This study was aimed to find the possibility of foundry use of the river sand of Chuncheon as moulding sand. Moulding sand samples from five different areas of Chun-Cheon district were tested according to the moulding sand specifications of Korean Industrial Standards. The sand tests on clay contents, grain fineness, permeability, compression strength, surface hardness, chemical composition and mixture were carried out. Comparing the test results of this study with the reported data of the domestic moulding sands from other districts, it was concluded that the Chuncheon moulding sand deserved being developed for foundry use from the viewpoint of its quality as well as its quantity.
