水泥石膏或聚合水泥是使用聚合物和纳米材料制备的合成石材，这些材料改变了水泥和矿物的分子结构，并由于聚合反应在水泥中产生强大的链网络。在这项工作中，加入碳酸钙纳米粒子（NPs）的水泥石膏的力学性能的影响进行了实验研究。为此，我们研究了添加0、0.5、1、1.5和2重量分数的碳酸钙NP对水泥石膏样品的拉伸和压缩强度的影响。实验获得的结果表明，添加1.5%的碳酸钙纳米颗粒使样品的拉伸强度提高了20%。然而，通过进一步添加碳酸钙NP，拉伸强度降低了22%。基于从压缩测试获得的结果，添加2%碳酸钙NP将样品的压缩强度提高了25%。此外，包含不同百分比的碳酸钙纳米颗粒的样品的弹性模量的预测的可能性，通过开发的理论方法进行了评估。
Cement plast or polymerized cement is a synthetic stone prepared using polymeric and nanomaterials which change the molecular structure of cement and minerals and create strong chain networks in cement due to polymerization reactions. In this work, the effect of the addition of calcium carbonate nanoparticles (NPs) on the mechanical properties of cement plast has been experimentally investigated. To do so, we investigated the effect of the addition of 0, 0.5, 1, 1.5, and 2 weight fractions of calcium carbonate NPs on the tensile and compressive strengths of cement plast samples. The experimentally obtained results showed that the addition of 1.5% calcium carbonate NPs improved the tensile strength of the samples by 20%. However, by further addition of calcium carbonate NPs, tensile strength was decreased by 22%. Based on the results obtained from the compression test, the addition of 2% calcium carbonate NPs improved the compressive strength of the samples by 25%. Also, the possibility of the prediction of the elastic modulus of the samples containing different percentages of calcium carbonate NPs by the developed theoretical method was evaluated.
