Bonding and Strength of Aggregate01:12

Bonding and Strength of Aggregate

1.2K
The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

科学领域:

  • 牙周内科医院 牙周内科医院 牙周内科医院
  • 生物材料科学 生物材料科学
  • 牙科材料 牙科材料

背景情况:

  • 牙修复对于内牙治疗成功至关重要.
  • 生物陶水泥,如矿物三氧化物聚合物 (MTA) 和准备使用的配方 (例如,Bio C Repair) 用于牙修复.
  • 血液污染可能会损害牙科水泥的粘合强度和性能.

研究的目的:

  • 评估MTA和Bio C Repair在血液污染下牙修复中的结合强度.
  • 为了比较常规生物陶水泥 (MTA) 与准备使用的水泥 (Bio C Repair) 在接触血液时的性能.
  • 评估延迟应用对污染环境中的水泥结合强度的影响.

主要方法:

  • 使用了120个牛牙根牙盘,分为对照组和被血液污染的组.
  • (MTA和Bio C修复) 应立即或在15分钟的延迟后应用.
  • 通过使用通用测试机器测量推出键的强度.
  • 进行能量散射X射线光谱 (EDS-X) 和扫描电子显微镜 (SEM) 进行分析.

主要成果:

  • 生物C修复表现出明显高于MTA的键强度 (p < 0.001).
  • 与对照组相比,血液污染显著降低了两种水泥的结合强度 (p < 0.001).
  • 应用15分钟的延迟仅在Bio C Repair样本中降低了结合强度 (p = 0.045).

结论:

  • 血液污染会对MTA和Bio C修复的结合强度产生不利影响.
  • 与MTA相比,准备使用的Bio C Repair在血液污染的牙修复中表现出优异的性能和潜在的更好的处理特性.
  • 尽量减少水泥应用的延迟是很重要的,特别是准备好使用的材料,以保持最佳的结合强度.
