Greek cement firm Titan’s  U.S. unit signed an agreement to buy Virginia-based ready-mix concrete firm Powhatan as part of its expansion plans, it said in a statement on Wednesday.  
 
Titan America LLC is expected to complete the purchase of Powhatan, which operates five plants, in May, the company said. The purchase is Titan’s third in as many weeks. 
 
Titan already operates a cement plant in Roanoke, Virginia, a cement import terminal in Norfolk, as well as other ready-mix concrete plants and fly ash processing businesses in the U.S
