摘 要:研究了一种黏度改性材料或石灰石粉与矿粉复掺对清水混凝土力学性能、抗渗性能和外观质量的影响。结果表明:用8%的黏度改性材料或15%的石灰石粉与矿粉复掺对提高清水混凝土的抗压强度、降低其电通量和氯离子扩散系数的效果相对较好;复掺黏度改性材料或石灰石粉制备的清水混凝土外观颜色偏亮,表面平整光滑,气泡较少。
Abstract: The effects of dosage of viscosity-modified material and limestone powder on mechanical properties, impermeability and appearance of fair-faced concrete with mineral powder were studied. The results show that 8% of viscosity modifier or 15% of limestone powder and mineral powder have relatively good effects on improving the compressive strength of fair-faced concrete and reducing its electric flux and chloride ion diffusion coefficient. The fair-faced concrete prepared by adding viscosity modified material or limestone powder has a brighter appearance, smooth surface and less air bubbles.
