ANALISIS SIFAT FISIK DAN MEKANIK GEOPOLYMER FOAM CONCRETE DENGAN VARIASI RASIO FOAMING AGENT DAN AIR

Geopolymer is the synthesis of inorganic natural materials through a polymerization process. The mainingredients in manufacture geopolymers are containing silica and alumina. Geopolymermaterial can be obtained from coal industry waste products such as fly ash. Innovative technology inmanufacturing foam concrete widely used building construction, using earthquake-resistantbuilding walls energy-efficient buildings. In this study, geopolymer was manufacturedby combining mixture foam. A solution 14 M NaOH Na2SiO3with ratio 2.5 an activator. Fly ash precursor, foaming agent andwater 1:20, 1:30, 1:40, which material for making This study aimed todetermine concrete's physical mechanical properties with various agentsand water. results testing air content fresh indicate that use more foamingagents improve quality reduce theconcrete so it increase compressive strength test object. fewer density concrete.
