摘　　要：对石墨导电混凝土的力学性能及热电特性进行实验,力学性能以28d的抗压强度为标准,热电特性以温差电势表征.实验结果表明,当石墨质量分数每增加5%时,强度约减少50%;温差电势一般仅发生在导体中,在实验中也发现这种现象,且低石墨质量分数导电混凝土的热电效应近似呈线性关系,并有线性分段的现象.通过对实验数据的回归,得到电动势与温差的函数表达式.Test studies are applied to mechanical and thermoelectric property of graphite electrically conductive concrete(GECC).The 28 days Compressive strength acts as the indicator of mechanical property.The test shows that compressive strength of GECC decreases by half as graphite's mass content increases by 5%.So it's important for GECC application to deal well with relation of strength and conductivity.Thermoelectric potential acts as the indicator of thermoelectric property.Thermoelectric potential just appears to conductor,but the same phenomenon appears to GECC.Furthermore,relationship between thermoelectric value and temperature is piecewise linear.Formulas about electromotive force and temperature difference are presented after analyzing the testing data.The thermoelectric potential mechanism of GECC need to be further researched.
