摘　　要：研究了PVC、PP、PE、PP-R四种塑料建筑模板的基本力学性能,以及在混凝土水化热模拟试验条件下的伸缩性能。结果表明,PVC塑料建筑模板的比强度为44N·m/kg,高出其他三种塑料建筑模板30%以上;平均线膨胀膨胀系数为2.4×10-5/℃,与混凝土较为接近,且二者具备良好的协调变形能力。In this paper, the basic mechanical properties of PVC, PP, PE, PP - R four kinds of plastic building templates were studies, as well as in concrete hydration heat simulated test conditions stretch ability. The results showed that the specific strength of PVC plastic building template is 44N · m/kg, higher than the other three plastic construction template 30% ; average linear expansion coeffi- cient of expansion is 2. 4 ×10^-5/℃, which is closer to the concrete , and good coordination between the two deformation capacity.
