摘要

路边安全护栏是在赛道周围或双车道高速公路中间设置的保护性护栏，目的是减少事故的严重性。最近，对便携式路边安全屏障的兴趣增加了对开发低成本和高性能替代传统安全屏障系统的兴趣。采用发泡外加剂对烟气脱硫泡沫混凝土(CC)的新鲜和硬化特性进行了研究，以开发轻型路边安全屏障。试验结果表明，掺加发泡外加剂的烟气脱硫复合材料可有效地用于制造轻型道路安全护栏。

Development of Lightweight Roadside Safety Barriers using Foaming Admixture: Phase I - Properties of Flue Gas Desulfurization (FGD) Cellular Concrete

The roadside safety barrier is a protective barrier that is erected around a racetrack or in the middle of a dual-lane highway in order to reduce the severity of accidents. Recently, interest in portable roadside safety barriers has heightened the interest in the development of a low-cost and high-performance alternative to the conventional safety barrier system. A study has been undertake to characterize fresh and hardened properties of flue gas desulfurizaiton (FGD) cellular concrete (CC) using foaming admixture towards the development of lightweight roadside safety barrier. Test results indicate that FGD CC using a foaming admixture can be effectively used in manufacturing lightweight roadside safety barriers.
