ABSTRAK
In the Riau Province, there are 1,534.581 hectares of oil palm plantations (PKS), which produce 15.2 million tons of solid trash year and 28.7 million tons of liquid waste annually. Every year the area of oil palm plantations has increased. Every 1 hectare OPM produces around 1.5 tons of solid waste of empty palm fruit bunches (EFB) annually in a dry state and 2.64 tons of EFB with a moisture content of 50%. The waste from the combustion results in POFA (Palm Oil Fuel Ash) or also known as palm ash. POFA is a good material as a substitute for cement, but the use of palm ash effluent as a substitute for cement is not very reactive, this requires the addition of materials that have pure pozzolanic properties such as silica. The addition of silica will increase the reactivity of POFA as a substitute for cement. This study aims to review the characteristics of silica POFA concrete including compressive strength, tensile strength, setting time, strength activity index (SAI), and density of silica POFA concrete aged 7, 28, and 91 days in ordinary water immersion. The highest compressive strength test result was on 100% PCC control concrete which was 32.58 MPa and the lowest test result was on concrete with 20% POFA which was 9.40 MPa. The highest split tensile strength test results were on 100% PCC control concrete, namely 29.73 Mpa and the lowest concrete split tensile strength was on the POFA PCC variation, namely 9.74 Mpa. This is because the use of cement is reduced by 20% and the silica content in POFA is low. The content of silica (SiO2) in POFA is 37.127%, causing the concrete mixture to not react properly and slow the reaction of the pozzolanic contained in the cement as a binder, thereby reducing the increase in the compressive strength value which is not too significant in the POFA concrete mixture with silica mixture
Keywords: concrete, blended concrete, POFA, silica
