23 The Concrete Construction ProcessUnderstanding Cement

For this reason it is not a good idea to completely separate the science of concrete from the more mundane process of making it No one expects contractors and construction workers to manufacture plate glass extrude pipe or press drywall but they are regularly expected to make good quality concreteInterpreting Cement Science Cement and concrete materials science is a multidisciplinary subject involving engineers geologists chemists physicists and many others This website is for the great majority of us who aren t university professors of cement chemistry but whose work requires a good understanding of the subject
