摘要
研究掺聚醋酸乙烯水泥砂浆的轴拉和轴压应力—应变关系、抗弯性能以及长期粘结抗弯强度。试验结果表明 ,掺入聚醋酸乙烯能有效改善砂浆的变形力学性能和粘结强度、施工和易性、并具有良好的耐久性。聚合物砂浆可广泛应用于粘结、修补及结构加固中的钢板粘贴和表面粉刷等。
This paper delivered the relationships of uniaxial tensile and compressive stress with strain and bending properties, and felt-bending strength of cement mortar with polyvinyl acetate(PVAC). Test results show that, with adding of PVAC, the polymer-mortar possessed excellent felt-bending properties,especially for the long-term durability. Therefore, the deformation and mechanical properties of mortar can be improved efficiently by adding PVAC. Furthermore, the workability of PVAC-mortar has been ameliorated. Hence, the polymer-mortar can be widely used as agglutinating of old-fresh concrete, sticking steel plate and surface whitewashing at structure feinforced.
