混凝土早期强度 meaning in English
early age strength of concrete
Examples
- Early age strength of concrete
混凝土早期强度 - Aiming at this problem , the paper put forward a dynamic concrete strength testing technology - consolidating wave speed method , and it can be used to testing fresh concrete strength real - timely
针对这一问题，本文提出了一种实时监测混凝土早期强度的动态、无损检测方法- -固结波速法。 - The facial and pore properties of lightweight aggregate and transition zone of lwac is studied by the means of sem and xrd . it is concluded that the " embedded " transition zone of lightweight aggregate - paste makes the principle contribution to the higher early strength of lwac . meanwhile , the " internal curing " of the double pore structure in lwac has been proved
本文利用xrd和sem等现代测试手段对轻集料的表面和孔特性以及轻集料和水泥石的界面结构进行了系统研究，揭示了轻集料和水泥石的“嵌套”界面结构是轻集料混凝土早期强度高的根本原因和轻集料对水泥石的“自养护”作用规律。 - Based on quite a few literatures , the paper discusses the method to researching slump loss ; researches the mechanism of slump loss and compares several measures which are used to control slump loss . it ' s believed that retardarce method can constrain the slump loss of fresh concrete effectively and have no bad influence on the early strength of concrete
论文在查阅大量文献的基础上，系统探讨了坍落度损失的研究方法，深入研究了坍落度损失的机理，比较了控制坍落度损失的几种措施，认为缓释法能够有效地抑制新拌混凝土的坍落度损失，且对混凝土早期强度无不利影响。
