摘要

To no one's surprise, deployment of fiber optic cable directly to homes in North America continues at a steady pace. Earlier this year, the Fiber Broadband Association and research firm RVA, LLC, released its latest report which found fiber deployment reached record highs in 2018. "In 2018, fiber surpassed DSL to become the second-most-common connection for home internet in North America, after cable," stated the report. "In the United States, fiber now passes 41 million unique homes and connects 18.6 million homes. This is a 17-percent increase in homes passed by fiber since 2017. The totals for North America are nearly 60 million homes and 23.8 million connections. Canada leads North American fiber deployment, with a 19-percent growth in the homes marketed in 2018.

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
