Kuat Tekan dan Perubahan Berat Beton OPC dan OPC POFA dengan Menggunakan Air Gambut sebagai Air Pencampur di Lahan Gambut

This research study the compressive strength and mass loss of OPC concrete and concrete combine of OPC +10% palm oil fuel ash (POFA). The specimens cured in peat environment until 28 days. Compressive strength of concrete OPC G higher than OPC POFA G because reaction of pozzolanic make slowly calcium silicat. Weight changes showed OPC G until 28 days increased because acid can make expantions so volume of concrete increased. Concrete OPC G +10% POFA decreased because reaction pozzolanic can less acid for concrete
