地质学和生物学的结合正在给建筑材料带来新突破,这就是能够使裂缝自愈的混凝土。那么其中的秘密武器是什么?答案是细菌。荷兰代尔夫特理工大学教授亨德里克·容克斯过去6年一直尝试开发“生物混凝土”。他在混凝土中添加了特殊的“愈合材料”。当水通过裂缝渗透进混凝土时,这种材料将被激活。当材料被激活后,“魔法”就将上演。容克斯使用了能在强碱性混凝土环境中生存数十年的芽孢杆菌,并利用乳酸钙作为这些细菌的营养来源。这些细菌
The combination of geology and biology is creating new breakthroughs in building materials, which are concrete that can make cracks self-healing. So what is the secret weapon? The answer is bacteria. Hendrick Junkers, professor at Delft University of Technology, Netherlands, has been trying to develop “bio-concrete” for the past six years. He added special “healing material” to the concrete. This material will be activated when water penetrates the concrete through cracks. When the material is activated, “Magic ” will be staged. Junkers uses Bacillus that can survive decades in strongly alkaline concrete environments and uses calcium lactate as a source of nutrition for these bacteria. These bacteria
