摘要

The investigation of the mechanical behavior of resin concrete is becoming important, as the types of resins are increasing and the use of resin concrete is no longer limited to repair work. The structural use of rsin concrete requires accurate design that can be achieved through the utlization of the Finite Element method which requries a complete constitutive model and full understanding of the mechanical behavior of the resin concrete. The invesigation of stress-strain relations under repeated loading for resin concrete cylinders, prepared using different types of resins and different ratios of resins to aggregate and subjected to different temperature stations was carried out.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
