摘要
探讨骨料的含泥量超标、石子超逊径超标对混凝土性能的影响,按L1(644×23)正交表进行混凝土试验设计,利用直观分析和方差分析等手段,进行定性和定量分析砂子含泥量、石子含泥量、石子超逊径对混凝土拌合物、抗压强度、抗渗性及抗冻性的影响。
Explored on the clay content of aggregate and oversize-and-undersize of coarse aggregate exceed standard influence on con crete performance.According to the orthogonal experiments L16（ 4^4x2^3 ） were designed for concrete, used the intuitive analysis and variance analysis methods, qualitative and quantitative analysis of clay content of aggregate, oversize-and-undersize of coarse aggregate effect on concrete mixture, compressive strength, impermeability and frost resistant of concrete.
