基于正交试验的钢纤维混凝土电阻率的研究

Observations on the electrical resistivity of steel fiber reinforced concrete on orthogonal test

为地铁工程中的钢纤维混凝土的应用提供试验依据,研究采用正交实验法,研究钢纤维含量、粉煤灰掺量、阻锈剂掺量三个因素对钢纤维混凝土的电阻率影响规律。结果表明:粉煤灰掺量对于材料的电阻率有显著影响,钢纤维含量和阻锈剂含量对于材料的电阻率影响不大。

The experimental study provides a basis for the use of steel fiber reinforced concrete in underground engineering. The influence of three factors such as ratio of steel fiber, ratio of fly ash and ratio of rust inhibitor on the resistivity of steel fiber reinforced concrete is stud- ied through orthogonal tests. Experimental results show that： the influence of ratio of fly ash on the resistivity of steel fiber reinforced con- crete is the most obvious. The ratio of steel fiber and rust inhibitor has a little influence on the resistivity of steel fiber reinforced concrete.
