Application of refractory castables

Vibrocasting application

This system of application consists in the preparation of forms in the area to be repaired and then pouring concrete dense, previously prepared using a planetary mixer, and vibrate it with an electric or pneumatic needle. This concrete has elevated density values, mechanical strength and resistance to abrasion and erosion, with less water requirements. The final aspect of the coated surface is completely smooth and free from wrinkles. Pouring can be done manually or mechanically by buckets, with a specific refractory concrete pump, mixing it with the appropriate percentage of water and pumps it through hoses to the point of use, allowing a reduction in execution times. 6 to 7 operators with planetary mixer, with refractory concrete pump 4 to 5 operators are required.
