对提高混凝土耐久性的思考

Thought on Improving the Durability of Concrete

长期以来从单方面因素考虑是混凝土耐久性研究的误区。笔者通过分析影响混凝土耐久性的诸多因素后,提出了合理应用新技术混凝土以保持其高度体积稳定性;掺入添加荆,有效改善混凝土的性能;运用质量良好、技术性能指标合格的砂石骨料;严格控制水胶比等提高混凝土耐久性的措施,有一定的工程实用价值。

For a long time people have made study on the durability of concrete from a single aspect, and this has led to failure. The author analyzes the factors affecting the durability of concrete, and suggests that the concrete made by new technology be applied to maintain its stability in height and size. Besides, other measures can be taken to improve the durability, for instance: to mix some additives into concrete to improve its feature; to use high quality, technically standard sand and stone and to control the ratio between water and glue. All these will be of practical value.
