| 摘 要： | 试验研究和分析了矿渣粉掺量对低水胶比混凝土的和易性及强度的影响。结果表明，除了减水剂掺量对新拌混凝土和易性有显著影响外，矿渣粉掺量对混凝土拌合物的和易性有明显改善。水胶比是影响混凝土强度的主要因素，而矿渣粉掺量对混凝土强度的影响也较为明显。矿渣粉的细度小于水泥的细度，可作为细集料用于混凝土中，以改善混凝土拌合物的和易性，降低施工成本。

| Abstract: | In this paper,the influence of low slag dosage on the workability and strength of low water-cement ratio concrete is researched and evaluated.As the results show,in addition to water-reducing agent,slag dosage can clearly improve the workability of fresh concrete.Water-cement ratio is the main factor affecting the strength of concrete,while the slag dosage affects the strength of concrete obriously.As slag fineness is less than the cement fineness,slag can be used as fine aggregate to improve the workabilit... |
