The report presents the principal causes of cracking and reccomended crack control provisions. It covers the basic mechanism of microcracking and fracture mechanics in concrete. It deals with control of cracking due to various causes in the following areas: shrinkage, reinforced concrete beams, one-way and two-way slabs systems, prestressed concrete systems, long term effects including creep and other factors, mass concrete, and construction procedures. The report gives reccomended criteria and equations where necessary for use by the design engineer based on research and applied knowledge in the field of crack control in concrete.
