Hot Weather Concreting

301
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.
Mitigating the heat increase in concrete can be economically achieved by shading aggregate stockpiles to prevent heating from solar radiation,...

    • 生物材料工程 生物材料工程
    • 恢复性牙科 恢复性牙科

    背景情况:

    • 牙修复手术期间的腹腔内温度 (PT) 变化可能会影响脉活力.
    • 蚀刻和冲洗粘接技术涉及可能产生热量的步骤,可能会影响纸组织.
    • 了解温度波动对于确保牙科修复的长期成功至关重要.

    研究的目的:

    • 为了评估延迟蚀刻和冲洗粘合在V类修复过程中对体内内体温的影响.
    • 在模拟的临床条件下,评估人类前的实时温度变化.
    • 为了确定延迟粘接程序是否会减轻牙纸的潜在热应力.

    主要方法:

    • 在人类前肢上制造了V类制剂,在物质放置之前延迟了15分钟,以恢复生理PT (大约15分钟). 35°C) 的时间.
    • 应用了蚀刻和冲洗粘合剂 (单键通用或四纳米键) 并进行光固化.
    • 牙用常规 (Filtek Z250/Z350) 或散装填充 (Tetric N Ceram Bulk-fill) 树脂复合材料恢复,并进行光固化.

    主要成果:

    • 蚀刻和冲洗程序和溶剂蒸发导致PT的减少,即使在生理水平上启动.
    • 与基线 (38.2°C ± 2.4°C) 相比,只有Filtek Z350的40秒暴露显示了峰值PT显著增加.
