The mechanical properties of concrete have been measured experimentally In many places and their correlation given in some technical standards. However, the mechanical properties of concrete are dependent on many factors, including the characteristics Of the raw materials used, the curing conditions and the local concrete practice, which may vary from place to place. Hence, the mechanical properties measured in other places may nat be directly applicable to Hong Kong. In this study, the cube compressive strength, split cylinder tensile strength, static modulus and dynamic modulus of typical concrete produced in Hong Kong using the local materials under the local conditions were measured and best-fit equations correlating the various mechanical properties derived. The measured results were also compared to theoretical predictions by various correlation equations developed elsewhere to evaluate their applicability to Hang Kong. Concretes with cube compressive strength ranging from 1 to 60 MPa were covered in the study. |
