FT-IR对原材料的验证必威手机客户端
用于制造水泥的必威手机客户端普通材料包括石灰石，贝壳和粉笔或泥浆以及页岩，粘土，石板，喷火炉炉渣，硅砂和铁矿石。
为了提供最佳产品，必须明确确定所使用的成分的身份和质量。由于使用了许多不同的原材料，因此需要一种真正的通用分析技必威手机客户端术。
FT-IR Spectroscopyanalyzes solids and liquids, whether organic or inorganic. It is easy to use and is generally non-destructive. Especially if organic additives are added, or for production of functional building materials, FT-IR is the ideal tool.

通过FT-IR评估混凝土的表面功能化和涂层
混凝土表面可以暴露于许多有害影响。这些包括环境压力，水分，还包括涂鸦。当将表面改进应用于混凝土时，必须对其进行验证和评估。
FT-IR Spectroscopyis used in the development and quality control of new types of concrete coatings, to test their functionality and optimize the coating process.
分析方法纯粹基于红外光的反射。因此，不必准备或损坏样品即可检查混凝土上的涂层。除此之外，即使是未经训练的人员，也可以在现场使用。感兴趣的？

Weathering of Concrete
具体适用下可以持续数千年e conditions. Nowadays we frequently find images of cracked and weathered concrete. As concrete is a mixture of many complex chemical compounds its durability depends on environmental conditions. Saltwater, for example, leads to chemical reactions that change the volume and lead to stress and strain in the concrete structure. Chlorine (Cl) is one of the most important elements to understand the aging and deterioration of modern concrete surfaces, as an increase in Cl leads to an expansion of the matrix, forming cracks and resulting in a loss of stability in any construction over time. Consequently, it is desirable to detect even small amounts of Cl in the matrix.
Micro-XRF has developed into a powerful technique to analyse concrete by elemental mapping of the surface of a drill core using theM4 Tornado Plus微XRF光谱仪。它允许快速测量大面积，在短时间内具有高分辨率，并提供组成信息以及相位分析，以快速估算水泥与骨料比。Read more

了解水泥微观结构
通常，对水泥和混凝土分析的浓度与表面相关，但是内部发生的事情同样重要。分配骨料，内部断裂和依从性的基础底物都是确保安装满足要求的关键。X射线显微镜允许可视化上述缺陷的水泥和混凝土sl。
Chemical Classification
最小的化学分类
Portland cement is one of the basic materials in the construction industry. The principal component of Portland cement is clinker. According to the cement nomenclature, clinker contains two silicate phases: Ca3SiO5（Alite）和CA2SiO4（Belite），以及铝制和铁氧体。Alite与Belite的比率负责水泥熟料中波特兰水泥的强度。在燃烧阶段确定该比率的能力对于评估水泥的最终强度至关重要。

Phase Analysis
XRD Phase Analysis of Cement
Both the manufacturing process as such and the quality of final cement products and the performance of the manufacturing process are predominantly defined by the phase (or mineralogical) composition. In the last decade, XRD has become the standard for true phase-sensitive analysis and is currently the most direct and the most reliable analytical technique for quantitative analysis of crystalline and amorphous phases. Most significantly, XRD analysis is performed in less than 5 minutes and thus exceeds outdated techniques like microscopical point counting or titrations or concepts that use indirect parameters or simplified models, such as the Bogue equations.
