It's no secret that FLORIDA CRUSHED STONE--consisting of one plant in Brooksville, Fla.--is looking for a new owner. Right now, the companies that are looking a little more closely than most include Florida Rock Industries, Lafarge, and CSR Rinker Materials, all of which have an eye to expand their presence in the Southeast. Also considered in the running are RMC and the Portuguese giant, Cimpor Group, which use this buy as a way to enter the U.S. market.
