Recon Engineering & Construction has been having fun blasting out refractory cement from the inside of the preheater tower at this cement plant. Once it’s all cleaned out they’ll do steel repairs, weld in anchors where the old ones have failed (our S-Bar anchors can help with that issue) and then shoot new refractory cement. This is the best time to replace refractory-lined expansion joints because the refractory contractor can line the expansion joint at the same time as the ductwork, saving the plant money.
