Abstract
Abstract. Infrastructure development in Indonesia mostly uses concrete as a construction material. The eruption of Mount Marapi in West Sumatra which occurred on December 3, 2023, spewed material in the form of sand and volcanic rocks. Mount Marapi volcanic sand is sand obtained from nature and has different qualities that affect the strength of the concrete. This study aims to obtain the properties of concrete-forming materials by using volcanic sand as a fine aggregate in the laboratory and compare the results of concrete compressive strength using volcanic sand and tidal sand. The method used in this study is experimental. A cube-shaped concrete sample measuring 15 cm x 15 cm x 15 cm was made with a variety of concrete using volcanic sand from Mount Marapi and tidal sand. The concrete was then tested for compressive strength at 28 days. The results showed that concrete with a mixture of volcanic sand provided a higher compressive strength of 23,662 Mpa compared to concrete with tidal sand of 20,876 Mpa. Keywords: concrete, compressive strength, volcanic sand
