摘要

这项工作的目的是制备和表征含有轻质聚集体的地聚合物复合材料-珍珠岩和蛭石。以粉煤灰、砂子和6M氢氧化钠水玻璃溶液为原料制备地聚合物基质。样品制备后28天对材料的性能进行测试。采用以下研究方法对复合材料进行表征:压缩和弯曲强度测试,使用扫描电子显微镜进行微观结构测试,并测量导热系数。结果表明,添加剂对强度性能影响不大。轻质聚集体的特点是与基体材料具有良好的相干性。它们的加入降低了密度,降低了材料的导热性。结果表明,所提出的添加剂可以改善地聚合物复合材料的性能,可用于建筑行业。进一步的研究应集中在珍珠岩地聚合物复合材料上,并进行耐火和吸水试验。轻质建筑材料的生产带来了许多好处,例如减少了建筑元素的密度,同时,整个结构,从而减少了它们的重量,以及降低了运输成本。这些元素具有更好的隔热和隔音性能,体现在建筑的参数上。另一个优点是通过更好的绝缘性能,降低运输过程中的燃料消耗等减少对环境的影响。材料的密度可以通过使用轻质骨料或在发泡过程中获得多孔材料来降低。就地聚合物复合材料而言,已经提供了许多与泡沫材料有关的研究,但只有少数先前的研究与珍珠岩和蛭石等轻质聚集体有关。

Development of lightweight geopolymer composites containing perlite and vermiculite
The aim of this work was to prepare and characterise geopolymer composites containing lightweight aggregates - perlite and vermiculite.The geopolymer matrix was prepared on the basis of fly ash, sand and a 6M sodium hydroxide solution with sodium silicate. The properties of the materials were tested 28 days after the preparation of the samples. The following research methods were used to characterise the composites: compressive and flexural strength tests, microstructural tests using a scanning electron microscope, and thermal conductivity were measured.The results obtained showed a slight effect of the additives on the strength properties. Lightweight aggregates are characterised by good coherence with the matrix material. Their addition allowed to reduce the density and lowered the thermal conductivity of the materials. The results obtained indicate that the proposed additives can improve the properties of the geopolymer composite for use in the construction industry.Further research should focus on geopolymer composites with perlite and involve fire-resistant and water-absorption tests.The production of lightweight building materials brings a number of benefits, such as reducing the density of building elements and, at the same time, the entire structure, which results in a reduction in their weight, as well as lower transport costs. Such elements have better thermal and acoustic insulation, reflected in the parameters of buildings. An additional advantage is the reduced environmental impact through better insulation properties, lower fuel consumption during transport, etc.The density of the material can be reduced by using lightweight aggregates or obtaining porous material in the foamed process. In the case of geopolymer composites, a number of studies related to foamed materials have been provided, but there is only a few previous research connected with lightweight aggregates such as perlite and vermiculite.
