Castables | Raw materials with excellent chemical resistance

HASLE castables are manufactured on the basis of our own unique recipes

Even though our recipes are considered being among the best in the world, we continuously invest in R&D and plant equipment and we have excellent references.

Why you should chose HASLE Castables:

Premium Quality raw materials - proven recipes. In dept Quality Assurance based on ISO 9001:2015
› Flexible Production Plant located in Denmark - provides fast responsetime on orders of all sizes

› Gunning castables with very low rebound - reduces waste in the installation process
Insulating castables completes your HASLE Refractory solutions. 

Our castables:
Traditional | Low-cement Gunning Insulating plus Mortars are manufactured in our highly automated plant and internal procedures ensure that we deliver a consistent, high quality. A detailed quality system secures that all castables leaving our factory comply with our high requirements on particle-size distribution, castability and physical properties.

In order to make the best quality of materials, we source only the very best raw materials - no recycled materials and no prefabs from other suppliers. At HASLE we are sourcing our raw materials from suppliers in 14 different countries all over the world. We are in no way depending on using local or domestic raw materials. We are free to choose the very best raw materials, and we do so.

Type Characteristics


Traditional castables are composed of relatively few and well-known components. They are available with a wide range of properties allowing use for not too demanding jobs where mechanical and chemical action on the castable is low.



HASLE LCC's (dense castables) are developed to achieve the best combination of mechanical strength and resistance to impact and alkaline corrosion at high temperature.

The LCC castables are characterised by a very low porosity which reduces the risk of slag attack and corrosion. Consequently the low-cement castables are highly resistant to alkaline attacks from e.g. sodium and potassium salts – compounds that are often occurring in bio-fuels, waste etc.

This means a lining with long lifetime and high durability, and on a long view LCC will be a more economical choice than the traditional castables.

Non-cement (NC) 

HASLE NC's are based on the same high quality raw materials as the LCC products, but uses a silica gel bonding system to include extra fast and simple dry-out to the installation options when using HASLE products. Further to this the silica gel bonds are less vulnerable to alkali- and thermal attack than cements bonds, improving HASLE NC performance at elevated temperatures.  


The gunning castables are gunned onto walls and ceilings with minimal waste.  The rebound is extremely low and second to none. Gunning castables distinguish themselves by their very quick application time. To learn about gunning, please click our test Videos GUN 59A and GUN39A.


Insulating castables differ from other castables either by the main component of the castable, the grog, consisting of components with very high porosity, or by these components forming very porous structures by heating.

From an application point of view insulating castables are competing with insulating (porous) bricks. An insulating castable is suited as filling material between e.g. a high refractory lining and block insulation. The insulating castable flows into all corners and cracks and leaves no cavities. Besides it is easy and uncomplicated to handle.
Mortars were developed to bind bricks together in bricked linings. Refractory mortars are made from fire clay and refractory clay/cement where the particle size has been adapted for the desired application.
