    Abstract

    A mud volcano has been emerging since May 2006, in Sidoarjo, Indonesia, as a result of faulty in oil drilling. Since then, the mud has submerged more than 700 hectares of productive land, housing and industrial areas and infrastructures. To date, the eruption still continues, and there is no sign that it will end in the near future. The contents of mud are predominantly SiO2, Al2O3 and Fe2O3 in crystalline form, with the total amount more than 80. This paper reports an attempt to utilize the volcanic mud in high volume volcanic mud mortar and concrete. After pre-treatment in the form of calcinations and grinding, the volcanic mud was found to be reactive. Treated volcanic mud in the amount up to 60 of the total cementitious material was utilized to produce mortar and concrete. The main variables were the fineness of the treated mud and the amount of the mud. It was found that the particle size of the treated mud plays an important role on the properties of mortar and concrete, whereby the finer provides the better properties. With 60 usage of volcanic mud of the total mass of cementitious material, the strength activity index (SAI) of the mortar at the age of 7, 14, 28 and 56 days were found to be more than 80. This study reveals the potential of volcanic mud from Sidoarjo, East Java, Indonesia, to be used as pozzolanic material in high volume volcanic mud mortar and concrete.
