One of them is shells, shellfish waste or shells are usually only used as decorations or toys so that there is still a lot of waste wasted. Inside the shell, the clam contains pozzolan chemical compounds, namely lime (CaO), aluminum oxide and silica. It can be expected to improve the quality of concrete.
 As a result of compressive strength test by changing the clamshell to 0%, 10%, 20%, 30%, 40% and 50%, the average compressive strength value of 0% (ordinary concrete) was 15.81 MPa. The addition of a 10% clam shell results in an average compressive strength value of 20.58 MPa. For the addition of clam shells by 20% obtained an average compressive strength value of 23.37 MPa. 30% yields an average compressive strength of 40.31 Mpa, to 40% of 29.12 Mpa. As for the addition of 50% clam shells, the average compressive strength value is 24.79 Mpa.

 The performance and durability of concrete in construction is essential to maintain the sustainability and protection of the material. Particularly in construction in marine environments, the attack of aggressive chemical compounds can affect concrete and accelerate deterioration. This research aims to improve the performance and durability of concrete in construction in marine environments by using additional protection methods such as Surface Applied Protection. One of the materials used is geopolymer mortar that uses fly ash as a base material. This study shows that geopolymer mortar contributes positively to the compressive strength and durability of concrete. The thickness of the geopolymer mortar layer affected the mechanical properties of the concrete, and 4 cm thick gave the highest compressive strength results. The addition of geopolymer mortar needs to be adjusted to the compressive strength of the concrete and pay attention to the layer thickness for optimal results.
