美国俄亥俄州的研究人员发明了一种使混凝土能保持可塑性的新技术,这项被称为Delvo的新技术只要加二种特殊化学物质,就可使水泥交替地停止或产生水化反应。如要阻止混凝土固化时,只需添加适量稳定剂就能包住水泥颗粒,使其停止水化反 Researchers in Ohio, USA, have invented a new technology that allows concrete to maintain its plasticity. This new technology, called Delvo, allows the cement to alternately stop or produce a hydration reaction as long as two special chemicals are added. If you want to prevent the concrete from solidifying, just add an appropriate amount of stabilizer to envelop the cement particles and stop it from hydrating.
