摘要
本研究的目的是调查两种重要的工业废物,硼石膏和硅灰,作为主要原料在生产建筑材料的利用。为此,从Emet硼酸厂(土耳其k塔哈亚)的硼废料(硼石膏)和从电冶金设施(土耳其安塔利亚)提取的硅灰中设计了不同的收据。配制混合料,使废料用量为90%,剩余10%为粘结剂粘土。将两种废弃物按不同比例进行单轴加压,分别在1000、1050、1100、1150℃下烧制成型样品。对烧制样品进行了物理和机械测试,以及矿物学和微观结构分析。根据废物的类型及其使用量和烧制温度,对从废物中提取的样品的技术特性进行了评估。据了解,使用高硼石膏会造成高烧成损失,这将对材料的尺寸稳定性产生负面影响。此外,硅灰加入硼石膏后,吸水率和孔隙率值增加,强度值相应降低。因此,从70%硼石膏和20%硅灰的混合物中制备的样品中获得的吸水率和弯曲强度值可以被认为是可能的,因为它们分别符合EN ISO 10545-3和EN ISO 10545-4标准中定义的技术性能。
Utilization potential of borogypsum and silica fume in producing lightweight building material
The present study is aimed at investigating the utilization of two crucial industrial wastes, borogypsum and silica fume, as the main raw materials in the production of building materials. For this aim, different receipts were designed from boron waste (borogypsum) belonging to Emet Boric Acid factory (Kütahya/Turkey) and silica fume, which was taken from Electrometallurgy facilities (Antalya/Turkey). Mixtures were prepared so that the amount of waste material used in the composition was 90%, and the remaining 10% was binder clay. The samples were prepared with different proportions of both wastes were pressed uniaxially at 10 MPa, and the shaped samples were then fired at 1000, 1050, 1100, and 1150 °C. Physical and mechanical tests, as well as mineralogical and microstructural analyses, were carried out on the fired samples. The technical properties of the samples derived from the wastes were evaluated depending on the type of waste material and its usage amounts, and firing temperatures. It has been understood that the use of high Borogypsum will cause high firing loss, which will negatively affect the dimensional stability of the material. Moreover, with silica fume addition to borogypsum, the water absorption and porosity values increased, and the strength values decreased accordingly. Consequently, the water absorption and bending strength values obtained in the samples prepared from a mixture of 70% borogypsum and 20% silica fume can be considered the usage as a wall tile is possible since they coincide with the technical properties defined in the EN ISO 10545-3 and EN ISO 10545-4 standards, respectively.
