20, ABSTRACT (ConHnue on reverse side II necessary and idenlily by black number) 



A lightweight concrete specially suited for deep ocean applications was tested for its 

 strength properties and compared to similar regular lightweight concrete. The new concrete 

 used lightweight aggregate particles (expanded shale) which were filled with a polymeric 

 material. The polymer-filled aggregate (PFA) was conventionally mixed with portland cement 

 and water to make the lightweight concrete. Four concrete mixes were tested. In general, 

 the PFA concrete, compared to regular lightweight concrete, has an equal unit weight in a
