This study focuses on production of lightweight concrete that presents thermal insulation property. Lightweight concretes were produced using resin-added cement and expanded vermiculite. The rates of expanded vermiculite were determined as 20%, 40%, 60%, and 80% of the total volume in the mixture. The amount of tragacanth resin in the mixture was detected as 0%, 0.5% and 1% of the total weight of cement and expanded vermiculite. Thermal, mechanical and microstructure properties of the samples produced were determined. Porosity ratio increased by 15.01% to 55.22%, 0.5% and 1% in samples without resin and by 18.97% to 57.88% and 19.64% to 60.73% in resin-added samples, respectively. As the resin increased, density, thermal conductivity, compressive strength decreased and porosity, abrasion loss and water absorption rates increased. Similarly, when expanded vermiculite rate of the samples without resin in the mixture was increased from 20% to 80%, density, thermal conductivity, and compressive strength decreased at the rates of 14.13% to 21.29%, 14.32% to 24.36%, and 31.37% to 39.82%, respectively, compared to 0.5% resin samples and the rates of 12.34% to 13.05%, 12.37% to 19.59%, and 17.65% to 35.29% compared to 0.1% resin samples. Also, the water absorption rates of the samples were found to be lower than 30%, which is the critical value. It was shown that expanded vermiculite and tragacanth resin-added lightweight concrete samples would provide a good performance in non-load bearing places in the buildings, in the partitions instead of bricks, in the ceiling and floor covering, and as plaster and gypsum.

天然树脂对膨胀蛭石-水泥复合材料热物理性能的影响

本研究侧重于具有隔热性能的轻质混凝土的生产。使用添加树脂的水泥和膨胀蛭石生产轻质混凝土。膨胀蛭石的比例确定为混合物中总体积的 20%、40%、60% 和 80%。混合物中黄蓍胶的含量分别为水泥和膨胀蛭石总重量的0%、0.5%和1%。测定了所生产样品的热、机械和微观结构特性。无树脂样品孔隙率分别增加 15.01% 至 55.22%、0.5% 和 1%，添加树脂样品分别增加 18.97% 至 57.88% 和 19.64% 至 60.73%。随着树脂的增加，密度、热导率、抗压强度降低，而孔隙率、磨损损失和吸水率增加。相似地，当混合物中不含树脂的样品的膨胀蛭石率从20%增加到80%时，密度、热导率和抗压强度分别以14.13%到21.29%、14.32%到24.36%和31.37%到分别与 0.5% 树脂样品相比的 39.82% 和与 0.1% 树脂样品相比的 12.34% 至 13.05%、12.37% 至 19.59% 和 17.65% 至 35.29% 的比率。此外，发现样品的吸水率低于临界值 30%。结果表明，添加膨胀蛭石和黄蓍树脂的轻质混凝土样品在建筑物的非承重场所、隔墙代替砖、天花板和地板覆盖物以及石膏和石膏中具有良好的性能。
