| 5. | In the concrete test cubes damages under freeze thaw cycles , the theory of the frost damages is explained and freeze - thaw test is done . from test results , the thesis analyzes the main reasons of frost damages 在冻融作用下混凝土试件的损伤部分中,首先阐述了混凝土的冻害机理,然后进行混凝土的抗冻试验,通过试验结果分析影响混凝土抗冻性的主要因素。 |
| 6. | The cold resistance and the water permeability resistance of the recycled coarse aggregate concrete were also test . the principle and the influencing factors of the drying shrinkage , the freeze thaw action and the water permeation action of the recycled coarse aggregate concrete were briefly narrated 还测试了再生粗骨料混凝土的抗冻性和抗渗性,简要叙述了再生粗骨料混凝土干缩变形、冻融作用、渗透作用的机理以及影响因素。 |
| 7. | Experiments indicated that compared with the native starch , the paste made of granular maize starch soluble in cold water prepared by alcoholysis showed higher apparent viscosity , higher stability of freeze thaw and lower retrogradation ; while the paste made of granular tapioca and potato starch soluble in cold water showed lower viscosity , stability of freeze thaw and retrogradation 试验证明,相对于原淀粉糊,醇解法制备的颗粒状冷水可溶玉米淀粉糊的表观粘度和冻融稳定性有所提高,凝沉性降低;颗粒状冷水可溶木薯和马铃薯淀粉糊的表观粘度、凝沉性和冻融稳定性均降低。 |
