The invention belongs to the field of composite materials, and particularly relates to electroconductive concrete using dodecylbenzene sulfonic acid doped polypyrrole as an electroconductive component and a preparation method of the electroconductive concrete.The electroconductive concrete is made from, by weight, 100-200 parts of cement, 100-200 parts of sand, 10-100 parts of dodecylbenzene sulfonic acid doped polypyrrole, 0.1-1 part of a dispersant and 80-100 parts of water.The preparation method includes: mixing dodecylbenzene sulfonic acid doped polypyrrole, dispersant and water according to the above weight parts; ball-milling for dispersion; fully stirring and mixing dispersion liquid with cement and sand of the weight parts; pouring a mixture into a formwork, demounting the formwork, and maintaining.The electroconductive concrete prepared by the method has quite excellent electroconductivity, and resistivity of the electroconductive concrete can be lowered to 15Omega.cm; other performances are excellen
