概括

建筑工地产生大量颗粒物 (PM) 污染. 较小的颗粒 (PM1,PM2.5) 影响较大的颗粒 (PM10),即使在活动较低时,危险水平也经常持续存在.

科学领域:

环境科学环境科学
职业健康职业健康职业健康
空气质量监测空气质量监测

背景情况:

建筑活动是颗粒物 (PM) 污染的主要来源.
建筑业现有的颗粒物减轻策略尚未得到充分探索.
对于环境和运营因素如何影响现场PM动态的理解有限.

研究的目的:

在一个活跃的建筑工地调查PM1,PM2.5和PM10相互作用.
分析环境和运营驱动因素对PM动态的影响.
了解较小的 PM 分数对较大的 PM 度的调解作用.

主要方法:

高分辨率的PM1,PM2.5和PM10的实时监测.
收集了来自建筑区和外部参考点的28000多项测量结果.
分析颗粒物度,环境因素 (如温度) 和操作场景之间的关系.

主要成果:

PM1和PM2.5作为影响PM10度的关键中间体.
PM10的峰值为1763.37μg/m3,明显超过了监管限制.
温度和建筑活动对PM10的影响主要是通过它们对PM2.5的影响 (分别为57%和72%的介导).
在低活动时期的81.61%发现了危险的颗粒物含量,这表明存在残留暴露风险.

结论:

在现场,多指标监测系统对于捕获动态的PM变化至关重要.
了解PM相互作用是制定针对建筑环境的有针对性的缓解策略的关键.
这些发现为推进建筑环境中的空气质量管理提供了基础,解决了对工人和附近人口的风险.

Effects of Air-entrainment in Concrete

Effects of Air-entrainment in Concrete

Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...
