中文摘要: |
胶凝材料(水泥、粉煤灰和矿粉)是影响混凝土质量的重要因素,基于混凝土中胶凝材料化学反应的机理,以及硬化混凝土中测定胶凝材料的不同方法,探讨了这些方法在不同胶凝材料共存时的适应性,认为相对于有机溶剂溶解法,可溶性SiO2法适应性更强;提出可以用粉碎试样测可溶性SiO2法或分离试样测CaO法判断硬化混凝土是否按原配合比施工。 |
英文摘要: |
Cementitious materials (cement, fly ash and slag)is an important factor to the quality of concrete.Based on chemical reactions of cementitious materials in concrete and different methods of measuring cementitious materials in hardened concrete,discuss the adaptability when these methods coexist with cementitious materials. It is considered that the method of soluble SiO2 is more adaptive than organic solvent method; Smashing sample soluble SiO2 or Separating sample CaO methods determines whether constructs according to the original mix ratio. |
