Experimental Study on Mechanical Properties of Marine Sand and Seawater Concrete

As Chinese development of marine resources intensifies in recent years, more and more offshore platforms and buildings, island structures are under construction. However, concrete aggregate and freshwater resources which are used to mix concrete are usually limited in coastal areas or on the islands. This paper concentrates on marine sand and seawater concrete which use marine sand instead of river sand as concrete fine aggregate and mix with seawater instead of freshwater. Also mechanical properties including compressive strength, failure mode, elasticity modulus, relationship of stress-strain were compared and analyzed between marine sand and seawater concrete and ordinary concrete.
