ABSTRACT

Purpose: This Research to know whether the waste of iron sand and bottom ash can be used as substitute aggregate looks at the percentage of bottom ash and iron sand waste as fine aggregate for concrete production. The use of such waste as a material for making concrete will reduce waste that can pollute the environment. Methodology: The planned concrete compressing strength is fc '= 20 Mpa and the materials to be used are cement, water, sand as fine aggregate and gravel as coarse aggregate. This Research used 25 cylindrical concrete specimens with a variety of ages 3, 7, 14, 21, and 28 days. The process is divided into 6 stages: preparation, aggregate testing, planning (mix design), test specimen production, concrete curing and testing specimens. Results: The results of this Research stated that bottom ash and iron sand waste could be used as a substitution of fine aggregate for making concrete. Based on several tests, the ratio of iron sand waste and bottom ash which is the closest to the gradation of zone 2 (ideal zone) is the percentage of the iron sand waste mixture of 40% - 60% bottom ash that enters zone 2 (rather rough). Suggestions for further Research are to use coarse aggregate whose size varies and use admixture in concrete mixtures. Applications/Originality/Value: Expectations from this Research can provide benefits, among others, can reduce the environmental impact of waste to the surrounding community and provide information for the dive the world community, especially the construction of the benefits and usefulness of iron sand waste and bottom ash as a building material.
