What is Geopolimer dari Abu Vulkanik Merapi about?

The document summarizes research on synthesizing geopolymer cement using volcanic ash from Mount Merapi eruptions in Indonesia. The research aims to determine the feasibility of using volcanic ash as a raw material for geopolymer and optimize the process to achieve high compressive strength. Results found that volcanic ash contains high levels of alumina and silica, suitable for geopolymer production. The highest compressive strength of 16.81 MPa was achieved with specimens heated for 12 hours at 80°C and c
