碩士 === 正修科技大學 === 營建工程研究所 === 103 === Desulfurization steelworks slag is solid waste arising from the blast furnace via desulfurizer desulphurization, the annual output of about 250,000 tons, desulfurization slag is a general industrial waste, the Environmental Protection Administration Announcement of "recyclable waste." In this study, desulfurization slag, furnace slag, fly ash and other admixtures replace most of the cement, to find the best ratio in order to reduce consumption and waste of natural resources regeneration, the purpose of recycling. In this study, we desulfurization slag and furnace slag, fly ash and cement into cement mortar test body of data obtained through the compression test to identify the most economical and best compression ratio specification standards. The results of this study show that the desulfurization slag fineness, temperature increase, the early compressive strength better, will affect the amount of desulfurization slag Mortar result, add another bit of ash on the strength of the contribution, adding furnace powder contribute to the strength of the obvious.
