Abstract
The mechanical properties of artificial lightweight geopolymer aggregate (ALGA) using volcano mud in concrete have been investigated at various sintering temperature. The volcano mud was mixed with alkaline activator, formed into spherical pellets, then sintered in the furnace at temperature of 500°C, 600°C, 700°C, 800°C, 900°C, 950°C, and 1000 °C. The lightweight concrete with density below than 1800 kg/m3 can be achieved at sintering temperature ALGA of 950 °C. The optimum compressive strength of 30.1 MPa was achieved at 28 days of testing. The lower water absorption of ALGA concrete was produced with 5-8 in range.
