Deteriorated Concrete(劣化混凝土)研究综述
Deteriorated Concrete 劣化混凝土 - Mass loss, dynamic elastic modulus, compressive strength, and sulfate ions distributions of deteriorated concrete were measured over time. [1] The electrochemical deposition method is a promising approach to repair the deteriorated concrete in the aqueous environment. [2] A delicate restoration has allowed to remove the deteriorated concrete and to restore the resistant sections with new materials compatible with the old remaining structures. [3] A promising field of application is the rehabilitation and/or strengthening of existing reinforced concrete structures, in which a new layer of UHPFRC replaces the deteriorated concrete (cracked, carbonated, chloride attack, etc. [4] To study the pure mode II fracture toughness of deteriorated concrete, anti-symmetrical four-point bending (ASFPB) tests were conducted on the corroded concrete specimens. [5] In this study, the possibility of the prevention of deterioration or delay of deterioration of concrete was investigated using natural latex modified with silica sol and calcium ions for cement mortar, which can be used to repair the mortar of deteriorated concrete or for finishing the mortar of concrete. [6]随着时间的推移，测量了劣化混凝土的质量损失、动态弹性模量、抗压强度和硫酸根离子分布。 [1] 电化学沉积法是修复水环境中劣化混凝土的一种很有前景的方法。 [2] 精细的修复可以去除劣化的混凝土，并使用与旧的剩余结构兼容的新材料修复抗性部分。 [3] 一个有前途的应用领域是现有钢筋混凝土结构的修复和/或加固，其中新的 UHPFRC 层取代了恶化的混凝土（开裂、碳化、氯化物侵蚀等）。 [4] 为了研究劣化混凝土的纯II型断裂韧性，对腐蚀的混凝土试件进行了反对称四点弯曲（ASFPB）试验。 [5] 本研究采用硅溶胶和钙离子改性的天然胶乳作为水泥砂浆，研究了防止或延缓混凝土劣化的可能性，该胶乳可用于修复劣化混凝土的砂浆或用于修整混凝土砂浆。具体的。 [6]
deteriorated concrete bridge 恶化的混凝土桥
Volume 2 presents two experimental programs that were conducted to develop and evaluate various repair and strengthening methodologies used to restore the performance of deteriorated concrete bridge beams. [1] Taking such complexity into account, the current paper presents a new stochastic predictive methodology using a non-homogeneous Markov process, which directly relates the visual inspection data (corrosion rate and crack widths) to the structural vulnerability of deteriorated concrete bridges. [2] Volume 2 presents two experimental programs that were conducted to develop and evaluate various repair and strengthening methodologies used to restore the performance of deteriorated concrete bridge beams. [3] Asphalt overlays have been commonly used to extend the service life of deteriorated concrete bridge decks. [4]第 2 卷介绍了两个实验计划，这些计划旨在开发和评估用于恢复劣化混凝土桥梁性能的各种修复和加固方法。 [1] 考虑到这种复杂性，本文提出了一种使用非均匀马尔可夫过程的新随机预测方法，该方法直接将目测数据（腐蚀率和裂缝宽度）与劣化混凝土桥梁的结构脆弱性联系起来。 [2] 第 2 卷介绍了两个实验计划，这些计划旨在开发和评估用于恢复劣化混凝土桥梁性能的各种修复和加固方法。 [3] 沥青覆盖层通常用于延长老化混凝土桥面的使用寿命。 [4]
deteriorated concrete structure 劣化的混凝土结构
This is because the government has allocated a considerable budget to repair the existing deteriorated concrete structures due to the corrosion of the reinforcement. [1] This paper attempts to tabulate a schedule of multiple repair required by a Markov-deteriorated concrete structure. [2] Due to this factor, the understanding on the electrochemical behavior of reinforcing steel bar using different materials for repairing for deteriorated concrete structures will be considered. [3]这是因为政府已拨出可观的预算来修复因钢筋腐蚀而导致的现有劣化混凝土结构。 [1] 本文试图将马尔可夫劣化混凝土结构所需的多次修复时间表制成表格。 [2] 由于这个因素，将考虑对使用不同材料修复劣化混凝土结构的钢筋的电化学行为的理解。 [3]

This research aims to evaluate the applicability of deteriorated concrete pavement to reconstruct new pavement in an economical and sustainable approach.

[2] Generally, a deteriorated concrete pavement is restored by a layer of asphalt reinforcement.
