摘要
本研究全面测试了超细加工的四种不同细度的天然硅灰石矿物的细度与活性 ,并用逐步回归分析的方法建立了粉体细度与活性的数学模型 .研究表明 ,建立的二次数学模型能够准确地描述细度、掺量与水泥基材料各龄期的抗压强度、抗折强度。
The paper systematically studies the relationship of fineness and activity of four different fine natural Wollastonites, and sets up the mathematic model with step by step regression design. The quadric mathematical model can describe accurately the inner relationship among fineness, radio and compressive strength, bending strength of cement base material at different caring ages.
