Abstract
A structural grade lightweight concrete that is especially suited for ocean pplications. The lightweight concrete uses regular lightweight aggregate particles that have been modified by filling the voids within the particles with a polymeric material. The polymer-filled aggregate particles are then bonded together using a cementitious or binder material to form concrete. Typically Portland cement is used as the binder to produce a lightweight concrete for construction of ocean structures.
