Opis

Provides a comprehensive theory for the rational design of concrete mixtures. The results of 12 years of research by the author, it embraces most of the contemporary cementitous materials, and allows the user to achieve an internationally-applicable mastery of concrete material through the use of computer software. The author presents a number of simple models for the understanding of a concrete system, and then provides the techniques for developing more sophisticated models for the practical design of concrete mixes. This should prove a useful reference for academic researchers in civil engineering departments, and tool for technicians in the readymix concrete and prefabrication industries.
