Water is a precious resource in red planet. So, use of normal concrete for any development in Mars is not imaginable nor sustainable. Composition of Martian Concrete. As mentioned above, the key material used for making Martian concrete is sulphur. The concept behind this is that when sulphur is heated to 240 degree celsius it becomes liquid.
SC also known as Sulphurcrete is a thermoplastic concrete mixture which composed of fillers such as coarse aggregate, fine aggregate, fly ash etc. and melted sulphur, mixed at a temperature above 120o C to get a homogeneous mixture [1, 2, 3]. Unlike NC, water and cement is not used in SC, which improves the durability properties of SC.

Physical properties. Sulfur forms several polyatomic molecules. The best-known allotrope is octasulfur, cyclo-S 8.The point group of cyclo-S 8 is D 4d and its dipole moment is 0 D. Octasulfur is a soft, bright-yellow solid that is odorless, but impure samples have an odor similar to that of matches. It melts at 115.21 °C (239.38 °F), boils at 444.6 °C (832.3 °F) and sublimates easily.
ØSulphur concrete is a composite construction material, composed of sulfur, coarse aggregate & sand. ØSulphur is heated to bring it into molten condition to which coarse and fine aggregate is poured and mixed together. ØOn cooling, this mixture gave fairly good strength, exhibited acid resistance and also other chemical resistance, but it ...
Low kiln temperatures in the burning of lime, lack of pozzolana, and poor mixing all contributed to a decline in the quality of concrete and mortar. From the 11th century, the increased use of stone in church and castle construction led to an increased demand for mortar.

Lunarcrete, also known as " mooncrete ", an idea first proposed by Larry A. Beyer of the University of Pittsburgh in 1985, is a hypothetical construction aggregate, similar to concrete, formed from lunar regolith, that would reduce the construction costs of building on the Moon. [3] AstroCrete is a more general concept also applicable for Mars.
