Abstract
Different from ordinary Portland cement concrete, the inorganic polymer concrete is a new type of concrete and is made through replacing Portland cement with inorganic polymer material in common concrete. To popularize and apply inorganic polymer concrete in prestressed structure, this paper carried out a series of experimental study on prestressed beam of inorganic polymer concrete for the purpose of providing experimental basis and theoretical grounds for its application in practical engineering. Firstly, the basic mechanics properties (compressive strength, modulus of elasticity, Poisson’s ratio and splitting tensile strength) of inorganic polymer concrete were presented and discussed. Secondly, in order to investigate its serviceability, durability, and stability of member subjected to load for long-term, the shrinkage and creep tests for inorganic polymer concrete have been studied as well. Thirdly, based on the test research of basic mechanics performance, test researches on prestressed beams of inorganic polymer concrete were carried out. Through these tests, this paper put forward a kind of new model to predict the shrinkage and creep for inorganic polymer concrete, and presented a calculation method for prestressing loss due to anchorage slip and prestressed tendons retraction when the reverse friction length is longer than the total length of member, and obtained the calculation formulas of cracking and ultimate load for prestressed beam of inorganic polymer concrete. The theoretical analysis and experimental results are in good conformity. These show that the theoretical model, method and formula suggested by this paper for inorganic polymer concrete member are feasible.
