Experimental and parametrical investigation of pre-stressed ultrahigh-performance fiber-reinforced concrete

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 3,   Pages 411-428 doi: 10.1007/s11709-023-0928-3

Abstract: In this study, ultrahigh-performance fiber-reinforced concrete (UHPFRC) used in a type B70 concrete sleeper is investigated experimentally and parametrically. The main parameters investigated are the steel fiber volume fractions (0%, 0.5%, 1%, and 1.5%). Under European standards, 35 UHPFRC sleepers are subjected to static bending tests at the center and rail seat sections, and the screw on the fastening system is pulled out. The first cracking load, failure load, failure mode, crack propagation, load–deflection curve, load–crack width, and failure load from these tests are measured and compared with those of a control sleeper manufactured using normal concrete C50. The accuracy of the parametric study is verified experimentally. Subsequently, the results of the study are applied to UHPFRC sleepers with different concrete volumes to investigate the effects of the properties of UHPFRC on their performance. Experimental and parametric study results show that the behavior of UHPFRC sleepers improves significantly when the amount of steel fiber in the mix is increased. Sleepers manufactured using UHPFRC with a steel fiber volume fraction of 1% and a concrete volume less than 25% that of standard sleeper B70 can be used under the same loads and requirements, which contributes positively to the cost and surrounding environment.

Techno-economic comparison of three technologies for pre-combustion CO

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 3,   Pages 436-452 doi: 10.1007/s11705-019-1870-8

Abstract: This paper compares the techno-economic performances of three technologies for CO capture from a lignite-based IGCC power plant located in the Czech Republic: (1) Physical absorption with a Rectisol-based process; (2) Polymeric CO -selective membrane-based capture; (3) Low-temperature capture. The evaluations show that the IGCC plant with CO capture leads to costs of electricity between 91 and 120 €·MWh , depending on the capture technology employed, compared to 65 €·MWh for the power plant without capture. This results in CO avoidance costs ranging from 42 to 84 €· , mainly linked to the losses in net power output. From both energy and cost points of view, the low-temperature and Rectisol based CO capture processes are the most efficient capture technologies. Furthermore, partial CO capture appears as a good mean to ensure early implementation due to the limited increase in CO avoidance cost when considering partial capture. To go beyond the two specific CO -selective membranes considered, a cost/membrane property map for CO -selective membranes was developed. This map emphasise the need to develop high performance membrane to compete with solvent technology. Finally, the cost of the whole CCS chain was estimated at 54 €· once pipeline transport and storage are taken into consideration.
