Description
Summary:The main objective of this research is to study the effect of the chemical composition and grain size of pit sand on the permeability of concrete. The sand was taken from three locations in the Merauke area, which is located in Papua Province, Indonesia. To test the permeability of concrete, an equivalent method was employed that measured the depth of water penetration in the concrete. The results of this study indicate that the grain size and chemical properties of the sand affect concrete permeability. The weight percentage of sand grains larger than 2.36 mm is found to be proportional to the permeability of the concrete. The greater the percentage of gravel, the greater the depth of water penetration. In contrast, concrete permeability is found to be inversely proportional to the percentage of fine sand, which is sand with a grain size of less than 0.5 mm. In addition, two chemical compounds are found to affect the permeability of concrete, namely calcium oxide (CaO) and aluminium oxide (Al2O3).
