Test Research for Basic Mechanics Performance of Inorganic Polymer Concrete

摘要

The main objective of this study is to evaluate the basic mechanics properties (compressive strength, modulus of elasticity, Poisson's ratio and splitting tensile strength) of inorganic polymer concrete whose mix proportion is ripe recipe and try to provide an experimental and theoretical foundation for application of inorganic polymer concrete in the practical engineering. In this study, the basic mechanics properties of inorganic polymer concrete have been studied by test. At the same time, the same tests researches are made for the common Portland cement concrete for comparison. Through the comparison research, it can be found that the compressive bearing capacity of inorganic polymer concrete is stronger and the modulus of elasticity and Poisson's ratio is slightly bigger than those of common concrete and that the splitting tensile strength is as poor as those of ordinary Portland cement concrete. In order to investigate its long-term performance, the shrinkage and creep tests of inorganic polymer concrete have been studied as well. The change rules of shrinkage and creep in inorganic polymer concrete with time are obtained. It is that initial deformation is bigger and late deformation gradually becomes small and stable. These rules are basic similar as common Portland cement concrete.
