A method for producing a modified sulfur containing material which comprises a step (A) of melting and mixing sulfur and cyclopentadiene at 135 to 155 ° C in a closed system, a step (B) of cooling the resultant molten product having a viscosity of 0.05 to 1.2 Pa.s at 140 ° C to a temperature of 135 ° C or lower, to produce a modified sulfur containing binding agent, a step (C) of mixing and melting the binding agent and an aggregate at a temperature of 135 to 155 ° C, while maintaining a viscosity of the binding agent at 140 ° C within the range of 0.05 to 1.2 Pa.s, and a step of (D) of cooling the product to 135 ° C or lower. A modified sulfur containing material produced by the above method is good in mechanical strength, water-intercepting property, ignition resistance and the resistance to sulfur oxidizing bacteria, and thus can be used as a civil engineering or building material, even when a domestic or industrial waste is used as a law material aggregate, and the method allows the modified sulfur containing material and the binding agent for the material to be produced by the use of a simple and easy control.
