Coke-oven workers are exposed to dust and irritant gases. Therefore they are at risk of developing lung diseases including chronic bronchitis. Nonspecific bronchial hyperresponsiveness (BHR) has been advocated as a potential risk factor predisposing to the development of chronic bronchitis. In a previous study, we showed that prevalence of BHR was higher in retired coke-oven workers than in ret...

In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...

Abstract The effects of fly ash, Air Cooled Blast Furnace Slag (ACBFS), and silica fume on cement compressive strength are examined. concrete is studied by the addition air-cooled blast furnace slag fume. effect ACBFS, was investigated. content reduced 25%, 22.50%, 20%, 17.50%, respectively; ash used to replace 40%, 60% coarse aggregate; partially replaced 2.5%, 5%, 7.50% content. Contrarily, l...

The effects of coke mineralogy on reactivity under conditions representative the blast furnace were studied. Coke samples reacted index (CRI) like (1100°C, 100% CO2) and at higher temperatures atmospheres designed to replicate lower in furnace.
