Boiler Sand

Boiler sand is formed in dry firing boilers of modern power stations during the combustion of the mineral rocks entrained in hard coal. Alumino-silicates, which basically also form the crust of the earth, are the main constituents of the porous boiler sand.


• Low installation weight at high volume
• Good processing capability
• Environmental compatibility
• Cost-effectiveness

Areas of application

• Ground fillings
• Working area backfilling
• Soil improvement
• Cable sand
• Dyke piling
• Noise protection embankments

Through the employment of boiler sand, natural resources can be protected and energy saved for the production of comparable building materials.
