Tóm tắt: At present, the modulus of elasticity, creep and shrinkage properties of concrete that are used in structural design in Florida are based on the arbitrary available literature or based on the limited research of the locally available material. There is a great need for a comprehensive testing and evaluation of locally available concrete mixes to determine these mechanical and physical properties of Florida normal-weight as well as lightweight concretes, so that correct values for these properties can be used in structural designs. The main objectives of this study are to design, evaluate and construct creep test apparatuses that are suitable and effective for performing creep tests on Florida concretes, and (2) to evaluate the compressive strength, indirect tensile strength, elastic modulus, drying shrinkage and creep characteristics of typical Florida Class II, IV, V and VI concrete mixes made with normal-weight and lightweight aggregates. A creep test apparatus was designed, and twelve creep test apparatuses were constructed and set up in the laboratory for use in performing the creep tests in this study. The creep test apparatus was evaluated to be working satisfactorily. An effective procedure for the creep test using this apparatus was developed and documented. This study has generated valuable data and determined general trends on the compressive strength, splitting tensile strength, elastic modulus, drying shrinkage strains and creep coefficient of typical Florida structural concretes made with normal weight and lightweight aggregates.
