Considering the defect of easily mildewing of the bamboo particle concrete form, the experiments on the relationship between density and antimould property of the form with five antimould chemicals were carried out. The results showed that the density had a significant linear relationship with the antimould property of the panel. The panels treated with the antimould agent NPFB had the ideal antimould property and the main physical and mechanical properties of concrete form made of them could meet the requirements of the standard JG/F 3026 1995.
