This paper shows the characterization of a new lightened gypsum-based material for use in buildings. A plaster material has been designed with a polymeric compound based on polyvinyl acetate, bicarbonate and a boric acid solution, which reduce the density and thermal conductivity by up to 20% and 30%, respectively. In addition, tests have been carried out with the lightened plaster material reinforced with glass (GF), basalt (BF), polypropylene (PPF) and wood (WF) fibers. A significant improvement in mechanical properties was achieved. All samples obtained resistance values greater than 2 MPa in flexion and 3 MPa in compression. Physico-chemical analysis were also carried out. The study is completed with a statistical analysis, where confidence intervals have been obtained for the mean at 95% confidence for each of the physical properties studied.

本文展示了一种用于建筑的新型轻质石膏基材料的特性。一种石膏材料已被设计出来，它含有基于聚醋酸乙烯酯、碳酸氢盐和硼酸溶液的聚合物化合物，分别使密度和热导率降低了20%和30%。此外，还对用玻璃（GF）、玄武岩（BF）、聚丙烯（PPF）和木材（WF）纤维增强的轻质石膏材料进行了测试。实现了机械性能的显著改善。所有样品在弯曲时的电阻值大于2 MPa，在压缩时大于3 MPa。还进行了物理化学分析。该研究以统计分析完成，其中针对所研究的每种物理性质，在95%置信度下获得了均值的置信区间。
