Fracture Mechanics Test Methods For Concrete

"Compares currently used methods in determining concrete toughness and presents recommended test procedures with theories and models for describing cracking and fracturing phenomena. Effects of loading rate, temperature and humidity are also examined. Well referenced and illustrated, this book is filled with practical technical information for materials and structural engineers."--Provided by publisher.
