Abstract
Generally, the geopolymer is manufactured through high temperature curing and aging steps after molding. Before high temperature curing, the process of allowing it to stand at room temperature for a certain period was introduced, the process was called precuring. Geoplymers were cured for 3, 7, 28 days including precuring process, and physical and chemical properties were evaluated As a result, specimen with precuring time of 13 days exhibited a maximum compressive strength of 76.31 MPa, compared with the compressive strength of specimen made without precuring process (31.7 MPa), the compressive strength was increased by 2.4 times. It was found that precuring was effective in improving the compressive strength.
