Sidoarjo mud: creating worth from waste

Abstract

Sidoarjo mud (SM) is generated in considerable amounts from a volcano mud eruption caused by drilling from a gas exploration in the Porong area, Sidoarjo, East Java, Indonesia. The eruption of Sidoarjo mud has damaged the environment and destroyed a significant number of villages. Because of this, a study has been undertaken to convert this material from waste to valuable material in concrete construction. It is noted that Sidoarjo mud is perceived as a material that can be used as a partial cement replacement material called pozzolanic, and also as a source material for geopolymer concrete. Some studies revealed that the overall chemical composition of Sidoarjo mud is similar to Portland cement (OPC), and it is known that the content of Si, Al and Fe in SM is higher than in OPC. It is also known that the chemical composition Si, Al and Fe are the important elements in concrete especially for the properties development. In this study, it is evident that for conventional concrete, SM has clearly provided increased compressive strength and tensile strength at 10% replacement of cement weight by 26% and 9%, respectively.
