Phase-theory driven development of glasses and methods for the preparation of continuous protective glass layers on concrete.

这项宏伟的提案描述了无机玻璃材料的发展和适用于生产保护混凝土表面的玻璃涂层的应用工艺。与最初的研究建议不同，应研究耐热中间层，以承受短时间的温度暴露，同时进行火焰祈祷，以实现200至1000微米的玻璃应用。火焰玻璃层应起到保护底层混凝土免受酸性溶液(如污水系统中的生物硫酸)以及其他酸侵蚀、氯化物或碳化的作用。此外，还考虑了作为建筑立面材料的光泽、颜色和质地。目标是开发用于保护混凝土的不透水、耐用、粘结剂和对环境负责的玻璃层。使用方法是火焰喷雾。到目前为止的结果表明，成功应用需要一层耐热材料。为此，应使用薄层玄武岩砂浆，这些砂浆经证明能够承受短期的热暴露，但由于温度梯度较大，应从混凝土中分离出来。应调查极短时间热暴露的影响以及陡峭的温度梯度的影响。目标是以基础研究为基础，同时考虑到禁止以后在建筑施工中使用的所有方面。

This grand proposal describes the development of inorganic glass materials and a suitable application process for the production of glass coatings for the protection of concrete surfaces. Differently from the original research proposal, thermal persistent intermediate layers shall be investigated to endure the short timed temperature exposure while flamespraying to enable an application of glass of between 200 to 1000 micrometre.The flamesprayed glass layers are supposed to act as protection of the underlying concrete against acidic solutions, such as biogenic sulphuric acid in sewage systems, as well as other acid attacks, chlorides or carbonation. Furthermore, a use as architectural facade material concerning gloss, colour and texture is considered. The objective is the development of impermeable, durable, adhesive, and environmentally responsible layers of glass for the protection of concrete. The method for application is flame spraying. The results so far show, that a layer of a thermal persistent material is needed for the successful application. For this, thin layers of a basalt mortar shall be used which proofed to be able to endure the short timed heat exposure, but are detached from the concrete due to the steep thermal gradients. The influence of extreme short timed heat exposure as well as the influence of steep thermal gradients shall be investigated.The objective if based on fundamental research though considering all aspects prohibiting a later use in building constructions.
