“…Large amounts of it can be collected in plants consuming much fuel and cleaning emitted fumes and steam. The properties of sulphur are not exactly identical; they depend on various factors (Lvov Ukraina 1990; Abdel-Jawad, Al-Qudah 1994; Mohamed, El Gamal 2010;Vlahovič 2011). A major impact is made by the concentration of H 2 S. With its content increasing, the strength of sulphur is decreasing.…”

The article notes that not all types of plant origin waste are appropriate for being used as fuel or left for decay. The environment is polluted by noxious gas that is generated in the process of heating or decaying. Sulphur waste is produced at chemical and oil industry plants as well as during the treatment of emissions resulting from fuel combustion. Thermal energy is produced in the process of combusting plant origin waste; however, the emitted fumes are pollutants. A much more effective way for the use of this waste is proposed, i.e. to produce and use a new type of thermal insulation construction composites that would allow long-term heat saving buildings. The performed tests covered the properties of components and the influence of plasticisers on the plasticity and compressive strength of hardened sulphur. The common behaviour of sulphur and plant origin waste Á sawdust, boon, straw Á in composite was also analysed. All the properties necessary for thermal insulation materials were identified Á compressibility, compression and bending strength, thermal conductivity. They have the same value as other classical thermal insulation materials.

“…Otherwise, the volume change of about 7 % in the course of the cooling process leads to stresses and, in the end, the failure of the binder [54]. The addition of polymer prevents the growth of macro‐sulphur crystals [55] and leads to a lower coefficient of thermal expansion. However, the DCPDs 11 or DPs 12 required for the modification must be transported as additives from the earth to the moon because no hydrocarbon compounds are available on the moon.…”

“…The advantages over Portland cement concrete are its very rapid hardening, the fact that it takes only a little less than 24 h to reach its final strength, its better compression, tension and fatigue strengths compared with normal concrete and the ease of preparation at ambient temperatures < 0 °C [55]. Aggregate and sulphur are heated to a temperature between 132 and 141 °C, mixed and poured into the formwork [54].…”

This article provides an overview of the findings and production processes for the mineral materials that have been developed and tested worldwide in the past with regard to the establishment of a lunar base. Firstly, the aim of and procedure for constructing a lunar base are briefly outlined. Following that, the lunar environment factors and their influence on a possible structure are described. The paper then presents the advantages and disadvantages of the materials examined, such as sulphur concrete, cast basalt, lunar concrete or polymer concrete, on the one hand, as well as production processes investigated previously, such as sintering, geothermite reaction and 3D printing, on the other. One promising method is the dry‐mix/steam‐injection (DMSI) method for producing a lunar concrete as a possible material which was developed by T. D. Lin and is based on cement made from lunar resources.

“…Namely, there was evidence that no signs of degradation in more than 4 years of industrial testing in 50 process environments. This property of sulfur concrete can be attributed to sulfur (26)(27)(28)(29)(30)(31). Considering our experience in synthesis of sulfur polymer concrete with sulfur as a by-product from natural gas and oil production (28)(29)(30), and the fact that elemental sulfur is almost inert and does not react with water under normal conditions, thus excluding the occurrence of sulfate attack, sulfur can be successfully used in the production of SCC.…”

Effects of waste sulfur content on properties of self-compacting concrete

et al. 2020

View full text Add to dashboard Cite

Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert and to compare the properties of produced concrete samples. Fresh concrete properties included: slump-flow, t500, V-funnel time, L-box ratio, segregation ratio, density, and entrained air content. Hardened concrete was tested for compressive, flexural and bond strengths, ultrasonic velocity, dynamic elasticity modulus, dynamic Poisson’s ratio, and microstructure. Flowability and segregation increased, while bulk density, compressive and flexural strength, dynamic elasticity modulus and ultrasonic velocity slight declined. Times t500 and V-funnel time, L-box ratio and entrained air changed insignificantly. Considering that all properties should remain or improve in case of waste valorization and the criteria should set to satisfy requirements for SCC, this study proved that all mixtures can be used for structural applications.
