Abstract
The development of residential areas in coastal areas of Indonesia is crucial for supporting communities and improving their well-being. One major challenge is the use of concrete that is resistant to aggressive environments, such as exposure to magnesium sulfate triggered by chloride content. This study aims to determine the effect of variations in silica fume, polycarboxylate superplasticizer, and quartz sand on concrete resistance to chloride attack. The concrete used had a design strength of 35 MPa with variations in silica fume proportions of 0%; 5%; 7.5% and 10% with the addition of 5% quartz sand, and 2% polycarboxylate superplasticizer. Compressive strength and permeability tests were conducted on cylindrical specimens with a diameter of 10 cm and a height of 20 cm, after 28 days of immersion and curing in a chloride solution. The concrete mix design used the SNI 03-2834-2000 method. The results showed that the addition of silica fume, polycarboxylate superplasticizer, and quartz sand increased concrete compressive strength and reduced concrete permeability when substituting 10% silica fume for concrete. This combination of admixtures was effective in increasing concrete's resistance to chloride attack in aggressive coastal and marine environments. This study recommends the use of silica fume and quartz sand as admixtures to improve concrete performance in coastal areas.
