Workability and Mechanical Properties of Heavyweight Magnetite Concrete. Paper by Keun-Hyeok Yang, Jae-Sung Mun, and Ho Lee/AUTHORS' CLOSURE
The discussed paper describes a research work which aimed to provide basic data for developing mixing details and design models for structural heavyweight concrete (HWC). Eighteen concrete mixtures containing different replacement levels with conventional normalweight aggregates (natural sand and granite coarse) for fine and coarse magnetite aggregates were examined. The authors should be congratulated for carrying out a careful experimental study that reports valuable findings on the mechanical properties of HWC, including density, compressive strength, splitting tensile strength, modulus of elasticity, modulus of rupture, direct shear strength, bond strength, and amount of slip of a reinforcing bar at peak bond stress, which were inconsistent mostly with the predictions obtained from main codes such as ACI 349 and CEB-FIP. The discusser would like to thank the authors for providing a detailed paper, and would also like to offer the following comments and questions for their consideration and response. The authors state that the properties relevant to strength are generally proportional to a power function of concrete compressive strength.
