installation: – Vibration Casting
  • Service Temperature: – 1750°C
  • Maximum Grain Size: – 5 mm
  • Water required for casting: – 9 to 11%

Applications of Maxheat K

Just like Maxheat K fire cement in Kenya, Maxheat A is applicable in General purpose uses, Blast furnace, Foundries, Forge furnace, Tunnel kilns, Heat treatment furnace car tops, Electro phosphorus furnace, Sock pit cover construction etc. However, its service temperature is higher than that of Maxheat K.

3. Max-50 (Fondu Cement)

CIMENT FONDU® is a calcium aluminate-based hydraulic binder and contains calcium silicates, as opposed to Portland Cements. Its has the properties of high early strength and good refractoriness.

Fondu Cement Properties

  • High temperature resistance (up to 1000°C)
  • Has 3 to 30 minutes setting
  • Corrosion Resistance (pH ≥ 4)
  • Suitable in very temperatures (-10°C)
  • Quick activity resumption (activities can be resumed after 6 hours

Fondu Cement Applications

Fondu cement in Kenya is applied in varios places such as incinerator walls, fences, barbecues fire drill areas, sewage and wastewater systems, seaside projects, ovens, industrial floors, agricultural buildings, lintels, sealing hinges etc.

Refractory castables are premixed combinations of refractory aggregates, matrix components or modifiers, bonding agents, and admixtures. They are mixed with a liquid (usually water) at the point of installation and vibrated, poured, pumped, or pneumatically shot into place to form a refractory shape or structure that becomes rigid because of hydraulic or chemical setting.

The majority of refractory castables use calcium aluminate cement as the bonding agent though in recent years other bonding agents have also been developed. All castables have refractory aggregates and matrix components which allow their use to temperatures up to 1850 deg C.

  1. CONVENTIONAL DENSE REFRACTORIES

Conventional dense castables are created with high alumina cement, and can withstand temperatures from 1300oC to 1800oC. These refractory castables are great for common furnace applications, burner blocks, speciality muffle furnaces and boiler work. Resistance is a key quality that varies with the choice of materials, resulting in abrasion, thermal shock and slag attack. Casting and gunning techniques are the method of installing the materials. For the ease of castable placement, gunning materials and water are combined together at the gunning equipment’s nozzle. This is a great method of placement for bulk materials, in cases when circumstances make formwork overly time consuming or simply impractical. In general, the method of installation will depend on cost and accessibility.

  1. INSULATING 

Another product that we supply is the castable refractories that are low density. These insulating castables pose very low thermal conductivity and are utilized for either high temperature face work or when used for a backup lining, which is found behind dense castables or brick work. Here, the insulating castables are able to decrease the lining’s overall density or the cold face temperature. Their strength, which ranges from low to medium, is based on the fact that their density is low and is the main reason that they are not resistant to abrasion. They are most suitable where they do not have to stand up to much wear and tear.

  1. LOW CEMENT

This type of refractory castable is prepared with a lower amount of cement than the standard dense castable is normally created with. Low cement castable refractories fluctuate in alumina content, which provides exceptional physical properties, including low porosity, great abrasion properties and high vigour. These products will commonly necessitate installation that is controlled, however, the big advantage of low cement castables is that they are easily pumped into position, and some may not require vibration, because they are free flowing.
