Based on the experimental study of cement concrete, this book systematically introduces the basicmethod of orthogonal design and its application in concrete from the point of view of mathematicalstatistics, mainly including optimizing the mineral composition of high-strength Portland cementclinker, optimizing the variety and quantity of water-reducing agent, configuring special concrete andselecting concrete mix. The application of mixing ratio, researching concrete performance, optimizingconcrete forming, steam curing technology and so on.This book can be used for reference by researchers of concrete materials and constructiontechnicians of concrete works.
