rough concrete 中文意思是什麼
rough concrete
解釋
毛面混凝土-
The scc has the following advantages : remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing - vibration or excessive - vibration in conventional construction, resolving the quality - defect problems resulting from lacking - vibration in the section of complex shapes and densely - packed reinforcement area. at the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of scc. it is helpful in comprehensive utilization of resource and environment protection, so the scc belongs to " green concrete ", it is a branch of hpc which will be developed in the future
這種混凝土可以顯著降低混凝土施工中的噪音污染；大幅度減輕工人的勞動強度；減少傳統混凝土施工中因漏振或過振造成的麻面或離析；解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題；同時，由於自密實混凝土在配製中，大量利用粉煤灰、高爐礦渣等工業固體廢棄物，有利於資源的綜合利用和生態環境的保護；從而被譽為「綠色混凝土」 ，是未來混凝土向高性能發展的方向之一。 -
Aiming at crack problems in important hydraulic concrete structures, the cause, evolution rule and abnormality diagnosis of the crack are studied in this dissertation by using advanced theories and mathematics and mechanics, such as rough set theory, data mining, neural network, wavelet analysis, chaos theory, and so on, combining with prototype observation data. the main contents are as follows. ( 1 ) mining of cause of crack is proposed by using logic diagnosis, rough set theory, and data mining technique
