摘要
拆除原有的建(构)筑物 ,对废弃的钢筋混凝土加以利用 ,事关保护生态环境和建筑的可持续发展。利用水能射流破坏钢筋混凝土结构的方法最有前途。将废弃混凝土破碎成再生骨料 ,需要建立一套工艺方法。用5%浓度的盐酸对再生骨料改性的效果明显。使用膨胀剂能够制成C50的补偿收缩再生混凝土。
Demolition of existent buildings and reclamation of reinforced concrete thereof is an issue concerned to ecological environment protection and sustainable development of building industry.Demolishing reinforced concrete structure by using water jet is a method with most desirable prospects.It needs an overall technological process to break reinforced concrete into reclaimed aggregate.5% HCI is used to improve the characteristics of the aggregate and remarkable efficiency is received.Reclaimed C50 compensation shrinkage concrete could be made by mixing with expansion additive.
