中文摘要 | 水泥及混凝土的應用已與各種摻料的使用構成緊密的關係。從拌合、輸送、澆置 、凝結到硬化,摻料在混凝土中都發揮著不同的作用。現代水泥及混凝土在應用與性能的兩 項重大突破。即耐寒性的改善和高強度混凝土的開發,分別是因輸氣劑和高性能減水劑兩種 摻料的開發所致。本文針對各種摻料的特性及作用做一介紹,並對影響混凝土的使用和性質 較顯著的摻料,即減水劑、強塑劑、緩凝劑、促凝劑及輸氣劑,做較詳細的作用機構說明。 |
英文摘要 | The use or application of modern cement and concrete have close relationships with additives known generally as admixtures. These additives provide indispensable contributions to the mixing, transport, casting, setting and hardening of cement and concrete. Two of the most important breakthroughs in the applications of modern cement and concrete, namely the improvement on their durability in low temperature environment and the development of high strength concrete, were due to the development of two admixtures, namely air entrainment agents and super plasticizers respectively. The present article gives a general introduction to the major types of admixtures. For the most important ones, i.e. water reducing agents, super plasticizers, set retarders, set accelerators and air entraining agents, the mechanisms of their action are also mentioned. |
