Problems solved by technology

While some sulfur concretes exhibit good water and acid resistance, they do not perform well when exposed to flame
Also, when limestone is used as aggregate, damage due to water ingress can be severe

Embodiment

[0038] Several test mixtures of sulfur concrete were prepared. The weights of the mixture ingredients in the test mixture are shown in Table 2.

[0039] Table 2: Example mixtures.

[0040]

[0041]

[0042]

[0043] For Examples 3 to 6, two types of sulfur binders (ie, KFUPM-1 and KFUPM-2) developed by the inventors were used. In Examples 13 to 14 bitumen from a local refinery was used. The molded samples were held at about 130°C for at least 6 hours, after which the samples were allowed to gradually cool to room temperature.

[0044] A series of experiments were carried out with different examples incorporating sulfur to determine their fire resistance. Slab samples were prepared using Examples 1 to 14 detailed in Table 1 and exposed to flame. Table 3 describes the condition of the samples before and after exposure to the flame. As illustrated in Table 3, most of the systems evaluated exhibited low fire resistance. However, samples prepared with the composition...

Abstract

A sulfur concrete has constituents that include a coarse aggregate in an amount in a range of 40-50 wt% of the weight of the sulfur concrete, a fine aggregate in an amount in a range of 20-40 wt% of the weight of the sulfur concrete, a fine filler in an amount in a range of 8-12 wt% of the weight of the sulfur concrete, and a binder in an amount in a range of 12- 20 wt% of the weight of the sulfurconcrete. The binder includes elemental sulfur in an amount in a range of 25-60 wt % of the weight of the binder and asphalt in an amount in a range of 40-75 wt % of the weight of the binder.

Description

technical field [0001] The present disclosure relates to a refractory concrete. More specifically, the present disclosure relates to refractory concrete compositions using sulfur and methods of making the same. Background technique [0002] Sulfur, a by-product of petroleum refining, is now used to develop water- and acid-resistant concrete for the construction industry. While some sulfur concretes exhibit good water and acid resistance, they do not perform well when exposed to flame. Additionally, when limestone is used as aggregate, damage due to water ingress can be severe. Contents of the invention [0003] Embodiments of the present disclosure provide a refractory sulfur concrete that is also acid resistant and stable in water, regardless of the type of aggregate used. The composition of the present disclosure comprises bitumen and may have limestone aggregate, and the method of making the composition includes heating for more than six hours. Since the developed s...
