| 摘 要： | 通过系统研究各配制参数(如:碱组分、水胶比、胶凝材料用量等)对碱矿渣混凝土28d抗压强度的影响,深入分析了28d抗压强度分布规律与方差间的关系。结果表明:碱矿渣混凝土28d抗压强度符合正态分布,且与水胶比呈明显反比关系。在此基础上,提出了适用于碱矿渣混凝土的回归方程,确定了公式中回归系数αa和αb分别为0.796和0.897,得出了碱矿渣混凝土配合比参数选择与设计的具体方法。

| Abstract: | This paper examined the effects of crucial parameters, including W/B, binder content, alkali component, on compressive strength of alkali-activated slag concrete.Based on results obtained, the statistical distribution and variance (standard deviation) of compressive strength results were estimated, and the analysis results from experimental data indicated that the compressive strengths of AASC at the age of 28 day fitted normal distribution and is inversely proportional to the liquid-solid ratio.The relationship between W/B and compressive strength was established through regression analysis, the regression coefficient of formula αa and αb is 0.796 and 0.897 respectively.As such, a simple mix design method for alkali-activated slag concrete was proposed. |
