It can use transcendental equations to predict the corrosion initiation time of concrete bridge decks based on the measured surface chloride concentration.
通过对钢筋混凝土桥面板表面氯离子浓度的测量,并运用超越方程预测钢筋混凝土桥面板锈蚀的开始时间,即采用三种不同表面氯离子的浓度-时间关系曲线,根据不同的扩散系数和混凝土层深度对锈蚀开始时间进行预测,这对于桥面板的维护和修复有重要的参考价值。
The second and the third chapter is the core of the paper,which analyses the emotional experience in the Time of Beginning and poems at jail respectively.
第二章和第三章是论文的核心部分,分别就《时间开始了》和《狱中诗草》两部诗集中的情绪体验展开剖析,以重新认识胡风诗歌的文学价值,同时通过分析他建国后诗歌的内在变化以及从自由诗到古体诗转变的心路历程,还原出一个完整、真实的情绪系统,由此深入到诗人复杂的精神世界,了解诗人在复杂的历史境遇下所坚守和执着的信仰所在。
Free linear change and strength development of the corresponding mortars under drying and water curing conditions were studied;and the initial cracking time of mortars cured at drying conditions was detected using a five-group crack apparatus.
结果表明:在常温条件下减缩剂会延缓水泥早期水化,而在半绝热条件下则会加速水泥早期水化;减缩剂主要提高干燥环境下的水泥砂浆的抗裂性能,降低其线性收缩值与强度增长,推迟其约束收缩初始开裂时间,而对水中养护的砂浆无补偿收缩效应,因此不利于控制热裂缝。
The results show that PNS has improved initial cracking time o.
结果表明,掺萘系高效减水剂延长了砂浆初始开裂时间,从而降低了砂浆的开裂敏感性,且高浓型比普通型更能有效地降低砂浆开裂敏感性。
The results show that when dosage of GGBFS is 40%～50%, initial cracking time of mortar blending GGBFS increases and non-restrained shrinkag.
结果表明,矿渣微粉掺量为40%～50%时,胶砂初始开裂时间明显增长,混凝土自由收缩减小,混凝土早期收缩开裂性能显著改善,混凝土抗压强度达到最高;标准养护条件比干燥养护条件对矿渣微粉混凝土强度的发展更有利。
