Quality of Water01:19

Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
Testing Water Quality01:14

Testing Water Quality

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

  • 公共卫生 公共卫生
  • 水的质量 水的质量

背景情况:

  • 数以百万计的美国家庭依赖私人井来获得饮用水.
  • 私人井水的检测和处理不足可能导致广泛的污染暴露.
  • 了解家庭对私人井水的行为对于公共健康至关重要.

研究的目的:

  • 总结爱荷华州私人井户的饮用水行为和看法.
  • 通过随机对照试验,评估酸盐测试条和免费测试计划对家庭行为和感知的影响.
  • 评估干预措施的成本效益和福利影响.

主要方法:

  • 在爱荷华州对私人井户进行了一项大规模的调查.
  • 使用随机对照试验 (RCT) 来测试干预的有效性.
  • 干预包括酸盐测试条和免费水质测试计划的信息.

主要成果:

  • 很少有家庭遵守推的水检测频率.
  • 大约40%的家庭表现出风险行为 (不检测,治疗或避免用水).
  • 该干预措施显著增加了水检测率,包括高质量的后续测试,但对其他行为和感知的影响有限.

结论:

  • 爱荷华州的私人井水测试和处理行为低于最佳水平.
  • 经过测试的干预措施有效地促进了水的测试,并提高了福利.
  • 可能需要进一步的策略来解决与私人井水安全相关的更广泛的行为和感知问题.
