DO YOU HAVE CRACKS IN YOUR BARBECUE?
TEIDE REFRACTORY SOLUTIONS with more than 65 years of experience in the refractories world, is highly specialized in the construction of structures that must withstand high temperatures and thermal shocks.
Problems in the assembly of your barbecue?
When assembling a barbecue the typical problem of cracking can arise, this cracking is due to a bad application of the mortar as well as in the arrangement of the bricks.
Cause and solutions for barbecue cracking
Thickness of mortar joints: Mortar joints between bricks should be between 10-15 mm thick. This measure is recommended by the bibliography and our own experience.
Absence of expansion joints: This absence of joints causes that the dilatations of the refractory itself when heated generate irreversible deformations causing cracks in the brick. The design of joints can be very varied and can be decided to fit the design of the barbecue.
Bracing of the structure: This metallic structure covers the barbecue and helps to reduce the expansion of the whole structure, thus preventing cracks.
The image shows the arrangement of the bricks and the recommended joint thickness for high temperature applications.
TEIDE REFRACTORY SOLUTIONS recommends:
Use mortar thicknesses between 10-15 mm, greater thicknesses lead to a greater volumetric variation of the mortar, thus generating a greater divergence in the coefficients of expansion between the brick and the mortar, which results in cracks.
Design the barbecue with expansion joints to avoid the generation of cracks due to the action of expansion and contraction of the refractory material.
It is better to design a barbecue with a confining structure, it can be made with metallic structures.
