The Effect of Iron Sand (Wale) On The Compressive Strength of Quality ConcreteF'c 26.4 Mpa

Concrete is the most widely used building material in construction, both building and bridge construction. This is supported by the ease of the concrete making process that can be made by various groups, both those who understand concrete mix design and those who have no understanding of concrete at all. The difference between the two is only in the quality and quality of the concrete made. The effect of iron sand on normal concrete constituent materials is carried out using percentages of 0.5%, 5% and 20% of the total volume of natural sand used. In this study, iron sand additives were used to determine the most optimal percentage that affects the compressive strength of concrete with the addition of iron sand material of 0.5%, 5% and 20% of the total volume of natural sand. The review of the analysis of this study is compressive strength with a cylindrical test piece with a diameter of 15 cm and a height of 30 cm. From this study, it can be known that the strength of the concrete produced by the use of iron sand mixture is 0.5%, 5% and 20% of the total volume of natural sand.
