| 6. | The destructive distillation of bituminous coal , done in the absence of air in order to obtain coke and other fractions having a greater percentage of carbon than the original material 碳化作用烟煤的分解蒸馏,在没有空气的条件下进行,为得到比最初的原料所含碳的百分比大得多的焦煤以及其它馏分 |
| 7. | Concrete protect the steel against corrasion , for it provide the alkaline condition . carbonization is a key factor that makes alkalescence of concrete decrease , the high performance concrete is applied in engineering field increasingly with its good carbonization capability 混凝土对钢筋的保护作用是由于其提供了避免钢筋产生锈蚀的碱性环境,而碳化作用是使混凝土碱性降低的重要因素之一。 |
| 8. | This paper presents an analysis method of mechanical behavior of aged concrete structures on elastic theory , and analyses the main causes of load bearing performance of concrete structures . the paper also illustrates some studies where structures exposed to the marine environment showed early deterioration and analyses the main causes of structural concrete deterioration , including concrete carbonization , corrosion mechanisms of concrete , and mechanisms of steel corrosion due to the penetration of chloride ions into the concrete . it shows that corrosion of the reinforcements is the main cause of structural concrete deterioration 本论文提出老化混凝土板的分层弹性理论,对混凝土结构的承载能力的影响进行分析;对浙江沿海混凝土结构及其构件的抗弯、抗剪、粘结性能以及结构的动力性能进行分析研究;提出了影响沿海混凝土结构耐久性的主要因素一混凝土的碳化作用,碱骨料反应,混凝土的腐蚀机理以及钢筋混凝土中钢筋锈蚀的影响因素。 |
