above-normal loss
解釋
超正常損失-
The shrinkage characteristics of hsc and normal concrete at short term and long term are researched. based on the above research, high performance expansive c50 - c80 concrete, which posses good expansive properties, excellent flow ability, low slump loss and hydration heat. in order to improve the anti - cracking of some important projects, such as cutting wall, the workability and bulk stability of fiber - reinforced micro expensive concrete are researched
針對高強混凝土的收縮特性以及性能特點,本文提出將膨脹劑引入高強混凝土內進行補償收縮,研究了粉煤灰、礦渣、硅灰等摻和料對混凝土工作、力學耐久性能的影響和c50 c80高強微膨脹補償收縮混凝土的力學與工作性能,配製出具有很好的可泵性能和耐久性能的混凝土。
