Karakteristik Beton Kerang Silica fume dalam Larutan NaCl dengan Metode Wetting-Drying

ABSTRACT
Concrete in a seawater environment is prone to damage due to the high salt content in seawater. Seawater intrusion causes salt crystallization in concrete pores. tidal conditions resulting in wet-dry cycles on the structure accelerate the crystallization process. Therefore, the characteristics of concrete will be studied using shell powder and silica fume as a substitute for cement to strengthen concrete in seawater environments. Shellfish shells powder can be used as a substitute for cement because they contain high CaO, like cement. In this research the concrete uses seashell powder as a partial replacement for cement with variations of 0%, 5%, and 10% and Silica fume as an added ingredient with an amount of 5%. Samples used cylindrical concrete with variations in immersion age of 0 days, 28 days, and 56 days. To determine the impact of tides, immersion was carried out using the static method and the wetting-drying method. The test parameter is to determine the value of compressive strength, porosity, sorptivity, and density or UPV. From the research conducted, the compressive strength value in static immersion has the highest compressive strength value in the third variation, or 90% PCC + 10% BK + 5% SF, which is 37.05 MPa at 28 days of immersion. In the wet-dry immersion, the highest compressive strength was also found in the third variation with a 28-day immersion age of 28.58 Mpa. Overall, the third variation has the lowest porosity, lower sorptivity and better density or UPV than the other variations. The addition of 10% shell powder increased the quality of concrete after 28 days of immersion in NaCl solution, but the quality decreased after 56 days of immersion. This is due to the continuous intrusion of sea water which exacerbates the damage caused by salt crystallization in the pores of the concrete.
