【摘要】 采用Shimadzu DSS-25t试验机测试了低掺量聚合物水泥砂浆的断裂能,结果表明采用磨细矿粉及少量外加剂改性的低掺量聚合物水泥砂浆具有较大的断裂能,同时发现砂灰比对聚合物水泥砂浆的断裂能有重要影响。更多还原

【Abstract】 In this paper, the fracture energy of low content polymer modified cement mortar with superfine powder and chemical additive was measured with Shimadzu Dss-25T test machine. Results show that Low content polymer modified cement mortar with superfine mineral powder and chemical additive has Larger fracture energy than that of those without them. Furthermore, we have concluded that the ratio of sand to cement also has great influence on fracture energy of cement mortar.更多还原
