The Effect of Silica Fume on the Physical Properties of Molten Sulfur Dry Concrete
In this study, we investigated the effect of silica fume with ratios of 10, 20, 30, 40, 50, 60% of the total weight of sulfur dry concrete. After melting at 175 ° C, sulfur powder was mixed with preheated microsilica that reached the level of molten sulfur powder and then poured into molds. In this paper, 189 samples in different forms, including a 10 cm cube for compressive strength test, a 5 cm cube for acid resistance, melting and freezing tests, and a 16 x 4 x 16 cm sample for flexural strength have been prepared. The samples were tested 1, 24 and 72 hours after concreting according to the pre-tests. All samples are stored in the laboratory and poured into molds. An oven in the laboratory was used to bring the sulfur powder to the melting point. Sulfuric acid has been used to test its.
