Karakteristik Beton Blended Pofa Dengan Campuran Silika Di Air Gambut

---

ABSTRACT
Concrete that uses POFA (Palm Oil Fuel Ash) as a replacement of cement and a silica combination is known as POFA-blended concrete with silica as reactivity improvement material for POFA. This study aims to examine compressive strength, porosity, shrinkage, weight change, and the effect on environment using Toxicity Characteristic Leaching Procedure (TCLP) in peat water curing for 0, 7, 28, and 91 days. The POFA blended concrete with a mixture of silica in this study were POFA 20%, POFA 18% + Silica Fume 2%, and POFA 18% + Precipitated Silica 2%. The control concrete has a design compressive strength of 20 MPa and made of 100% PCC. Compressive strength test shows that PCC POFA SF concrete has a highest compressive strength value of 21,40 MPa at 91 days old. The porosity test results showed that PCC POFA SP produced the lowest porosity, which was 13,004% at the age of 91 days. The shrinkage test showed that the lowest shrinkage value was at PCC POFA, which was 0,08% at the age of 28 days. Weight change test shows that PCC POFA SP has the lowest weight change value of -0,028% at the age of 91 days. The AAS test results at 28 days showed that the level of heavy metals in the POFA blended concrete with a silica mixture were remained below the quality standard in PP No. 101 of 2014. Based on the test results, POFA blended concrete with a silica mixture shows good potential for usage as an innovation in POFA blended concrete in peat water to increase POFA reactivity.
