Structural and Durability Properties of MgO-Al2SiO3 Concrete for ISRU Martian Construction
The development and properties of MgO-clay-based engineered M-S-H cement mortar and concrete with Martian regolith simulant filler is presented in this study. Engineering properties for the M-S-H cement include compressive strength, tensile strength, Poisson’s ratio, elastic modulus, bond strength, and incorporate durability indicators such as porosity, permeability, and resistivity. Additionally, the structural response of reinforced engineered M-S-H concrete columns under lateral loads is compared with the performance of columns cast with conventional portland cement (PC) concrete. These findings demonstrate that the properties of the MgO-clay cement concrete can be effectively manipulated through variations, either in the cement formulations or in the mix proportions, to suit the functional requirements of proposed Martian applications. Engineering properties and the structural performance of the reinforced concrete sections made with the engineered M-S-H concrete were similar to those demonstrated by the columns made with PC concrete, thereby, making it a suitable material for both Martian and Earth-based construction.
