| 中文摘要: |
| 通过对比试验，研究了不同pH值的饮用水和废水对水泥、粉煤灰性能及混凝土的工作性、耐久性和收缩率影响规律，得到了对混凝土综合性能最有利的水pH值为9，采用废水与饮用水混合调整pH值用于混凝土生产，在保证工作性和耐久性的前提下，提高混凝土28 d强度，实现废水的高效利用。 |
| 英文摘要: |
| Through comparative experiments, the effects of drinking water and waste water with different pH values on the properties of cement and fly ash, as well as the workability, durability, and shrinkage rate of concrete, were studied. It was found that a water pH value of 9 is most beneficial for the comprehensive performance of concrete in terms of strength and workability. By mixing wastewater with drinking water to adjust the pH value for concrete production, the 28-day strength of concrete is improved while ensuring workability and durability, thereby achieving efficient utilization of wastewater. |
