What does the raw material combination of వక్రీభవన ఇటుకలు అర్థం?

The combination of refractory brick raw materials refers to the combination of clay raw materials and non-plastic raw materials to form plastic clay clusters and have a certain dry strength. The bonding ability of bonding clay is usually reflected by the amount of standard quartz sand (70% is 0.25～0.15mm, 30% is 0.15～0.09mm) and the flexural strength after drying when the plastic clay body is formed. Clay with strong plasticity has strong bonding ability.
