You can be sure that TXI ES&C lightweight aggregate will hold up
under extreme fire temperatures and enable the masonry to protect fire
fighters, occupants, and property. After all, it has been mined from the
earth itself and fired in rotary kilns at temperatures exceeding
2000°F (1000C). There is nothing left to burn in our aggregate
– no “loss on ignition” (LOI) that could occur in
other types of lightweight aggregates. Recovered from structural grade
ES&C manufacturing processes, you can feel safe and secure with
masonry utilizing TXI ES&C as its primary aggregate constituent.
