五、混凝土中氯离子的来源：

氯盐是廉价而易得的丁业原料，它在水泥生产中具有明显的经济价值。它可以作为熟料煅烧的矿化剂，能够降低烧成温度，有利于节能高产；它也是有效的水泥早强剂，不仅使水泥３ｄ强度提高５０％以上，而且可以降低混凝土中水的冰点温度，防止混凝土早期受冻。氯离子的来源主要是原料、燃料、混合材料和外加剂，但由于熟料煅烧过程中，氯离子大部分在高温下挥发而排出窑外，残留在熟料中的氯离子含培**少。如果水泥中的氯离子含量过高，其主要原冈是掺加了混合材料和外加剂（如：工业废渣、助磨剂等）。因此，在我国水泥新标准中增加了“水泥生产中允许加入≤０．５％的助磨剂和水泥中的氯离子含量必须≤Ｏ．０６％”的要求”，这主要是为了保证水泥不对混凝土质量产生过多负面影响。

V. Sources of chloride ion in concrete:

Chloride is a cheap and readily available raw material for Ding industry, and it has obvious economic value in cement production. It can be used as a mineralizer for calcining clinker, which can reduce the firing temperature and is conducive to energy saving and high yield. It is also an effective early strength agent for cement, which not only increases the 3d strength of cement by more than 50%, but also reduces the freezing temperature of water in concrete. To prevent early freezing of concrete. The sources of chloride ions are mainly raw materials, fuels, mixed materials and admixtures. However, most of the chloride ions are volatilized at high temperature and discharged out of the kiln during the clinker calcination process. . If the chloride ion content in cement is too high, the main source is mixed with admixtures and additives (such as industrial waste residue, grinding aids, etc.). Therefore, the requirement of "allowing the addition of grinding aids ≤0.5% in cement production and the chloride ion content in cement must be ≤0.05%" has been added to the new cement standard in China, which is mainly to ensure that cement is not correct. Excessive negative impact on concrete quality.
