“…So far, several groups have demonstrated the feasibility of sintering of lunar regolith and regolith simulants. [7][8][9][10] A thermal analysis of the lunar regolith simulant Johnson Space Center 1A (JSC-1A) has revealed a basaltic glass transition temperature at 640°C and a major endothermic peak associated with the melting temperature at 1150°C. 9 This matches reasonably well with the data reported by Ray et al, 27 which reported temperatures of 647°C and 1120°C respectively.…”

“…Missions to mars will require a temporary base on the Moon, consequently several options to create structures on the Moon using available lunar soil are discussed and under investigation. [1][2][3][4][5][6][7][8][9][10][11] If insitu materials could be used on the Moon (such as regolith or regolith derived concrete), to build large civil engineering structures, then extensive amounts of mass launched from Earth could be avoided, making space exploration more economical and hence possible. 12 For a mind-setting, this communication starts with a closer look to the environmental conditions present on the Moon and their effect on envisaged fabrication technology for structural constructive elements.…”

The feasibility of creation of structures on the Moon using lunar soil as in-situ resource and sintering additive manufacturing technologies is discussed. The use of sintering technologies for additive manufacturing and construction using lunar regolith has already been demonstrated. However, an important point of attention for applying such a process under lunar conditions is the generation of volatiles during heating of the solid particles to the sintering temperature and the possible pyrolysis of the material at temperatures higher than the temperatures required for sintering. The analysis of the available data shows, that the production of constructive elements out of regolith with a guaranteed mechanical performance is feasible by maintaining a precisely tuned process controlling the maximum temperatures reached and minimum times required for the sintering of the particles of lunar soil to solids essential for the formation of parts usable for construction of e.g. temporary habitats.

“…While higher amounts of fibre can improve the buildability due to the high yield stress, they can also hinder extrudability. Using locally sourced materials from the UK, such as basalt rock to produce basalt fibre [ 38 ], researchers improved flexural strength in basalt fibre-reinforced printed elements by fibre-reinforcing the cementitious matrix or increased the flexural toughness of high-performance fibre-reinforced concrete (HPFRC) [ 36 , 39 ].…”

Optimisation of Mix Proportion of 3D Printable Mortar Based on Rheological Properties and Material Strength Using Factorial Design of Experiment

et al. 2023

In the production of 3D printable mortar (3DPM), numerous efforts have been made globally to effectively utilise various cementitious materials, admixtures, and fibres. The determination of rheological and material strength properties is crucial for successful 3D concrete printing because the materials used in 3DPM must possess the unique characteristic of making mortar flowable while being strong enough to support the weight of subsequent layers in both fresh and hardened states. The complexity of the required characteristics makes it challenging to develop an optimised mix composition that satisfies both the rheological and material strength requirements, given the wide range of available admixtures, supplementary cementitious materials, and fibres. Fly ash, basalt fibre and superplasticiser when blended with cement can help to improve the overall performance of 3DPM. The objective of this research is to optimise the rheological properties and material strength of 3D printable mortars (3DPM) containing cement, fly ash, basalt fibre, and superplasticiser. This study aims to produce 3DPM with an optimised mix composition to meet the requirements of both rheological and material strength characteristics using the factorial design approach and desirability function. Different dosages of cement, fly ash, basalt fibre, and superplasticiser are chosen as the primary design parameters to develop statistical models for the responses of rheological and material strength properties at 7 and 28 days. The results expressed in terms of the measured properties are valid for mortars made with cement ranging from 550 to 650 kg/m3, fly ash from 5% to 20% (of cement), superplasticiser from 2 to 4 kg/m3, and basalt fibre from 1 to 3 kg/m3. The rheological properties are evaluated using slump flow, cone penetrometer, and cylindrical slump tests, while the mechanical strength is evaluated using a three-point bending test and compressive test. A full factorial design experiment (FoE) is used to determine the significant parameters effecting the measured properties. Prediction models are developed to express the measured properties in terms of the primary parameters. The influence of cement, fly ash, basalt fibre, and superplasticiser is analysed using polynomial regression to determine the main effects and interactions of these primary parameters on the measured properties. The results show that the regression models established by the factorial design approach are effective and can accurately predict the performance of 3DPM. Cement, fly ash, and superplasticiser dosages have significant effects on the rheological and mechanical properties of mortar, while basalt fibre is able to influence the static yield stress and flexural strength of 3DPM. The utilisation of regression models and isoresponse curves allows for the identification of significant trends and provides valuable insight into the behaviour of the material, while desirability function is useful to optimise overall performance of mix proportions to meet the desired performance objective at fresh and hardened states.
