摘要

To research the antifreeze performance of road fiber concrete in an erosive solution, trabecular specimens that contained three kinds of water-cement ratios (0.44, 0.42 and 0.40) were formed. Then, they were placed in distilled water and a 10% Na_2SO_4 solution. The mass, relative dynamic elastic modulus and flexural-tensile strength for each specimen were determined by a freeze-thaw cycle test. The results showed that the mass loss ratio of concrete decreased as the water-cement ratio increased; the elastic modulus and flexural-tensile strength loss ratio increased with it; and the Na_2SO_4 solution exacerbated this trend. In addition, the effect of the water-cement ratio and erosive solutions was mutually reinforcing.

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
