现浇钢渣混凝土薄壁管桩强度特性试验研究

通过试验研究了废钢渣作为原材料配制混凝土的方法，并将钢渣混凝土与普通混凝土在配制过程中的某些性质指标作了比较，分析其原因，并在试验的基础上建立了强度与水灰比经验公式，为工程设计提供了依据。配制出的钢渣混凝土力学性能比普通混凝土力学性能要高，而且节省了水泥和石子，具有很好的经济效益。由于利用了废物，变废为宝，解决了环境污染问题，故又有很好的社会效益。

Test study on strength of casted-in-situ thin-wall pipe pile with steel-slag concrete

In order to reduce the quantity of the unused steel-slag and take full advantage of their useful values in pile foundation, the research is conducted on the confecting method of steel-slag concrete. Through comparison of the physical and mechanical properties between steel-slag concrete and plain concrete, we can analyze the advantages of using steel-slag concrete. Based on the test, an empirical formula is developed, which provides some bases for practical projects. The mechanical properties of steel-slag concrete prevail over that of the plain concrete; also the quantities of cement and gravel are reduced, consequently reducing the capital cost of the project materials; so this method is economically and safely to use and it can solve the environmental problems of unused steel-slag.
