Construction by Contour Crafting using sulfur concrete with planetary applications

Purpose - This paper aims to report on the experiments with the Contour Crafting Automated Construction process using sulfur concrete as the choice of construction material. Design/methodology/approach - Several experiments have been performed at centimeter and meter scales. A finite element analysis simulation model for the behavior of sulfur concrete-based structures has been developed. Experimental results were compared with the results of simulation. Findings - Sulfur concrete has numerous terrestrial applications and is potentially an ideal construction material for planetary construction. Originality/value - Experimental samples of sulfur concrete were fabricated using a novel mixer/ extrusion system. The mechanism was proven to be durable and stable after more than 500 h of work.
