to study the influence of steel slag, slag and graphite content and age on the electrical conductivity of concrete, the electrical resistivity of concrete specimens with specifications of A(100mm×100mm×100mm) and B(100mm×100mm×400mm) was tested. The results show that: With the increase of curing age and the increase of cement substitution by steel slag: slag, the concrete resistivity continues to increase, and the electrical conductivity continues to decrease; and the optimal blending ratio of steel slag: slag is 1:2, the influence of graphite content on concrete conductivity Larger; as the size of the test piece increases, the electrical resistivity of the concrete decreases.
