Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 DC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 %filler and 58 % aggregates. The effects ofreaction temperature, and heating time, were tested on mechanicalproperties ofsulfur mortar. Sulfur mortars were prepared by silica flour, mica
and carbon as filler in which silica flour can reduce odor problems. Sulfur mortar specimens have compressive strength (200-424 kg/cm2), tensile strength (more than 80 kg/cm2), and flexural strength (110-120 kg/cm2).
