vibrated concrete 中文意思是什麼
vibrated concrete
解釋
振搗過的混凝土-
In addition, vibration has great effects on uniformity of high fluid structural lightweight aggregate concrete. there is obvious separation of lightweight aggregate from mortar in mixture of high fluid structural lightweight aggregate concrete with slump of 220mm when vibrated for 10 minutes
此外，振動對大流動性輕集料混凝土的勻質性十分不利，對坍落度220mm左右的輕集料混凝土拌和物，振動時間超過10秒，就會出現明顯的分層現象。 -
As the concrete members are vibrated from 12 to 72 hours, the difference of its strength between vibration members and normal ones is not obvious. the interface of post - casting section is both the most dangerous position of the structure and focal point of quality control. in addition, the leaking of cement paste out of the formwork of vibration member is of no permission
試驗表明振動持續時間從12小時到72小時的變化，對混凝土強度沒有明顯差別；濕接頭的界面是最薄弱部位是施工質量控制的重點，振動構件模板應做到務必不漏漿；當振動幅值較大，必須採取隔振、減振措施。
