最近,韩国江原大学石料复合新教材研究中心延圭锡教授领导的研究小组最近宣布:用采煤后废弃的煤矸石制成的“聚合物混凝土”替代混凝土的新技术已经开发成功。 在韩国科学财团的支援下,从1995年开始仅l年时间就开发成功的这种“聚合物混凝土”是用沙石粉碎机将经过粉奉的直径为13mm的煤矸石颗粒和沙子以7:3的比例搅拌后,加入耐蚀的合成树脂制造而成。该材料与原来的混凝土相比,强度提高4～5倍,且吸振能力
Recently, a research team led by Prof. Keisuke Yoshiyoshi of the New Materials Research Center for Stone Composites at Gangwon University in Korea recently announced that a new technology for replacing concrete with “polymer concrete” made from coal gangue abandoned after coal mining has been successfully developed. With the support of the Korea Scientific Foundation, this “polymer concrete” that was developed successfully only for one year since 1995 is the use of sand grinders to pulverize powdered gangue particles and sand with a diameter of 13 mm to 7: The proportion of 3 was stirred and then a corrosion-resistant synthetic resin was added. Compared with the original concrete, the material has a 4 to 5 times stronger strength and absorbs vibration.
